This is probably Hooker’s onion, Allium hookeri, a species which is known to be cultivated in home gardens in the eastern Himalayas andother countries in South East Asia (confirmed by Allium expert Reinhard Fritsch at Gatersleben). This plant was found on a market in Aizawl, Mizoram, Eastern India by Paul Barney. Paul sells this form under the name Allium hookeri “Zorami”. It gets a mention in my book, although the cultivar name isn’t mentioned! It is growing slowly in my garden. The pictures are taken during a visit to Paul’s nursery Edulis near to Pangbourne in the Thames Valley, UK.

I have now been growing 4 types of Allium hookeri for a while.
A. hookeri ssp. muliense, A. hookeri ACE 2430, A. hookeri ex Chen Yi & A. hookeri ‘Zorami’.
Now having had experience of all these I am increasingly impressed with ‘Zorami’ due to its ability to repeat flower from June to November, earliness into leaf, favour, and attraction to honey bees & solitary bees.
Where can I buy Allium hookeri ‘Zorami’ ? Please help
I only know that Paul Barney at Edulis Nursery in the UK has sold it (he collected it originally! He commented above with his contact details.
