OK, I admit it, some of my first crotons were Petra. Today I noticed my yellow Petra has male flowers. Can't recall ever seeing any of mine or anybody else's Petra flowering.
The Petra's flower often in my garden. I have a few older plants from the colorful Petra. The Yellow Petra has flowered male flowers since late summer. I used the pollen on my Diane female flowers and it looks like it worked. Now I see the female flowers forming on the Yellow Petra.
