All three of my Caesalpinia pulcherrima shrubs in the courtyard are now producing flowers. I took this close-up of one of the flowers this afternoon.
The individual flowers only last a day or two, but the racemes have dozens of flower pods opening from bottom to top which gives the appearance of having perpetual orange, red and yellow flowers in the courtyard. We have the colors all summer and into the fall.
