    The Key Tree Cactus at Cactus Island

    This is the cactus that started it all for me: the Florida Key tree cactus, Pilosocereus robinii.  It is our largest – a green, branching columnar cactus that can reach 33 feet in height with many arms, and what a few of us here call “Florida’s own saguaro”.  Occurring only in the Florida Keys inside the U.S, it also is found in a few spots in Cuba and their coastal keys, reportedly also on a few islands of the northern Bahamas as well. Stems can get 4”+ thick and thicker at support base. Flowers are nocturnal for one night only and have somewhat of a garlic odor. Unlike many others…

    Spring Cactus Flowers Everywhere

    I don’t think I’ve ever had so many flowers at the cactus farm at one time, and some uncommon ones at that. The really wooly blue Pilosocereus with curly white wool on every areole is some kind of hybrid from California, and I’m guessing someone crossed Brazilian P. pachycladus with Mexican P. leucocephalus or P. leucocephalus palmeri. The single muted mauve flower on the turquoise P. albisummus (CS140 Sitio Grande) was an early surprise for 4.7 year old plants. Twin flower bells with green hypanthium on what is likely Xiquexique gounelei ssp zehntneri are a knockout, while the 20-some buds on the patio gem Harrisia aboriginum candelabro stunned us, especially…

    A Forest of Native Florida Cactus

    I took the greenhouse tent canopy off early this Spring, expecting to get some growth with the stronger light, but this blew my mind. To all I met at recent Florida plant shows, here is the video of the tall “bamboo” forest of aboriginal prickly apple cactus I promised – and thank you for your purchases! These things are pupping, budding and fruiting like crazy and it’s early in the season. I’m saving seeds from flowers I hand-pollinated on nights when Harrisia fragrans weren’t in bloom, and I’m armed with professional pollination bags just in case of a megabloom. H. fragrans self-pollinates with even a light breeze and I suspect…

    Cactus Flowers Open at Night

    This past week four have opened so far, and many more are budding on the aboriginal prickly apples. The mahogany and rose colors on the hypanthium and sepals distinguish this species’ flowers. I’ll be mesh bagging others now that both species are in bloom at the same time, to avoid possible hybridizations. Here are the largest of both species of prickly apple and the mama Royen’s in their new “cactus cairn” raised stone beds. I’ll add onto the sides of this large round one a couple of smaller satellite beds with Consolea moniliformis, to make it a habitat garden.

    Some Cereus Spring Flowering

    One year later, the other Florida Harrisia species I’m growing has finally come into bloom! The aboriginal prickly apple cactus, Harrisia aboriginum, is sporting flower morphology true to description and with luck will produce bright yellow fruit. Because of habitat destruction, this endemic cactus is critically endangered and almost went extinct in it’s Southwest Florida coastal hammock range. The dedicated species tent, now called the Aboriginarium, will have to be built up higher as these are reaching 7-9ft tall and potentially twenty feet. It is quickly gaining popularity with Florida gardeners who can grow it in their yard sanctuaries. Last year’s Harrisia fragrans yielded a lot of the bright red…

    New Greenhouses, Last Blooms and Fruit Before Winter

    The downside of mega propagation of cactus is where to put them all come Winter. The last couple months of Fall bring worry over preparedness, then ideas and effort prevail. I am getting closer after setting up and securing cactus greenhouses #5-8. Now comes the heavy work of building doorjambs and insulated doors on all of them. Heating the greenhouses to keep temps at or above 43f over the nights until March will not be fun or cheap. I’m already moving our army of spiky green things into the shelters as the weather changes. The Outsunny plastic and metal greenhouse kits, when modified with improvements, have worked great. The warm…

    Evening Magic in Photos and a Video

    This mantis has been eating well, because everything in there looks healthy enough to put on such a show in the absence of destructive bugs, though tonight the place was abuzz with pollinators. That horsefly in the video at 0.38 was following me as I walked through making it. I’m looking at a dozen flowers that will likely all fruit, with more opening this week. These are open one night only and close up at sunrise.

    From Bud to Fruit in 46 Days

    No, this is not some unusual variety of dwarf watermelon we’re growing at Cactus Island. That little black cactus bud I shared on June 8th? It flowered, fruited and grew into by far the largest fruit I’ve ever seen on any species of Pilosocereus. This eight foot plus Brazilian P. azureus took about 12 years to flower from germination and I’ve had it since 2012 when I bought it as an 8-10 inch potted pair. This biggie has to be an anomaly, because the seed count after cleaning was 5374 – way more than the normal, roughly 1800 I’ve been seeing in this genus. Maybe, just maybe, the two winters…

    Mega Bloom Video, Fragrant Prickly Apple

    Tonight the flowers and bugs are out in Tent #2, so I made and spliced together three video clips of six Harrisia fragrans buds swelling to open, expanding and finally, nearly open. That side of the tent provided a bit of a miracle and the right conditions because three quarters of the stems are now in some stage of flowering. We’re looking forward to seeing lots of bright red fruit to make it look like Christmas in July in there.
