Where to buy ammi seeds
Varieties we recommend, and where to get them:
- 'Green Mist' ammi (Ammi visnaga) (best for denser, greener filler): Johnny's Selected Seeds describes this related Ammi species as a sturdy bouquet filler that complements any color scheme, with denser, greener flower heads than the flatter white lace of Ammi majus above.
