All the connector roads between 30A and 98 used to have liatris in abundance. I know 395 best, and the variety there was a VERY tall cultivar, and it was beautiful for weeks late in summer or fall each year.
I remember being horrified, way back in the early 90s I think, to see a woman with a van full of buckets she was loading with cut liatris. Like enough to do the flowers for a royal wedding or something. I was not confident in myself at the time and didn't say anything, didn't know what to say. Might be different today, but the liatris are long gone thanks to her and others doing the same thing.
Some states actually have laws prohibiting the harvesting of wildflowers, which are regarded as part of the public commons, owned by all and therefore harvestable by none. Ladybird Johnson got that whole thing started, as I recall.
Anybody know if we have such laws here? And if we do, does anyone really think the Sheriff would enforce them?
