We grow a ton of dill and parsley — not that we’re great cooks but they are the larval food for black swallowtail. (We get a little bit, just not as much as we plant.)
They’re cool-season plants in Florida so I’ll be out with dill and parsley seeds in late February. They’re easy to plant, just rake aside enough space for them to actually hit the ground and then water in well. There are at least a couple dozen seeds in each pack so there should be plenty for both you and the caterpillars.
Usually when you read about dill and parsley being attacked by giant caterpillars, the posts are written by people who don’t understand that certain types of butterflies will only lay their eggs on very specific plants. Black swallowtails need parsley and dill, so the easy (and nice) thing to do is plant extra.
They will destroy the plant. In a long growing season, the plant will come back but the short cool seasons in Florida usually mean I’ve lost the chance to eat them. But that’s why we plant waaay more than we could ever eat …
Please two packages of seeds (total) per order. It’s time-consuming to collect, package and mail them, even though we really want more people growing food for themselves, caterpillars and butterflies (or write firstname.lastname@example.org) and tell us why you need more.
