Hi Carrie, it's these - in the link

I planted these 2 autumns ago but the maroon ones - atropurpureum - didn't lastt beyond the first season . The whites are probably A. stipitatum - which are more vigorous

Here is a link that might be useful: alllium

Thank you, Paula. My experience with the ornamental alliums here is that most of them last a year or so and then peter out. It'll be fun to see them this spring, and they were cheap enough that I'll be happy with whatever I get. Thanks again.

If you want some vigorous Alliums, try 'Globemaster', 'Purple Sensation', 'Ivory Queen'(a short one)or A. Sphaerocephalon. 'Globemaster' does not seed itself because it is a hybrid of two different species, but the others all seed around a little too much in my garden. Of all these, 'Globemaster' is my favourite.

Thanks, ontnative - I have quite a few Purple Sensation & I love them. The "Raspberry & Cream" mix (and the 'Gladiator') were on such clearance that I couldn't resist giving them a try - even if they turn out to be annual in my garden.
