I'm in zone 9, and so far in 2018 my potted plant has grown from 12 inches to 4 feet and is flowering. I cut it back to 12" in Dec. so it's easy to bring in my garage during winter freezes. I also put the cuttings in water to start a few new plants just in case I lose my plant. Last year the plant got 6 feet tall by fall. It would have gotten taller, but I trimmed it every couple of months, so it got bushier. It's a such an eye-catching color.

I have these plants blooming this week, June 15, 2018. They are 6' and growing near my red ones by a wood fence where my neighbors can also enjoy their tropical look from their pool just over the fence. They'll bloom most of summer and grow to about 7 feet tall here in south Louisiana, zone 9.

Sorrell is a popular drink in the Carribbean during the Christmas season. Touching the outer layer of the pods and then touching your skin will cause severe itching.

This summer was the first year after at least 10 years that I actually had new plants volunteer from seed. I had tried on several occasions to plant seed and none ever geminated. This year I kept finding new small plants popping up all in the lawn. This year my neighbor discovered a plant growing probably 100 feet from any of the others I had given her. It is amazing how fast these plants can grow.
