I dropped some Indian Blanket seeds at my parents' cemetery plot and at a park on Monterrey & Houston. Hopefully they'll sprout next spring. In the summer I want to add Bluebonnet seeds to both those locations and maybe a third one.
I harvested some Blanket seeds from flowers outside the cemetery some years ago. Now I have them in my backyard. To help the flowers re-seed themselves, I just water occasionally and mulch garden waste with the lawn mower to add an extra layer to the turf.
