Seed ripenslate July

Eurasian allium species growing in a pocket of our rock garden. It entered our garden as seed of 'Allium platycaule', but when it clearly was not that, I got some online help to identify it (there's also a possibility it is A. hymenorrhizum, which is distinguished by its strongly falcate [curved like a siccle] initial leaf emergence). The little pink flower clusters are nice enough, and I like how they are held on tall slender stems. The seedheads, developing throughout June and July, keep the attraction going after the flowers fade. They stay very tight, which I find more attractive than the looser seed clusters of many of their genus-mates.

Buds just barely opening, with the papery husk that covered the entire cluster still hanging on

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

Seed for this plant is included on my seed trade list
