| I was actually stuck growing all of my succulents indoors this summer. I am planning on doing a writeup about the current results. The big thing is whether or not they manage to survive this winter. I also wouldn't really call any of these shade *loving*. That being said, there are apparently a number of shade-loving Amaryllids that are rather succulent, and might work. Clivias are neat and apparently can take a lot of shade. Haemanthus albiflos, from what I gather, is jungle understory plant, although from my understanding there are some fairly similar looking Haemanthus which are full-sun, desert plants, so check labels. Ledebouria socialis is in the hyacinth? subfamily? and also pretty easy. Some general observations: - Haworthias attenuata/fasciata (are these the same thing?) grow more or less fine on a windowsill and will even flower. A lot. Which would be great except their flower spikes are boring and huge and mostly just get tangled in other things. NOT sure how the more fenestrated ones like cooperi or retusa would do, though. I tend to think they'd want more light. - Jungle cacti like Zygocactus or Rhipsalis aren't too problematic. Desert cacti are pretty much a lost cause and I wouldn't even bother. I have had luck with Leuchtenbergias, so far, though I'm not sure how that'll last. Oh, so far I've had essentially zero success with globural/barrel-shaped cacti, if that's worth anything. Pereskias and Pereskiopsises will probably do fine but those are leafy and barely succulent, so... - In terms of Euphorbias, I have an E. Lactae, E. greenwayi, and an E. antiquorum 'tortilis' (something like that) growing on a north-facing windowsill. Growth has been pretty robust, consistent, and not etiolated or weird or anything. I've also seen E. Trigonas doing pretty well indoors for long periods of time. In general the Euphorbias, compared to the cacti, have not been problematic for me. I'd avoid the medusoid kinds, though. My E. Flanagani and E. Globosa are basically vines, now, although they actually did that outside, too, so I don't know what they want. I'm also not having as much luck with my E. anoplia. It looks like it's etiolating somewhat but I'm not sure to what extent at this point. - Leafy things will probably do better because leave collect light or something. I think I read that, somewhere. - The two Alluaudias I have seem to be doing alright, although growth has been inconsistent. That was true when i had them outside, though. The Montagnacii hasn't done anything since I bought it, and my three-branched Procera only has one branch that ever puts out growth. - Echeverias I have a really hard time with. They tend to etiolate REALLY badly for me indoors. Some fall apart. Some actually start growing normally after awhile. Some just attract mealies and make life miserable for everyone. I'd tend to group those with desert cacti in the "don't even bother" group. - I've seen Pacyhpodiums (geayi and lamerei I think) growing fairly robustly indoors, although these were in like lobbies that had huge, glass windows. Might be worth a try if you can get one for reasonably cheap? - Mesembs as a whole are another really questionable group that I haven't done much with because lithops are notoriously rot prone. I'm sort of having success with my Trichodiadem bulbosum, but I'm not sure about the Faucaria. Both looked bad in the winter -- the former defoliated, the latter deflated. Both revitalized quite suddenly this spring, but I'm NOT thinking that the Faucaria is growing normally, although the extent of this and its future impact isn't really clear. - Avonia quinaria's actually proven surprisingly easy so far. That was surprising. |
