Allium 2018

[Maggi Young]

Nice, Yann - what is the plant in the background, please?

[Rimmer de Vries]

Caloscordum neriniflorum Codonoprasum nerinifolium from Siberia. I cannot find anything on the internet about this wonderful late blooming allium

[Leucogenes]

Wow... what a graceful beauty. A beautiful spectrum of colours and a great shape of each flower. My admiration...Rimmer.

How tall is this plant?

How tall is this plant?
Thomas

Flower stems are 8-10”. (22-24cm) tall. Flower umbels are 3-4” across.

Thanks for the info...Rimmer. A truly majestic allium. I've never seen it before.

No such thing as Cododoprasum nerinifolium.  On a genus level, it's a confusion from the 1800s, Codonoprasum is a Section of the genus Allium, but even here, neriniflorum (not nerinifolium) was never part of.  This Chinese outlier of the genus Allium, is Caloscordum neriniflorum. Unfortunately distinct Allium allies (like the more familiar Nectaroscordum, a valid genus in my book) have been absorbed into Allium, and so too the monotypic genus Caloscordum neriniflorum has been absorbed into genus Allium. It's a cute hardy perennial in USDA Zone 5, must get it again... the morphology of the plant is unique and different than Allium, but it gets lumped into Allium anyway.

Allium chamaemoly is in flower again - easy to miss if you're not keeping an eye out for it!
Grown from seed from AGS Sdx 2005 collected in France, I think

Allium wallichii.  Amazing number of hoverflies on the flowers.

[John85]

What is the name of this allium?
It is sterile so I guess it is a hybrid.
It is flowering now.

[ashley]

It looks to me like what forumist Mark McDonough calls 'Allium senescens glaucum of Hort'.

[John85]

Thank you Asley
I suspected it was related to A. senescens because of the flowering period but the foliage is not at all "glaucum" but green.

Allium incensiodorum, a species from Croatia. it's a late bloomer and it has triangular stems and strap-like leaves

[sokol]

Is it the same as Allium senescens montanum? I have seen it in Croatia last week and very few are already in flower at low levels.

Hello,
Can anyone help identify (what I assume to be) an Allium from the following pictures of plants with seeds, and a close up of the seedhead. They were growing on a slope which was covered with alpenrose at 2000 metres south-east of Lake Geneva (above the town of Bex to be precise). It looks like they had rather large leaves, so my first guess was Allium victorialis, but each flower stalk had 2 seeds whereas the only seed head picture I found on the internet had a single seed per flower.

Many thanks in advance for your suggestions.

Stefan, here's what i've found

However, S t e a r n
(1978) stated that the chromosome number could vary from 2n = 16, 24, 32, and in some
karyotypes the B-chromosomes (1-4) were described. The present investigation was addi­
tionally initiated by the work of R a d ić (1989) who described the populations from the Mt
Biokovo region investigated herein under the name A. incensiodorum. The plants in these
populations differ in certain morphological characteristics and in flowering time from the
original species, A. senescens ssp. montanum. In A. incensiodorum the pedicels are ribbed
and scabrid with papillae of very different sizes, the leaves are slightly ribbed and angular
above, and perianth is stellate, having segments with large pepillae especially on the keel
(R a d ić 1989). This onion flowers in the summer. In our work we used the name A.
senescens ssp. montanum despite the fact that G r e g o r y et al. (1998) in Alliorum Nomen-
caltor accepted the name A. incensiodorum proposed by R a d ić ( 1989) as a synonym.

i also grow Allium lusitanicum (ex senescens montanum) from Pyrénées and Alps, both have almost spheric umbels.
In the case of incensiodorum it's hemispheric, the plant is also shorter. But lusitanium is very variable and i've seen in the wild several population with hemispheric umbels. Simply add to the confusion!

Here's lusitanicum in my garden
