Zinnias and verbena are popular nectar sources for butterflies! I saw you had them on your plant list, you should be seeing more butterflies, the black one you saw was most likely a black eastern swallowtail, if you plant dill, parsley, or rue,( they are herbs), but also host plants for the swallowtails
@purplebird @treefrog44 In that case, I just saw a female. It was larger. So funny @treefrog44 , my son asked to buy dill last night. Lol. I told him no, bc we aren't making pickles this year but maybe I should reconsider!
You should! The caterpillars are so neat to watch, they go through 5 different phases... it's about a month and a half from egg to caterpillar to chrysalis to butterfly...I have pictures of some I had this spring in my garden on my garden board if you would like to check it out! :)
