Title: Acis/Leucojum 2017
Post by: fermi de Sousa on January 11, 2017, 02:18:45 PM
I was surprised to find these Acis autumnalis while weeding - and it looks like I missed the first couple of flowers.
It seems a bit early for the "Autumn Snowflake" as we're barely pass mid-summer, but this area has received some rain as well as the sprinkler!

Hi Wim,
nice to see your L. vernum forms, especially 'Null Punkte' - which I thought I'd never seen before but then remembered that I'd read about it last year!

I have forgotten to post pictures of my L.vernum's from last spring.
They flower here usually in late April. I haven't noticed differences in the flowering time of different kinds, but that is probably because winter lasts so long anyway, and I will have to pay more attention to this.

I got the first L.vernum about ten years ago, one bulb which came originally from Saaremaa, Estonia, where it has naturalized. A friend had a cottage there and she brought bulbs here from there. This type has only one flower in a stem (L.vernum var vernum?), and it has increased well here in these ten years, both from bulbs and from seeds, and I have divided the clump already a couple of times. In the second picture there is the original clump last May after flowering. These have green spots which turn to yellowish olive when the flower matures.

Another type is the one I got from an old lady in the market in Tallinn, Estonia, three bulbs in 2011, and also it increases well. It has mostly two flowers in a stem, and when they start flowering, the spots are green, but mostly turn yellow during flowering. I have been a little confused, because my plants don't stay the same colouring. Last spring I noticed the first seedlings around this clump, and I was glad to read from Wims article that different types come true from seeds. I divided this clump last summer. The third picture is from this type. I have to take better pictures of the flowers of all these this spring.

Then I have one clump which I had bought from Netherland. Also they have mostly two flowers in a stem and also they turn yellow during flowering.

The last picture is of L.vernum var carpathicum which I had bought from Janis Ruksans about then years ago. It has yellow spots right from the beginning of flowering, but it hasn't increased at all during this time. It may be because it grows in dryer spot below a plum tree, and every year I've been meaning to move it and then I forget it in the summer, and can't find it.
All my other Leucojums grow in more moist soil.

Leena, I'm not 100% convinced var. vernum and var. carpathicum should really be given varietal status, there is a gradual change of populations in the wild too...and some start green and turn yellow like yours (might be dependant on the weather and the soil too).

Is the carpathicum from Janis the cultivar Podpolozje? I see they have a double flower on one flower stalk. Also, don't worry. You can lift them now to transplant them (like Galanthus, in the green), just don't leave them out of the soil for too long!

Post by: Leena on February 20, 2017, 12:29:41 PM
Wim, in my notes I have only written L.vernum var carpathicum, and the year was 2007, so I don't know more. I will move them to more moist soil this year!
Most of my Leucojums grow in slightly acidic soil (because of Rhododendrons I haven't added lime), and increase well, but that must be because of the moisture. :) They seem to be so easy to grow and I love them. The only trouble was in the beginning where to get them, as they are not available here in Finland in garden centers.

Post by: Karaba on March 02, 2017, 03:09:58 PM
I've never looked at the color of the spot at the time I've seen wild population but I have a bulb from a wild population of Jura Mountain (France) and the spot are yellow, from the start of flowering. So, I really don't know what kind of taxonomical statu can be given to carpathicum...

I'm not 100% sure either...I think yellow and green tips can be seen in all populations, so those two varieties might not deserve varietal status.

Two months later and they are still flowering! Good value,eh?!
This clump is originally from Otto; I think he told me that they were sourced in Portugal.

Oh dear, already? Mind you, we had our first cyclamen hederifolium in flower on election day (8th June).  This was shortly after the heavy rain which broke 6 weeks of drought.
Let's hope these 2 early flowerings are not an early autumn....

After diner i've sweeped the greenhouse's floor and checking pots, i've seen the first sign of life. Acis are already in buds, will water tomorrow morning. Very early season, looks like the switch between summer and autumn gonna be quick.

I would be interested to know how members grow Acis autumnale in the garden. It has such delicate stems and flowers I have never tried other than in large pots. The only place I can recall is at Rosemoor, where it is/was grown under a large tree with very little competition. Thought about in my drive but it would be visually lost against the gravel.

Brian  - I tried Acis autumnale in the garden many times and they were invariably winter-killed the very first year.  Ken has tried them in his garden and they've all failed.  I gave up and settled on potted ones near an azalea bed in part sun; to our great surprise it self-sowed under a very prostrate azalea and now has made a sizeable clump which has wintered for at least 10-12 years.  It's just about to flower, part sun and a rather peaty ericaceous soil, not what I'd have expected to be a suitable site.  Oddly I've never seen other volunteers about.

Perhaps I should move the potted ones away from the volunteer and collect selfed seed.

It is the same here and they appeared rather fast, 10 days after repotting, when there was no sign of life.

Here I think they were triggered by a long dry and hot period finished by cooler weather and rainfall.

Here you can see the two places, where I grow Acis autumnalis in the garden. They're seedlings, sowed in January 2016 and planted out about one year ago. Until the flowers showed I had a brown plasic ring around the place in order not to disturb them. Now I placed flat stones around.
[attach=1]
These started flowering about four weeks ago and you can only see the rest.
[attach=2]
This place is underneath a Prunus cerasifera bush, aside a Paeonia tenuifolia and Phuopsis stylosa which estimate the dry place as well.

They have sun for about half a day (I pruned the Prunus up to a height of about 1 m). The leaves look as green as the grass on the other side and the Phuopsis. I'll see.
Thank you for the problem to watch.

I have repotted all my Acis autumnalis, most bulbs had roots in July despite a long dry period. Today I had the first flower of plants sown 2 years ago. They are in light shadow all day long plunged in a sand bed. Also Acis rosea did flower there and stayed green till now. Both are unprotected outside throughout the whole year.

Hi sokol,
it's definitely L. aestivum 'Gravetye Giant'. The ordinary L. aestivum is also in flower - I should get a pic of the two together for comparison :)
I've grown L. vernalis and they don't like my climate :'(  though Otto does well with it in the Dandenongs.

Hi all ,

here are two pics of Acis ionica
Grown from seeds from my trip in year 2010 on Kephallonia

The location where I have found was interesting :
They have grown near a pass inside the island – the altitude was 650 m !

This is very unusul – because all other locations of Acis ionica which I have seen on Zakinthos / Kephallonia was always in lower altitude
Zakinthos : 70 m
Kephallonia 5 m ( sea side )

In the first description of  Acis ionica (BAREKA, KAMARI &  PHITOSis ) written :
"Habitat and ecology. – Open, calcareous, stony and rocky places, hill slopes generally not far
away from the coastline and often facing the sea, usually in phrygana or low macchia communities,
at an altitude of 3-350(-450) m"

So it seems I have found a really new population from higher altitude …

Have fun
Hans

I was given more than a dozen bulbs of Gravetye Giant and I planted them all over in different places.  This is the only one that still survived after two years, and it has continued well.  I suspect I am at the border of cold hardiness for it.  Anyway, I show it just to confirm that Fermi's does look like Gravetye Giant.  BTW, it is giant!
