Visnaga, False Queen Anne's Lace, Toothpick Weed 'Green Mist'

Zone 8b coastal SC - I purchased Ammi visnaga 'Green Mist' and Ammi visnaga 'Queen of Africa'. The flower on both plants looks like Queen...Read More Anne's Lace. The 'Green Mist' foliage looks like dill and 'Queen of Africa' looks more like flat leaf parsley. I was looking for a plant that would be used by Black Swallowtails as a host plant. Since this is in the same family as parsley, dill, etc it was a good choice and had Black Swallowtail caterpillars on it.
I purchased 6 of each variety for a community garden. They both reseeded and this year there are lots of plants. We have had a mild winter and some plants are about 10" tall. This plant is not a commonly found in the nurseries here but the it is obviously easy to grow from seed. Hopefully the reseeding will be controllable.
