The Tiger Swallowtails love that FL paintbrush. I did buy some native Rubeckia a few years ago, so far it keeps re-seeding in the same general area....love the bright yellow flowers. I have Indian blanket all around the garden, I have moved some out of the lawn into the flower beds with a 70% success rate. Last year I cut off the dried seed heads and spread them around on the sandy east side of our house where nothing grows and have a nice new patch of them this year. I'm glad my neighbor loves them and letting them grow on her side too.
