I grew Allium atroviolaceum about 6 years ago, perhaps in too wet a spot, as
it only persisted 3-4 years, then died out. It grew to nearly 5' (150 cm)
tall, much taller than the height you specify (and as specified by some books),
but checking Flora Iranica and Brian Mathew's "A Review of Allium section
Allium", it is indeed listed as occasionally getting as tall as 150 cm. It's a
slender plant, with a largish drumstick of dark reddish purple at the top, having
a most pleasing appearance.
I haven't grown Allium commutatum, although I've read much about it. It's
allied to Allium ampeloprasum (considered the ancestor to the leek) and Allium
porrum (the leek). The height range on this one is given to be 50-180 cm, thus
able to be quite tall. There are good photos of both species in the Brian
Mathews publication.
I find it interesting too, that a number of Mediterranean Allium species are
so late flowered (late summer to autumn) including Allium callimischon (and
varieties), A. cupanii, A. autumnale, Allium ericetorum, and others.
Thanks Angelo for the notes on some rarely seen Allium species.
