The four o'clocks that I planted in tubers are growing great. So are other four o'clocks in various colors all around the garden that self seeded from last year. Some of those I moved around to were I want them to be instead of were they were popping themselves up.
But those seeds I tried to start did not come up. Not a single one! I was so busy I didn't have time to try again so I guess I will just have whatever is growing here now.
