Starring in the rock garden in early December is the amazing Allium virgunculae ‘Alba’. This delightful dwarf allium to 8″ tall is similar to the better known and slower offsetting Japanese Allium thunbergii. Allium virgunculae, which typically has lavender flowers, hails from Japan’s far south Kyushu Island.
We’ve got some really superb unyaaw’s blooming now. Actually, if you’re not of the Cajun persuasion, they’re onions…of the genus Allium. The North American native Allium canadense is quite showy in the late spring/early summer garden. The first is a superbly dense flowering selection, Allium ‘White Flag’, made by the late bulb guru, Thad Howard. Allium canadense var. lavendularae is a lovely purple-flowered form. Purple seedlings pop up occasionally in wild populations, but we’ve been able to isolate a particularly nice purple form from light lavender flowering plants that originated in Kansas, shared by plantsman Aaron Floden.
Allium ‘Ostara’ is a new bulbous ornamental onion from a cross of the lovely, but difficult to grow (in the southeast US) Allium karataviense and Allium atropurpureum. We’re growing this in our crevice garden, which is working well…so far. We’re hoping the genes from Allium atropurpureum will make this more growable.
Although it’s a bit late, we wanted to share a new image we took of Allium kiiense in the gardens last fall. For us, this is one of the best small alliums for the garden, but because it flowers so late in the year (2nd week of November for us), few people ever see it. Every year, we produce more than we can sell because we keep assuming that word of this treasure will finally get out in public. Since it has a slightly pendant habit, Allium kiiense is best located where you can see it close up, and ideally from slightly below.
