Those are new to me and they are adorable!

I did years ago - not on purpose, tho. They were in a mix of flower seeds and did fairly well in the ground. They did not reseed, tho.

I found a blog from a Florida person who said they did. It does not like the heat so they are gone by May/June. For a buck something why not see what happens.

I was picking up cosmos seeds and saw these, bought them without looking them up!

Put them around the silver maple tree to help keep them cooler, hopefully enough sun light to grow.
