Toni-Marie The grafting stock is Harrisia jusbertii. I have experienced a successful result of luethyi tubercle grafting. A jusbertii is also used as the grafting stock for the tubercle grafting. Frank Here is a link that might be useful: luethyi / tubercle grafting

I also thought it was too big for the root stock, but then I remembered that Trichocereus photoshopensis comes from the magical land of E. Bay. The spination of the Tricho on a stick does look like my terschekii. What a marvelous, wonderful popsicle. I prefer the ones with the spines removed, but serving them with spines intact is the way they eat them in Utoobia. Nice bunch of monsters you have created, Dr. Uphony Frankenstein!

An old post was resurrected! I have been swamped with life (work, kids, etc.) this year, that's why I haven't been contributing much of late. My apologies. I have also been involved with another somewhat related hobby: developing a reef aquarium. Let me tell you, many coral and other reef animals absolutely rival succulents for color and form. Yes, I do have a greenhouse, which serves 2 purposes: it protects plants from too much rain - especially my Mesembs during the summer and cactus during the cool time. I keep as many plants as I can outdoors unprotected during the spring-summer-fall. I overwinter pretty everything except the true tropical plants (Adenium, some Pachy) in my unheated garage. Soil mix of choice for mesembs and other smaller & slower species is a formula with various proportions of turface, garden coil, fine gravel and pumice. Everything else is in a mix basically of 50-50 turface to perlite. Fertilizer is diluted liquid algoflash for most plants. Bigger things just get a healthy dose of Osmocote slow release + micros in the spring plus added Mag + gypsum. x

Garrett, Looking up Haworthia marginata var mariatii showed two different pictures on Google. One with white tubercles (one side only) and the other like the book describes smooth both sides and whitish skin, while pumila has white tubercles on both sides. Both are in different groupings in Pilbeam's Book on Haworthias. Pilbeam discussed the big trouble ID'ing with so much interbreeding in the hobby. With each other plus with Aloes and Gasteria. You see the almost same plants with just the least little difference and then someone puts in in a new class. I currently have about a dozen Hawothias that need ID'ing. Waiting for them to get some size and age to tell them apart. I am pretty sure now with Conny's help that this is the correct ID but will keep it open for discussion. Conny, I purchased my limifolia variegata from 'Out of Africa'. Cost & trouble of shipping overseas is always a problem. If not, I would try to get you one. We trade a lot here in the States.
