One of my favourite South African bulbs, Lapeirousia oreogena, is flowering better than ever before this year. The flowering season lasts a fair time as it produces a succession of flowers over a long period. It has one of those colours that digital cameras seem to find hard to register properly so I have "doctored" the image below to try and get it closer to the actual colour. It still isn't quite right; the flowers are in reality a richer, darker violet.

I did toy with posting this on the 'Moans' thread but as I have a question about a SAF bulb I'll leave it here.

My seeds from Gordon Summerfield, ordered in November (!), finally arrived today. It wasn't Gordon's fault. Forumists who've been dealing with South Africa will know they've been having a series of postal strikes - and apparently another strike is due as they want back pay for the time they were on strike earlier! So Gordon at some expense had to use a courier service to ensure seed orders were fulfilled which was very considerate of him. Unfortunately the courier company seemed to be staffed by cretins as they claimed that they had tried to deliver to me but I had refused to accept the package  :-[ ??? >:( Of course, the problem was that they had messed up the postcode so it went to the wrong address ( I also noticed that my phone number on the waybill was also incorrect!). Anyway, it has now been sorted although the strike could be ruinous for some seed companies. Gordon emailed to say:

One of the growers that we supply seed to has said they are on the edge of going out of business, as so many of their packages sent via the Post Office took many months last year and the contents were all ruined.   Being a large business that sells large quantities they just cannot afford the courier fees.

So, one of my seed packets is Romulea hantamensis and I wondered if any forumists have experience of this species? I ask because the PBS reports that it is tricky to germinate, possibly requiring stratification. Anyone grown this from seed and if so did they give it a period of winter cold or just the usual regime for SAF winter growers of a temperature differential until germination? Thanks.

Lachenalia aloides quadricolor
Hi Arnold,
Was this grown for seed? I know it is very variable but the best selections keep the four distinct bands of colour and it is not always consistent. I think the form "Pearsonii" is one that has pure yellow flowers developing from reddish buds like yours does,

Really like the pendula Arnold.  Looking at my Quadricolor last year I wondered if the variation were climatic, instability or bulbs were simply reverting as they multiple like wildfire, some even to plain yellow.  Started with one bulb from Transpacific back in the 90's.

Guess I should check this year's crop.

Steve,

I  sowed Romulea hantamensis seeds from Silverhill in 2011, gave the pot varying temperatures
which did not result in germination.  In 2014 I dumped the pot contents in the garden in one
of the spots reserved for non-performers.  Always give them a chance, not that many take
advantage.

I've had seed from Gordon arrive in January before. It matters little as even November is really too late to be sowing them here, plus they have just been harvested and many of them need a post-harvest warm dry ripening before sowing anyway therefore I'd put them in a drawer in the house until August and sow them then. I can understand your frustration though.

I've had seed of R. hantamensis several times and given it both normal SA bulb treatment and tried leaving it outside for the winter. Neither was successful.

Diane/Darren - many thanks for sharing your experiences of R. hantamensis. Doesn't sound very encouraging but I suspected as much when ordering the seed - we're an optimistic lot when it comes to plants, aren't we?! Anyway, I'll give it a go and hope for the best. If I do get any to germinate I'll bear you both in mind  :).

Hi Darren - I agree with you up to a point, particularly on the post-harvest ripening requirements, but I have successfully sown these winter growers at different times with some success. My previous order from Gordon did arrive in November and as the seed allocation was fairly generous and I'm an impatient b*gg*r, I sowed half the packet and put the rest away until the following August. Kept the pots in the house, moving them to a cooler room every night and had really good germination. Of course, it meant the young bulbs were smaller than usual when they were going into dormancy but by growing them on for as long as possible and not letting them bake over summer they all reappeared in the autumn and it meant I saved a year. It would be a bit of a hassle for large quantities but I was happy to take a punt on a single tray of seed pots. Didn't work for Wurmbea recurva, Gladiolus meluisculus, Lachenalia arbuthnotiae and L. pusilla but these species didn't germinate from the August sowing either! ::)

Yes, that might be worth a try although - and excuse my ignorance of the region - I'm not sure whether fire is a frequent occurence in the Hantamberg area or indeed whether montane species are particularly dependent on fire/smoke for germination.

I'm no expert Erle but I don't think it is and I'm surprised some of the South African experts haven't been in on this one. Apparently Romulea reflexa is a synonym of R. flava and R. flava is a synonym of R. rosea var. reflexa. Perhaps the best picture I can find is on the Pacific Bulb Society pages http://www.pacificbulbsociety.org/pbswiki/index.php/SouthAfricanRomuleasTwo#flava (http://www.pacificbulbsociety.org/pbswiki/index.php/SouthAfricanRomuleasTwo#flava)  and you may well find there some information that will help.

The choices used to be metal halide or HPS lamps but LEDs seem to be making inroads: http://www.heliospectra.com/ (http://www.heliospectra.com/) (click on Reviews to read what Gothenburg has to say).

Anyone had experience of using horticultural LEDs? Much cheaper to run than high pressure sodium lamps, I assume, which may make them an attractive option to boost winter light levels here in Yorkshire. Although I suspect the neighbours would still wonder what exactly I'm growing in the greenhouse regardless of the source of the light!  ;D

I've been using a HID mercury vapor bulb for years over some of the South African bulbs.

The LED"S are out there but cost can range 200-300 dollars per bulb. 

I would have tired one bulb the fixture housing the bulb would have to be changed.  The LED's don't require the ballast needed  for an HID.
Title: Re: South African Bulbs 2015
Post by: Rimmer de Vries on March 10, 2015, 11:43:34 AM
I use 54 watt T-5 fixtures to grow all my winter bulbs and they work wonderfully but they are not cheep fixtures or very cheep to run but much less cost than the old type of grow lamps and put out much stronger light than the typical T-8 or T-12 fluorescent shop lamps. These fixtures with bulbs can cost $100 to $200 depending the number of bulbs, there is always a sale somewhere.  This solution was much cheeper than installing a greenhouse and does not need supplemental heating in our sub Arctic winters down to -30ºC

These fixtures have two switches so you can choose the outer 4 lamps and/or the inner 2 or 4 lamps and have an extra outlet so you can daisy chain fixtures or plug in a fan.  because they give off heat (just like the sun) i use 6" fans on the same timer to cool off the grow space and stiffen up the stems.  the first year i ran these fixtures with all the light bulbs on, but this year i have mostly used the outer 4 light bulbs and turned on the extra light bulbs when i see flower stems popping up.

the fixtures come with 6400K 54watt T-5 light tubes but you can use 24watt  and get other light band widths.   the 6400k work well for flowering plants. 

The plants grow wonderfully but some plants not used to the bright light get scorched and others need the full light. so plant positions need to be sorted out.   for the coolest growing south African bulbs i have the pots and trays on the basement floor in a sand plunge with the light about 2.75 feet above the floor.  this areas is typically below 50ºF at night and gets to the 60sºF when the lamps are on with the fans.  other ZA plants the South Americans that do not need the cold below 60ºF are located on a table, shelf etc.  with the lights at varying distances from the plants.

I have tried the screw socket style blue and red LED grow light sold on eBay from China that have dozens of tiny LEDs and the plants seem to grow tight but some plant leaves turn black under this light.  these LEDs are not supposed to give IR but i wonder?  it is hard to see things in the red and blue light.

here some photos of the set up and some plants grown exclusively under these lights.

the last photo shows two T-5 fixtures and a shop light on top for lily seedlings

Arnold/Rimmer - thanks for sharing your experiences of using fluoros and HIDs. Indoor growing under lights seems to be much more popular in the States than in the UK, thereagain we don't have to cope with such extreme winter temperatures! As you say, the various types of fluorescent lamps are much cheaper to run than halides/sodium lights and LEDs would be even more cost efficient (I'm starting to replace my house halogen downlighters with LEDS). As I suspected though, it's the start-up costs of an LED set-up that's the killer at the moment. Perhaps as they become more popular the prices may start to fall? They run much cooler than flouros and HIDs of course which is a bonus.

Returning to the subject of LED & other forms of lighting, I hope it will be useful to point out a large misunderstanding that has persisted for a long time. This is the belief that alpines and other plants grow more compactly in the wild than they often do in cultivation due to being exposed to higher levels of UV radiation. This is actually not true. In his bulb log last November http://www.srgc.org.uk/logs/logdir/2014Nov121415787177BULB_LOG_4614.pdf (http://www.srgc.org.uk/logs/logdir/2014Nov121415787177BULB_LOG_4614.pdf) Ian showed the new LED system that Gothenburg is trialling and said that they were "high in UV" for healthy growth. If you check the spectrum of the lamps used on the company's website, you will see that actually these lamps cover the range of 400nm to 735nm  - which encompasses the photosynthetic spectrum but not the UV. In fact these lamps don't give out any UV light at all.

Science does not yet fully understand all the ins and outs of the specific effects of various wavelengths of light on growth, but experiments on alpines have shown that levels of UV light do not affect the stature of the plants. In fact, like most things, UV can damage plant tissue just as it can damage your skin if you stay out in the sun too long. Experiments show that most plants actually reflect the majority of UV light that falls on them in order to protect themselves from damage. And the experiments also show that of all groups tested, Alpines reflect the most UV (more than 90%).

As well as experiments, observations in the wild also point to the fallacy of the idea that it is the UV keeping plants compact. For example, many arctic and sub Antarctic plants inhabit misty coastal ranges where they receive very little UV and yet they are extremely stunted and dwarfed. Also, if UV intensity had a significant effect, you would expect to see latitudinal gradients in the stature of alpine plants, but this does not occur.

So what does keep alpines dwarf and compact? While the full story may not yet be in, the evidence all points to LOW TEMPERATURE as the key factor. Our alpines in cultivation grow out of character largely because we cannot keep them cool enough. It is also known that the overall intensity of light (of all the useful wavelengths, but not UV) has a part to play at least for some species.

For those who would like to know the references and read more about this, the best place to start is the discussion about all this on pages 114 to 119 of the book "Alpine Plant Life - Functional Plant Ecology of High Mountain Ecosystems" (second edition) by Christian Korner ISBN 3-540-00347-0

Yes, I know that, Arnold , but  Ian's impression was that it was the higher levels of all  the spectrum of light, including UV,  that was the point of these  lights.  Either he got the wrong end of the stick as regards the description he was given, or he and the GBG folks are all labouring under a misapprehension!
Title: Re: South African Bulbs 2015
Post by: Paul Cumbleton on March 17, 2015, 12:22:30 PM
Hi Maggi,
The lights at Gothenburg would still be useful for increasing the day length (especially in their northerly latitude) and the overall light intensity the plants receive and these should lead to improved growth. The operating costs should also be cheaper than traditional grow lights. I would imagine that these are the reasons they are trialling them. Though the 'myth' that UV improves compactness is so ingrained that it would not be a surprise if they were also under that misapprehension.

I think it's because South African soil is low in phosphates and the thinking therefore is that bulbs from that region are sensitive to the phosphate content in plant food/fertilizer. So ideally they should be fed with a no/low % P content fertiliser. Personally, I just use tomato food at 1/4 to 1/2 strength and haven't had any major problems apart from some minor leaf burn when I've made the solution too strong. It may be that a no P fertilizer regime is better, and I think Paul C does so for his South African bulbs? They're presumably a candidate for Ian Y's policy of a tsp of potash per pot in March/April...
Title: Re: South African Bulbs 2015
Post by: Paul Cumbleton on March 18, 2015, 06:55:29 AM
Yes, the "low phosphate" regime was originally recommended to me by Gordon Summerfield based as Steve said on the low phosphate levels most of them experience in habitat. I actually use a 13 - 5 - 20 formulation, so low but not zero phosphate and this seems to work fine applied at half strength.

Thanks Steve and Paul. I think they received an accidental dose of balanced feed when I was watering some young bulb seedlings, so looking a bit yellow at the moment. Hopefully they'll recover. My usual feeding regime is to use JI#3 in the potting mix (1 part in 3 or 4 parts total) and a dose of sulphate of potash once or twice in the spring so I'll keep them to this. Cheers.

I think wind has a lot to do with compactness.  3 things come to mind from trying to take photos of plants on mountain tops. - bright light, constant wind, and cold (and often fog).

i would think that these things naturally select what lives and dies in the Alpine environment. so a different environmental without these things would yield different survivors/ thrivers.

But I was looking forward to a yellow blue flowers, unfortunately white was not the right colour. But that is the way it is. There is always a suprise in growing plants from seed. Nevertheless I will grow this plant in future - looking forward to the second plant´s blossom colour white or yellow/blue.

I suppose that's conditioned by the time they started to get their first watering. In my case it's usually this time of year, or maybe a couple of weeks earlier, before I have enough space for the Summer flowering bulbs in the greenhouse and I don't start to water until that happens. According to my old picture files it has usually been July before Albuca shawii has been good enough to picture. Try searching the Forum.

I'd also be interested to hear how people treat these seedlings in the early years. I'd have thought that if first-year seedlings kept bone dry over summer survive OK then the larger, second-year bulbs would be equally fine under this regime?

This must be the right place for asking a question about Veltheimia bracteata seedlings.  I have sown seeds last year in fall, and they germinated very well.  In May I stopped watering them with the intention to resume watering in September.  However, not only have they kept their first leave untill now, but they all start pulling up a new leave now.  So, should I start watering then again from now on or not ?  I read somewhere that the best way to loose these plants is when they are not kept bone dry over summer.

Thanks for your advice !

Hi Chris,
I wouldn't worry about your plant's reluctance to die down in summer. V. bracteata in my experience is almost evergreen and seems best with just a short dormancy of maybe two months or so in the autumn/early winter. Even then it may not lose its leaves.

Cheers

I can't speak for Ruben but we grew this unprotected in a crevice between rocks on the rock garden for a number of years and it seemed quite happy with our wet Lancashire winters in such a position. It's eventual demise was (I suspect) due to rodents rather than climate.

I grow flanaginii in open ground. We have wet winters and sometimes wet summers but this ones grows well in sandy soil for 4 years now! I don't gave winter or summer cover. Use a lot of grit in the soil, it likes good drainage but also lot of water in the growing period.

I appreciate the information. I may be that I have been keeping the bulbs too dry during the winter. The drain has always been excellent.

I think mine aborted its flowers last summer because of being too dry. Just received some seeds from Seeds by Post, South Africa (http://seedsbypostafrica.wordpress.com/ (http://seedsbypostafrica.wordpress.com/)), including Daubenya aurea, Empodium namaquensis and Nerine filifolia. I'm assuming it is best to sow them straight away?

Gethyllis villosa, first flowers in a potful of seedlings from Silverhill seeds sown June 2012. Much faster to reach flowering than I had anticipated. The two flowers are from separate bulbs and have done exactly as usual for the genus - both appeared simultaneously on the same day last week in (presumably) response to the weather turning a bit cooler and/or barometric pressure dropping.

Title: Re: South African Bulbs 2015
Post by: Maggi Young on July 30, 2015, 11:40:38 AM
Must say Darren, that I would have been pleasantly surprised  by getting flowers in three years too. Seems very generous of some bulbs to act at speed when some take "forever" !

I like the pink flush from the centre of  the flowers - is that typical?
Title: Re: South African Bulbs 2015
Post by: Darren on July 30, 2015, 01:12:51 PM
The pink flush does seem typical but variable looking at some pictures from elsewhere - you can see the intensity differs between my two clones as well.

I was shocked at the speed - many Amaryllids are notoriously slow. Though Haemanthus humilis hirsutus also managed it in 3 years for me.

You might have noticed the substrate. This is a moler based cat litter (Tesco low dust light weight to be exact) much used by the cactus growers these days. Behaves much like Seramis but is considerably cheaper.

I mention this because I believe it contributed to the speed with which the Gethyllis reached flowering size. Because of its porosity and structure it dries quite quickly and also encourages the plant to develop a strong root system. Gethyllis I've found prone to rotting in a 'soil' substrate but love this stuff. Most importantly it allows more frequent watering and therefore liquid feeding than a soil substrate which retains a lot of water.

 I continue to experiment with using this. Paul Cumbleton's findings with Seramis and fritillaria were that it grows bulbs well and massively reduces the repotting chores associated with more organic substrates that decompose - provided the feeding regime (including trace elements) is suitable. I have found with seedlings that in warm summers it can easily over-dessicate small seedling bulbs when dry so I modify it for seed sowing with a little composted bark.

One of the findings of Susan's college experiment with the stuff was that, used pure, it even kills Sedum by drying them out via the roots if allowed to get really dry under glass. Simply adding 25 percent 'compost' prevented this effect.

Hi Darren, did you use straight cat littler or mix it with the 25% organics for Gethyllis?
when do you start to water these? after your see growth or?

Post by: Darren on July 30, 2015, 03:47:41 PM
Hi Rimmer - The seeds were sown in a mix with 25% organics but after their first year they were moved into a much less organic mix - maybe 10% organics at most. I can just see a few flakes of bark on the surface in the picture. Watering starts early September with the other Cape bulbs.

Very nice, Darren.

The Gethyllis genus is new to me, but I was surprised to note it in flower so early. Reading up, it would appear to flower much earlier than other members of the genus. I would have been tempted to start watering as soon as the flowers appeared, but waiting till autumn presumably mimics the natural season in South Africa.

Thanks Angie & Chris,

I noticed yesterday that another seedling in the pot has put up a flower bud. Still bone dry and will stay that way for a few weeks yet.

Some more South Africans - opposite ends of the spectrum with regards attractiveness:

Wurmbea sp (LEG203?) This was from AGS seed listed with this collection number in 2006 2010. I did once ask on the forum if anyone knew anything about it but got no reply. I'm guessing it is from Lesotho and is summer growing. The second picture has my finger nail for scale!

Then there is Haemanthus humilis hirsutus. The pot had 5 flower spikes last year (all from separate bulbs/clones) and set loads of seed, which may have discouraged it from flowering so well this year. Or maybe it just wants repotting. This is getting a little water now as it starts showing leaves.

I grow ornamental Romuleas too. So far none of them have turned out to be a thug, however I have not grown R. rosea either. By what means is R. rosea a pest? Seed? Bulb division? All of the above?

Hi Robert,
Mostly seed - I think most seedpods contain a few dozen seeds which can persist in the ground for ages.
Considering it could only have come to Australia after white settlement it is amazing how it has spread around southern Australia. We have paddocks where there is more romulea than grass!

Thank you so much for the information. I have a batch of Moraeas that could go out in the garden soon. I think we could be a bit colder at our farm here in California. Most likely I will keep some back-ups in pots in case things go wrong out in the garden.

Gladiolus gracilis is certainly one of my favorite glads, with an amazing scent too. I encountered a small group of them growing in an abandoned wheat field recently - most of the flowers displayed unusual colours ranging from greyish-pink to bright blue.

This one (G. tristis?) I spotted nodding beside our dam yesterday, in the early morning light.
Title: Re: South African Bulbs 2015
Post by: Darren on September 24, 2015, 03:23:25 PM
Could the latter be a pale G. liliaceous, Rogan? This species is also night-scented and moth pollinated and flowers a bit earlier than G. tristis.

Have a look later in the day and see if the colour changes. That said - it doesn't look quite right for liliaceous - the segments are often wavy-edged which isn't present in your specimen. The back of the lower flower suggests the colour is there in a speckled pattern, which would be right for liliaceous.

Either way it is a lovely gladdy.

Hi Maggi,
I think it's mostly vegetative but it does set seed so some are probably seedlings.

My favourite Pelargonium is the evening scented Pelargonium triste which flowers in spring if we don't get a late frost! It is geophytic so I presume it could be shown here,

I am rather busy at the moment and not really equipped to make edits to the threads to show which are summer or winter flowering species  and a geographical  thread may not help with that distinction - but it might be more useful if instead of making a split, those of you who regularly post here, would  ..a) be sure to add a line to your signature box to say where you live - northern or southern hemisphere - and also state whether the plants you have posted about are summer or winter  growing. Presumably those of you growing these plants over time are aware of that?

 Perhaps some of you experienced growers might like to make a useful list of winter versus summer growers to post ??

 Meantime I'll rejoin this  thread  to the  previous one.

I look forward to this time of the year when Lachenalia nervosa (syn. L. latifolia) blooms; its sweet-scented flowers can fill a room with fragrance if brought indoors in a pot.

The hills are alive with thousands of Moraea bellendenii flowers at the moment. This is a slender Moraea that looks good in the garden if planted en masse.

Rogan,

I enjoy seeing your native flora. For me very  8) .

If I understand correctly the photographs are from your local area, i.e. zone 10ish and summer dry (i.e. no rain during the summer like most of California)?

What are the summertime maximum temperatures in your area? Coastal California can be very lacking in rainfall during the summer but the summertime fog from the ocean keeps temperatures very cool, and things somewhat moist (kind a' like parts of Coastal Chile) compared to inland areas like where we live where it can get very hot. Maybe South Africa has a similar weather situation near where you live?

As a matter of  interest - following discussion of these plants in the AGS Harlow Carr show thread....

Quoting from Motomu Nagaoka on Facebook - alongside photos of  Polyxena/Lachenalia  - pygmaea, ensifolia and longituba --------

"subgenus Polyxena another 3 species

I quote the part of the key table about these 3 species below as same as last raised."


  Key to the species of subgenus Polyxena

1a Perianth tube 12-27 mm long ......................................2
1b Perianth tube 3-8 mm long ..........................................4
2a Style 24-36 mm long; filaments well exerted; flowers almond-scented; seeds globose ......................................................................L. pygmaea
2b Style 11-20 mm long; filaments included to shortly exerted; flowers spicy sweet-scented; seeds ovoid ....................................3
3a Perianth tube subterranean; outer tepals 4-5 mm wide ...L. longituba
3b Perianth tube aerial; outer tepals 2-3 mm wide ................L. ensifolia

My guess is P. ensifolia - but it's just a guess - you're in a better position to make measurements etc, Rimmer ....  in another FB post, Motomu Nagaoka quotes this ( automatic translation, so a bit  idiosyncratic!)

"The following is about polyxena ensifolia.

First of all,-bear air differences, but the pivot bear air flowers (style) is 24-36 mm length is for, p. Ensifolia and p. Longituba is length 11-20 mm. And then, Pivot Bear Air's seed is round (Globose) for, the latter of the two egg-shaped. P. Ensifolia and p. Longituba key difference of the flowers, and the latter is when the land of the present, p. Ensifolia flowers is far from the ground, and they have a tip of the axis.

 I write in pygmaea from the history, p. Ensifolia is p. Pygmaea and  these can be confused.

In addition, this species is also variants, sub-species  Polyxena ensifolia subsp. Ensifolia and p. Ensifolia Subsp. Maughanii. Standard Sub-species is a long of three books and the 内花 (all the bull and to all the flowers) is a cylinder to jut out from subsp. Maughanii is the flowers in the cylinder to fit. "   !!

 It would be much easier to   get the Duncan book and read it in English.

Arnold/Rimmer - thanks for sharing your experiences of using fluoros and HIDs. Indoor growing under lights seems to be much more popular in the States than in the UK, thereagain we don't have to cope with such extreme winter temperatures! As you say, the various types of fluorescent lamps are much cheaper to run than halides/sodium lights and LEDs would be even more cost efficient (I'm starting to replace my house halogen downlighters with LEDS). As I suspected though, it's the start-up costs of an LED set-up that's the killer at the moment. Perhaps as they become more popular the prices may start to fall? They run much cooler than flouros and HIDs of course which is a bonus.

 am hoping to switch to using LED lights for propagation-does anyone have experience to share in this regard
