Parsley worms (aka. black swallowtail butterfly caterpillars) grow quickly, and the one living in my parsley plant is no exception. This caterpillar is packing on the grams at an impressive pace.You saw the photo I posted a few days ago.arsley seeds are very easy to start and I have a parsley plant that is now 2 years old.
