First Flower on the Key Tree Cacti








There is a first flower on Pilosocereus robinii – Key tree cactus (Lower Matecumbe Key). It is a magical week at Cactus Island. Many more areole swellings are forming on this one of the two six-year-old giants. The Big Pine Key plants (bottom-right photo) from the second of two genetic groups are making me think now that those too will be producing buds in two or three years, at this rate of growth. Outcrossing between the two main gene pools is the best practice for propagating this species by seed. The frame on this garden is ready for plastic and propane heat in preparation for the coming winter.
