Allium 2011

[wmel]

Need help with this one, received as Allium heldreichii

I think your a. heldreichii is correct ( if mine is correct to.......see photo)

Allium atroviolaceum is in flower the last 2 weeks, sown early 2007, seed from Sergey Banketov in the Caucasus:

Your allium atroviolaceum looks like allium erubescens, allium rotundum and allium jajlae I grow, but again I do not know if mine are correct

Looks like A. heldreichii to me

It is often easier to determine what something isn't versus what it actually is.  Stephen, I don't think what what you show as A. atroviolaceum is correct, but then again, I don't know what it is.  Weitse, your plant doesn't look like A. erubescens; perhaps more like Allium rotundum ssp. jajlae.

To give an impression of what Allium atroviolaceum looks like, I have uploaded a number of images from the Taxonomic Allium Reference Collection at IPK Gatersleben, with the fair use provision... don't forget, it's a terrific resource, although currently the site is showing an extreme slowness issue, and it takes 1-2 minutes for the image thumbnails to show up... all the more reason to sample a few images under fair use and post them here.  There are 48 records for Allium atroviolaceum on IPK, so lots to look at.  There were a few records that showed plants with variable color (some where greenish or nearly white with purple midveins, but most are a dark rosy purple and look rather similar).

Images 1-4 are closeups of Allium atroviolaceum, there is a distinctive look to the spherical head, with the filaments splayed outwards sideways once exserted from the flowers.  The buds are also distinct (Image #5, shows its close relationship with Allium ampeloprasum).

Image 6-7 show Allium erubescens, it has segments (tepals) that are "markedly outward-curved at the tips" (differing it from A. rotundum without such outward-curved tepals).  It has a unique stamen arrangement, looking like a sea anemone, with very broad cone-like bases to the stamens that 90 degree reflex and splay out horizontally.  It's a lovely species, wish I still had it.  Here again, both images are posted here under the fair use provision, the first from IPK Gatersleben, the second is a scan from Brian Mathew's "A review of Allium section Allium".

Advice needed from an 'Alliologist';

This morning I received plants of A. scabriscarpum originating from both Turkish and Iranian collections. They appear to be barely bulbous (a thick fibrous 'tunic' around a narrow bulb with a lot of obviously perennial roots). Although clearly summer-dormant they were packed dampish presumably to prevent the perennial roots drying out. My question is - will these plants stand a dry summer in a pot? My feeling is they would be better in a bulb frame with some moisture at depth, or even planted out in a dryish spot. Any advice?

Thanks very much Mark and Weitse! My ”atroviolaceum” has quite spherical heads about twice the diameter as Allium jajlae which is growing nearby (and long past flowering). I’m pretty sure that the buds were ampeloprasum-like but I’ll have to wait to next year to be sure. The leaves also look similar to the Gatersleben plants. Looking through the latter, they are quite varied in size of head and other details. In my plant (second picture the filaments are a bit splayed). It’s not unlike TAX1372 in the Gatersleben pictures, from Georgia. Mine is also from Georgia collected by Banketov, a botanist. So, I’m not convinced it’s not atroviolaceum. However, it could also be wishful thinking...

4 Allium this week in my garden:

Allium ovalifolium, flowers and foliage
Allum sp , seeds collected at 4100 meter in Sichuan 2005 by Jurasek.
Allium sp identified in this thread as possibly kunthianum karsianum
Allium sikkimense

4 Allium this week in my garden:

Allium ovalifolium, flowers and foliage
Allum forrestii , seeds collected at 4100 meter in Sichuan 2005 by Jurasek.
Allium sp identified in this thera as possibly kunthianum karsianum
Allium sikkimense

Magnar, you grow some of the best Alliums!  That's a very fine form of A. ovalifolium, but more than that, it looks to be A. ovalifolium var. leuconeurum, a variety distinct on account of the white leaf midvein.  Great looking leaves on that on.

I believe the one labeled as A. forrestii looks like it is actually a form of the variable A. sikkimense.

Thanks for the info.. Yes, when I check now I see the seeds have obviously been misidentified by Jurasek

just what I thought Mark

but it's a nice coloured clump

Stephen, it's such a beautiful form of A. wallichii. Now I'm impatient to see my petite seedlings grow up and flower.

[wmel]

No real summer in Holland, a lot of rain and most time teperatuur somewhere between 17 and 22 oC.
But ofcourse there are always alliums flowering.
I post some photos made today

a. tuberosum and a mini tuberosum form
a. lenkoranicum (late flowering one from seed)
a. spaerocephalon (round / late form)
a. backhousianum dry seeds
a. nutans (and some others in the picture)
a. schoenoprasum Album (second time flowering this year)
a. senescens montanum
a. senescens seedling

I've had this Allium for years and am still puzzled as to what it is. It came from a good friend who was gardener of the herb garden at Hardwick Hall near Chesterfield. It was growing in the herb garden and for all I know may still be there. It is very tall and slender and flowers in June. What do the experts think?

I think it's a very nice allium, but as I am not an expert, I have no idee what it can be.....
