Gardeners' Notes:

This is the bloomingest plant I have ever seen. And it does it all with very little water and lots of heat.

It shatters its seed pod thus reseeding itself in a limited distance from itself. Personally I deadhead them every 4-5 days and toss the seedheads where I want more plants to grow.
