Allium 2017

[WimB]

Allium dichlamydeum

[sokol]

The first thing to do when a plant flowers for the first time is to look whether the Name is correct. Unfortunately this is not the case too often.

Can anyone determine this Allium? It lookes similar to Allium egerovae shown bei Rimmer below.

Hard to tell, the plant might be in an immature first-flowering state, where one does not experience to true shape of the inflorescence.  Always helps to see the foliage and whole plant views too, for potential ID.

Allium lemonii a  california allium growing in Michigan sand bed, seed started fall 2015 out side in sand bed

Not Allium lemmonii (note spelling), looks like campanulatum, always has that "halo" coloration in the center of the flowers, and low stems.

Allium chloroanthum tall form
seed ex Ruksans

Don't think this is chloranthum (note spelling), looks more like a form of Allium flavum or flavum var. tauricum (or hybrid of those). Allium chloranthum is also yellow, usually a light yellow to greenish yellow, longer pedicels, and narrowly campanulate flowers.  The stocky very silvered stems point to a flavum var tauricum plant.

Allium scabriscapum
seed from Alan Edwards
start 2014

Note sure what you have here, but Allium scabriscapum is a very nice yellow-flowered species from Turkey, has full spherical heads of yellow. Here's a couple links:

I agree with Mark 100%.

In the wild the foliage of Allium campanulatum is generally withered at flowering time, however this is not always the case in cultivation. Plants in our Sacramento garden tend to retain their foliage while the plants are flowering. They still seem to prefer a dry rest during the summer. The flowers can be very pale in the wild, however good selections can be made that have flowers that are a deeper pink and look very nice (even in warm weather).

With a bit of practice the California Allium species can be keyed using the Jepson online manual. Occasionally unlikely hybrids occur in the wild. My experience has been that they are sterile, but then unexpected things happen all of the time.

Thanks Mark
i first asked for identity of the "Lemmonii" on this forum, but received no reply and and then found a similar planting elsewhere in the garden and guessed, badly.  L campanulatum is a possibility as i have tried seeds labelled as L. campanulatum many times never to get any results in our frozen winters.

The"chloranthum" is a very nice green yellow species. i have 2 forms, one from PC that is about 4-6 inches shorter than the one from Ruksans about 18-20" tall. 
This clump was grown from seed from the Ruksans form, the PC form has not made seeds for me.
these plants bloom here several weeks before Allium flavum. 
Also this plant is about 4-6" taller than Allium flavum.

The Allium scabriscapum ? showed up in front of a seedling label as from Alan Edwards in a garden seed bed. this area had many allium seed plantings that did nothing and many labels were removed after several years of nothing, this year this bloomed with the corresponding label but a good rain can relocate surface sown seeds easily.  it is a smaller dainty plant with a ~ 8" tall wirey glaucous stem.

Allium flavum is highly variable in stature, to dwarf forms as I'm sure you're aware, to low growing forms 6-8" tall, moderate growing forms up to 12-16", and very tall forms up to nearly 2'.  Accordingly, saying a plant is 4-6" taller than Allium flavum doesn't make much sense to me.  I recommend checking keys and original botanical descriptions to verify whether you're growing chloranthum or a flavum form, the plant shown looks like a flavum form.  I can post two photos of chloranthum that was sent to me by Arnis Seisums (approx. 13-14 years ago).

I am sure your are correct.
For me flavum flower buds has always emerged odley feom the leaves at strange angles

This one grows in a more onion normal way straight up
