Thank you Alessandro :D
your plant is really fine !

Hans, another fine collection. Your Cyrtanthus mackenii 'cream' ex PT is my favorite. Nice to have something flowering this time of year.
Thanks for sharing. Looking forward to seeing some more of your wonderful plants in flower this year.
Angie :)
-
Thank you Angie :)
Please send me a bit sun and warm from Scotland ...so maybe more flowers will open
Hans

Hans, we have just been really lucky this winter. You might be having a cold winter but at least you know you will get a warm summer. Our summers are sometimes not worth calling summer.
Angie :)

new flowers from today :
Cyrtanthus mackenii "Himalyan Pink"
Cyrtanthus mackenii "Yellow Clarion" ( from a nice forum member ) ;)

Hans - What a lovely range of colours in your various Cyrtanthus. I have to wonder how you treat these. I ask because I repotted a Cyrtanthus brachyscyphus into a 50cm pot one year ago, it grew very (too) vigorously and flowered heavily throughout the late winter and was still giving a reasonable show in late autumn. Now it is in a greenhouse, badly congested and with only a few flower stalks. The largest bulbs are not leafing out and sit atop the soil.
Seems that what I once thought a slow and deliberate plant with liuttle increase for quite a number of years has suddenly become a thug of sorts.
I wonder if the larger bulbs are not getting senescent. Should I toss the larger bulbs or pot them on singly? Do you have to divide and repot every year? If so I will have to find homes for quite an excess.
johnw - +3c and rain
-
Many thanks John :)
I believe I have now found the secret with those evergreen Cyrtanthus ....I gave them all two week a little water !
I do not repot year my Cyrtanthus - only if the pot is really to small.
Good luck
Hans
-
Hans your Cyrtanthus Himalyan pink is really nice 8), such a nice shade.
Angie :)
-
:D :D :D
-
John,
mackenii, obrienii, brachscyphus, and some others enjoy being repotted every other year here in a warm zone 6 (east Tennessee). All flower in the winter for me, Dec-Feb. I find the older bulbs tend to stop flowering so much. Maybe in cultivation they are short lived. I find they flower best when given a short dry dormancy, but they grow fine in standing water also!
Nice "Yellow Clarion" Hans ;D Mine is in flower now as well.

wunderbar Hans... ;D

Beautiful Cyrts, Hans. I'm glad the cream has done well for you and is flowering. The most reliable flowerer of those I have here. The 'Himalayan Pink' is a great colour. Such a good "pink" as opposed to the peachy colours you see in some of the pics. I'm not sure I've seen such a clean pink before. Are you going to cross them all and see what other colours you can come up with? I've finally identified for sure the good yellow that I have been trying to send you, but I think your 'Yellow Clarion' is at least as good, probably better than my unnamed one.
-
Many thanks Paul !
No - I have not cross it ....but maybe the bees ?
I'm glad that your minds have a bit changed and you looking again pictures and postings ...a good way !
All the best
Hans

Hans,
Thanks. Yes, starting to wander the forum a bit more now.
Good luck with seeds from the Cyrtanthus... it will be interesting to see what results you end up with in the future. 8)

Very nice Hans, you certainly can grow these well.
Angie :)

:D :D :D
Thank you
Hans

An unknown.
-
Arnold,
It could be a hybrid. I've had a complex flowering for me for the last few years, which has some resemblance to yours, at least partly. I must prepare some pics of my hybrid again for this year.... now 3 different colours have appeared, which I am very pleased with. Is your multiplying much?
-
Paul:
Mine multiplies vigorously. I think I've sent one or two batches to the PBS BX/SX.
-
Excellent, Arnold. Good that it is offsetting so well. Always more flowers that way. ;D Mine are just starting to get to the size for multiplying, but they are fairly slow I think. I figure if they're big enough to flower, they would be multiplying rapidly by now if they were going to. Could be my conditions as well, of course.
-
today is flowering a nice Cyrtanthus hybrid received from a friend in AU ( thank you Paul ) ;D
Cyrtanthus X "Red Prince"
enjoy
Hans

today another flower :
Cyrtanthus "Stormy Sky"

today another flower :
Cyrtanthus "Stormy Sky"
Such a lovely flower. I wonder why someone would call it Stormy Sky ::) It looks so delicate.

Angie ,
like you I also not understand why the breeder has give this name ...anyway it is a nice plant !

Here finished almost flowering
Cyrtanthus breviflorus
start flowering
Cyrtanthus brachyschyphus
and Cyrtanthus brachysiphon
Roland

here flowers of
Cyrtanthus spiralis

today is flowering :D
Cyrtanthus montanus
the diameter of the umbel is 15 cm
-
Hans, which species are involved in the hybrid Red Prince?
I've always understood that C. 'Red Prince' is a one of the progeny of what were considered to be bi-generic hybrids of Vallota purpurea and various smaller Cyrtanthus. These crossings were carried out both in New Zealand and California in the late 1950's and early 1960's. The Vallota is of course now Cyrtanthus elatus so Red Prince should be considered a hybrid of two Cyrtanthus species, probably C. elatus x C. mackenii.
-
C. 'Red Prince' has indeed been called a C. mackenii hybrid previously in the Forum:

Hans,
That Cyrtanthus spiralis is gorgeous, both the flowers and the cool leaves. How big and the flowers and the leaves? It's hard to tell from the pic.
Congratulations on the Cyrtanthus montanus..... I've grown that species for years and never managed to flower it yet, but hopefully one day. I managed to finally flower Cyrtanthus falcatus, which is the same age as my montanus, so hopefully it might be a bit more co-operative this year. ;D
Roland,
You've positively got a brevi of beauties there. I'd never noticed there were so many of the species starting with brevi. :-\
Thanks for the pics everyone.
-
Fantastic plants Hans
I like the leaves from the C. spiralis
Roland
-
Paul ,
I'm glad that you like it
To your question about C. spiralis :
the stem has a length of 30 cm
the diameter of the umber is 13 cm
the lenght of a flower is 7cm
the leaves are 1,2 cm broad
I dont know why so many people have problems with this plant - they grows well for me and I have near every year a flower ...maybe it is a good clone ?
-
Thank you Roland !
my compliment to your C. breviflorus ...I have really problems with this plant
Which conditions have your plants ?
-
only a try :
knows maybe anybody here ( from the northern hemisphere ) a source for a Cyrtanthus flanaganii bulb ?
It is possibly to buy seeds from the southern hemishere ....but it makes no sense to buy it now and sow it in our spring
Maybe anybody has surplus seedlings ( more than one year old )
Please send me a PM
Hans
-
Cyrtanthus obliquus, the only bulb of my batch of obliquus to bloom so far. This one has 6 leaves; the others all have only 4 or fewer leaves.

Hans J, congratulations, your flowers are always amazing!!!!! You know it, righ? 8)
I'm also making with a beatiful Cyrtanthus collection, but they are still seddlings or little plants, maybe one day I can also show here their flowers :D
Hi George, nice to see you here :)

another Cyrtanthus flower is open today ( flowering for the first time in my collection ):
Cyrtanthus sanguineus f .glaucophyllus
Hans 8)
-
Very nice Hans, lovely colour.
-
Can you tell me when do you start to fertilize your Cyrtnathus seedlings? Mine have almost two mounths and until now i did not aplied any fertilization...
I've the C. clavatus, it's a very little plant, the seedlings are deminute and I'm afraid to damage them.
And, by the way, wich is the ideal fertilizer? Ochids fertilizer, with half of the mesure?
-
Lovely pic, Hans. I missed it before now. I can now see where the shape originates of the hybrid seedling I have that involve sanguineus.
I'll be interested to hear the response to Cris' question myself, as I am very, very poor at fertilising seedlings, which is why all my seedlings tend to take so long to flower for me (not just Cyrtanthus here)..... well that and the fact I seldom repot them. Knowing what fertilisers people use would definitely be useful.
-
Paul ,
thank you :D
To the fertilizer question :
I use since 2 years Phostrogen and I'm very satisfied with the results - for seedlings I use the half dilution .
In case you can not get Phostrogen so you can also use fertilizer for Tomatoes - importent is the high Kalium part.
Orchid fertilizer is in my eyes not so well - the formula is different
Hans
-
Hans,
I had to go and look that up. I'd never heard of Kalium before (or if I have, I've forgotten it), and didn't realise that it was the latin name for Potassium. Obviously the reason for the K in NPK. You learn something new every day. 8)
-
;D ;D ;D

Yes, "Kalium" is the German/Latin name for Potassium. N = nitrogen and P = phosphorus.
A good general, soluble, fertilizer for bulbs is N-P-K 20-10-20. I suggest using continuous liquid feeding (i.e., have fertilizer in the water every time you water) with Nitrogen (N) at 100 ppm. This should not burn seedlings.
"100 ppm" is 100 milligrams N per liter of water. For a 20% N fertilizer, one would use 500 mg or 0.5 gram of solid, dry fertilizer per liter of water. I got this instruction from some experts over the years, and it's what I try to use most of the time.

That said, my seedlings of C. clavatus are down to only a very few plants left, and they seem not to be growing. They tend to lose their leaves in summer, where their pot sits outdoors in full sun and whatever rain we get -- not much this past summer.
With clavatus and epiphyticus, there was a quick loss of most the the seedlings that germinated, then the few survivors have tended to hang on a long time but not grow large enough to bloom. My conditions are just barely marginal for both these species, it would seem.
Jim
-
Jim,
So can you buy just Nitrogen fertiliser? I'm trying to think whether I've ever seen anything here that is just Nitrogen? There are various Nitrate fertilisers, but they are something-or-other nitrate. I've never thought about a pure nitrogen fertilier in this way before. :-\

Paul,
I use a soluble fertilizer, 20-10-20 with micronutrients. You can get pure "nitrogen" in fertilizer (i.e., no phosphate and no potassium) by using things like ammonium sulfate, ammonium nitrate, sodium, calcium, or magnesium nitrate, etc. Some people do use such things, for specific purposes; farmers use liquid ammonia on their fields, for instance. For growing bulbs, we need to have a reasonable balance of N, P, and K. For most bulbs, I suspect a very good balance would be 20-5-15, since that tends to reflect the elemental composition of most bulbs. I can get 20-10-20 readily, so that's what I use.
For Nerine, I tend to use a nitrogen-free mix based on potassium phosphates and potassium sulfate, which ends up being about 0-15-35 more or less. That is the only exception I can think of to the balanced feeding rule. Even the Nerine need a little nitrogen, of course, but a normal nitrogen feeding tends to induce virus-like symptoms in some of the broad-leaf Nerine species and hybrids.
Jim
-
Thanks Jim.
Very interesting comment re the Nerine leaves. Do you think it is causing the exhibition of underlying virus, or causing leaf distortion that mimic virus symptoms?
-
Thanks Jim.

Sir Peter Smithers thought the higher nitrogen levels released a latent virus carried in the broad-leaf nerines' DNA. Several other experts scoffed at the virus idea. Nevertheless, growing bowdenii or sarniensis with normal nitrogen levels in fertilizers seems not to be good for them. I actually tested the idea, and got plants with mottled and distorted leaves.
Jim

Absolutely fascinating. Thanks for the info.

Jim Sir Peter Smithers was a very forward thinking chap because i am convinced his theory is right but not just Nerines as with all plants and as part of a plants evolution viruses are entwind. I hope that makes sense.But i just can't imagine everybody burning or binning there plants and when a plant lives with it comfortably that's why they laughed(see no evil :P
-
Jim - I have to agree. In the early days I did give my nerines regular feedings and saw virus-like streaking. In a letter Sir Peter warned me and I reduced the N to about 1/8 strength once or twice a year and the symptoms disappeared. Can't blame aphids or other insects for virus transmission as I've never seen a bug on them. Now the get mainly P & K 1/4 strength 3 to 4 times. Amazing how they tolerate nearly sterile mixes of peat, gravel, sand and a bit iof leafmold for years.
johnw
-
...the problem seems for me to find a fertilizer without N ....here in Germany is it not aviable :-\
-
Hans, I make my own. Get, from a chemical supply house, KH2PO4 (i.e., monobasic potassium phosphate), K2HPO4 (dibasic potassium phosphate), and K2SO4 (potassium sulfate). They do tend to be expensive in chemical reagent grade. You might try getting them (in relatively huge amounts) from agricultural suppliers; these compounds do make good fertilizer, after all.
Mix thoroughly one part (by weight) KH2PO4, one part K2HPO4, and 2 parts K2SO4. This gives something in the range of N-P-K 0-15-35 (more or less).
You could make these sorts of fertilizers from sodium phosphates and potassium chloride, which are cheaper; but when mixed they produce an equal amount of sodium chloride. Cheap fertilizers likely are made just this way in commerce.

Jim -thank you for your advices
I have in menatime found "Thomaskali":

Could you please look if that would work ...I'm not shure because there is a lot of Calcium Oxid ( 20%)
I dont know if this is well for bulb plants ...
Thank you in advance

Hans,
That fertilizer looks OK for nitrogen-free feeding. It does not actually contain CaO (calcium oxide) which is very strongly alkaline. It does have other basic (alkaline-reacting) materials, probably calcium carbonate, so watch the pH of any soil you add it to for gradual changes. Bulbs do indeed need substantial amounts of calcium and magnesium besides the N, P, and K.
In cases like this where one is using a new (to them) material, use cautiously, first only on a few sample plants, until it can be seen that it does not cause any harm.
Jim
-
Thank you Jim ,
If I use this PK fertilizer would be 1 gram per liter OK ? ( 8% P + 15% K )
On the description is only 80-100gram per m2 written ...
I'm on the right track ?
Hans
-
Hans,
Yes, you are on the right track. If this material is soluble, then about 1.0 to 1.2 grams per liter of water would be right.
Jim
-
Jim - thanks !
I have now made a solution to test if it is well soluble ...

Cyrtanthus eucallis in bloom in the greenhouse today.
Jim

Jim, is it correctly labelled? ::) it look like C. sanguineus to me
-

Angelo, that is a very good point, and I'm not at all sure. It came from another hobbyist, so the ID is open to question.
Jim
-
Nice Cyrtanthus there Jim. Very nice labels too, do you get them from Yucca Du?
johnw
-
Thanks, John.
I do the labels myself using zinc markers (in the trade) and a Brother P-Touch label maker on TZ laminated (UV-resistant) tape.
I get the 10-inch tall markers from A.M. Leonard, but other suppliers have them too.
Jim
-
OK, I looked up eucallis and sanguineus in the 1984 booklet, "A Review of the Southern African Species of Cyrtanthus" by Reid and Dyer. The flower I have is sanguineus.
Sanguineus: larger flower, petals recurved, single bloom in umbel.
Eucallis: smaller flower, not recurved, up to 6 flowers in the umbel.
So perhaps I now have a second clone of sanguineus and can try to produce seeds of this species in the future. Meanwhile, does anyone know where I can get seeds or a bulb of eucallis?
Jim
-
It looks if my C. eucalis makes a baby Jim
help me remember in a few months
Roland

I received this two bulbs a few weeks ago and I'm so surprised as they are already sprouting their leaves, and more, how the leaves just start to get the spiral form when they appear :D
