This species is a well established escape from cultivation here in
Sacramento, Ca. However it rarely achieves its characteristic triangular
stems unless given cultivated conditions and producing larger bulbs, so can
be a little tough to ID if you are looking for
that particular feature as a key.
I have never seen it set seed, in fact it seems incapable of such, spreading
instead by the mechanism of top set bulbils, not unlike
the cultivated forms of top setting garlic.
Does anyone out there understand the mechanism of why this is so, well
enough to explain it to me? I presume that this is some sort of adaptive
evolutionary response. Certainly it seems to have served
this Allium well in its quest to conquer the world.
Respectfully,
Michael Larmer
