Allium nigrum reviews
Reviewed 31st August 2019 by Rebecca Perfect for providing height in the borders and interest for bees |
Reviewed 5th July 2019 by Hello Pamela Lovely strong long lasting flower heads but was expecting white flowers not purple! Not sure I was sent to right bulb. |
Reviewed 5th July 2019 by Hello Julia I ordered 15 Allium Nigrum bulbs, (which are specifically white,) in Spring they came up as eight purple alliums. I did get a refund, however, so the after sales is good. |
Reviewed 26th June 2019 by Jennifer I haven’t had much success with this before, still flowering |
Reviewed 26th June 2019 by Jennifer The wrong allium was sent. Bulbs ordered for a white border but purple received. Very disappointing, a year lost and will have to start again |
