OPP Posted March 15, 2013 Finally got around to sowing these cactus seeds. They came up very quickly and the biggest was 1cm tall in a week. From memory 10 seeds were sown and 4 came up. To my suprise the second biggest one disappeared last week. all that was left was the body but it was cut off at the top of the sand. I'm guessing a slug ate it!?!? Hoping to see these become adults and take on their true shape } 3 Share this post Link to post Share on other sites
Optimystic Posted March 15, 2013 (edited) I've been talking to a cactus dealer about a spiralis! I just told her yesterday I was thinking about seeds but didn't know if they would come true to seed so i'll be keeping up! Theres one for sale on ebay out of Argentina but its a take your own risk auction and Im just not gonna do that...Very cool! Good luck with that Edited March 15, 2013 by Spine Collector Share this post Link to post Share on other sites
Evil Genius Posted March 15, 2013 Hi OPP, dont think that they will turn out spiraling as well but maybe you are lucky. Sand is not really optimal for cactus seedlings so you gotta becareful that they dont shrivel up because of not enough water. Keep a very close eye on them. I stopped sowing them directly in sand as the quartzy crystals kinda work like a magnifying lens. Besides, the particles are so small that it is easily overgrown by moss and shit. Maybe try covering the top layer with some quartz stones. bye Eg 1 Share this post Link to post Share on other sites
OPP Posted March 15, 2013 EG-Usually my seeds go in a store bought cacti and succulent mix with a tiny layer on top to cover the seeds. Must have run out of cactus mix because these are in 100% sand. Will transplant soon. Why do you think that they wont spiral? I have read that they dont start twisting until 10cm tall. Share this post Link to post Share on other sites
Evil Genius Posted March 16, 2013 (edited) Hi OPP, as far as i know Cereus Forbesii Spiralis is a cultivar and not a distinct species. As with most cultivars, they oftenly dont pass on their, lets call it a genetic defect, down to the next generation. It can happen but i actually never saw one seedgrown Cereus Forbesii Spiralis. All i´ve seen were cuttings from the known Cultivar. But maybe your lucky and the spiraling gene in the spiralis is so dominating that it shows in the seedlings, who knows. I keep my fingers crossed for you. bye Eg Edited March 16, 2013 by Evil Genius Share this post Link to post Share on other sites
zelly Posted March 16, 2013 I picked one up a few years back, major disappointment in that offsets from it grow naturally. Share this post Link to post Share on other sites
Optimystic Posted March 23, 2013 (edited) According to this link they do come true from seed and they are often crossed with Cereus Peruvianus for different traitsalso theres a nice pic of what is said to be the original plant in Brazil... I would guess different crosses might do different things...A coupld of those photos are supposed to be of seedlings... I'd love to see an update of yours down the road OPP http://www.cactus-art.biz/schede/CEREUS/Cereus_forbesii/Cereus_forbesii_spiralis/Cereus_forbesii_v_spiraliforme.htm ... I gave in and bought me a Hildmannianus Tortuous "Corkscrew Cactus"...should be here by the end of this coming week... The spirals are not quite as tight but they're said to be more cold hardy than the Forbesii... I've got another that I think is a Hildmannianus Monster though sold to me labeled "Cereus Peruvianus Monstrosus" and it was said to have grown where it gets snowed on a few days each year Edited March 23, 2013 by Spine Collector Share this post Link to post Share on other sites
False Peyote Posted January 19, 2023 Any more on this? How can we make a spiralling trich?! Share this post Link to post Share on other sites
