Some mystery plants in one of my flower patches finally bloomed and I found out what they were. I thought they might be a bushy form of Morning Glory, but a check online revealed them to be Four O'Clocks. The flowers are very pretty, but the wait was long. I never planted them before and if I do again, at least I will now know it will take a few months before they bloom.
The succession of blooming is something gardeners have to learn, from the Spring ephemerals through early Summer perennnials and then a lot of members of the Composite family, including Sunflowers and Black-Eyed Susans bringing up the rear in late Summer and Fall. Now I know where to expect these ones.
