Uncommon Columnar Cacti growing in the Nursery
Pilosocereus is a medium sized tree cactus genus that occurs in Cuba, Florida Keys, Puerto Rico, Jamaica, Bahamas, Mexico and South America. It has a particularly strong and unusually diverse presence in the semi-arid scrub lands of Brazil. Some in the genus can reach 30ft tall and 4-5 inches thick, and many species sport a flower bearing wooly cephalium or pseudocephalium near the tips, depending on the species. I am growing a number of Pilosocereus species that are rare in cultivation and I plan to sell most of these when they are a bit larger, but I’ll keep a few from each species for my own seed production. Where I can, I’ll add specimens from different provenanced field collection numbers to avoid perpetuating the same clone before I hand-pollinate flowers for seed.
A third genus of medium-large tree cactus found in the Caribbean is Stenocereus: Stenocereus Griseus (one in photo above) is common in the ABC Islands and referred to there as Kadushi, and the similar but more densely needled powdery blue-green Stenocereus Hystrix is found in Cuba and Jamaica. I’d like to get my hands on a couple of these rare gems but the few times I’ve seen them for sale they were prohibitively expensive, so it’s looking like I’ll be starting them from seed for now. Our S. Griseus should eventually yield tasty cactus fruit and seed.
Finally, I had to add a picture of the “cactus blueberry” Myrtillocactus Geometrizans. The mid-winter fruit, called bilberry, looks and tastes like blueberry. Commonly used as grafting stock for those red, orange and yellow ball cacti at your local box store, they can reach 9ft x 15ft shrub size if allowed to grow naturally in ideal conditions. Our bilberry cacti are about to get divided today and planted in amended ground beds that were started by the previous owner (and finished by me two days ago) up near the wild blueberry patch. It’s worth the time to surf the web and see mature specimen pictures of all of these beauties.

You do have a green thumb! Wow!

Thanks! When I was in my early 20’s I would hear the phrase “green thumb” and wonder why that attribute skipped me. Art and botany turned it around, starting with the lace plants. It’s addictive stuff.
