    Tall, Mature and Uncommon Cacti for the Luxury Estate

    Cactus Island Nursery is about the only place in Florida where you can find very large and uncommon columnar cactus for sale. I grow nearly every one of them from seed and it takes many years to get these gorgeous, spiky plants to 3ft, 4ft and even 6ft tall. If you’re looking to design and build the dream xeric oasis within your indoor or outdoor garden sanctuary but don’t want to wait forever for plants to slowly grow to museum exhibit size, Cactus Island has what you need. Most of what I offer for sale will only grow outdoors without protection in coastal Tampa and South Florida, and in North…

    Native Florida Cactus and the Caribbean & Florida Stone Cactus Garden: 2024 Highlights

    Everything I’ve grown and built at Cactus Island Nursery has exceeded what I’d hoped for after over five years of work and a big move to North Central Florida. My mother and I have built and maintain a productive homestead on top of that. The first two Key tree cactus – Pilosocereus robinii – are over three feet tall and the Big Pine Key planting of the species has put on some real growth since March. It is the state’s largest cactus by far, referred to by some as Florida’s own “saguaro”. The 25 or so “batch champs” I have set aside and will I’ll keep for seed production while…

    Pilosocereus aff. flexibilispinus Flowers and Fruit

    The huge spiny cannons from Sitio Grande, Bahia in Brazil finally produced flowers on more than one stem, and close enough together in time that I was able to gather and freeze the pollen from one plant and tap it on another flower, yielding my first fruit. Tonight I did another and might have a seed factory going shortly. I germinated these in August 2018 and have enjoyed their rapid growth to dizzying heights. Someone collected seed of this species in 2009 and listed it as CS140 but it was misidentified by that collector as another in the genus. Luckily, a famous cactus botanist/explorer pointed it out as wrong and…

    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. aff. flexibilispinus (CS140 Sitio Grande, Bahia, Brazil) 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…

    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…
