Cactus grandiflorus (Selenicereus grandiflorus) potted plant, organic
$11.00 – $30.50
Family: Cactus (Cactaceaea)
Zones 10 to 12, otherwise grown as a potted plant indoors or greenhoused, protect from frost.
Note: There are many examples of Selenicereus pteranthus (princess of the night) being sold as “Cactus grandiflorus.” They are actually different plants. We obtained seed of verified Cactus grandiflorus (Selenicereus grandiflorus) for this offering of potted plants. They are exactly as per photo, seed grown, not from cuttings.
Native to the Caribbean. A rare epiphytic cactus. These can be grown outdoors on the gulf coast and will benefit by being trained up a tree–they will grasp the bark with aerial roots. They also make fast-growing house plants, requiring minimal sun, soil, and water. The spines are almost benign–I’ve handled them extensively and never been injured. Flowers are more likely to appear on specimens grown in the greenhouse. The flowers are very huge and white, intoxicatingly fragrant. They usually express for one night only, during the full moon. Traditional usage: Eclectic. Heart tonic. Cultivation directions: Pot up to a gallon of cactus mix on receipt. Place in the greenhouse, or indoors in a light window. These will droop or climb, depending on the availability of a trellis (or the curtains!) Water once every 3 days during the summer, once every 3 weeks during the winter. Water more if the plant is getting lots of light and heat. Water less if the plant is getting only filtered light and room temperature. Growth of 3 or 4 feet in a season is not unusual. Space plants 2 feet apart.

Hello Richo, do you have any repotting advice for these gals? I have three of these I got from you that have been left in much too small of pots for many years and need repotting and tending. Though the above ground growth is fairly large, they are not super healthy. My inclination is to cut them wayyy back, and then pot them up in new pots and dirt, do you happen to know if they respond ok to this kind of aggressive trimming or have any advice on how to treat them? Thanks!!

Hi Alex, Thanks for staying in touch. One good approach is to fill some 6-inch pots with cactus mix and train the runners over the surface. Once they root in you can clip them free, and these will grow rather nicely–fresh. If the crown is funky you can discard it. Otherwise its the standard repot for succulents and cacti–depot, remove all necrotic tissue, trim the roots and repot to new mix. There is a great monograph on these in “Growing Plant Medicine Vol 1” and info on how to use the plant in “Making Plant Medicine.” Richo

hi desi, thanks for staying in touch. I personally mix my own. The complete recipe is in “Growing Plant Medicine” Vol 1 but in short its 50% fast draining and 50% compost. There are some really questionable products out there if you’re trying to buy by the bag, but I like “black gold cactus mix” and you can google that. I checked the ingredients, looks pretty good. richo
