Tho' Crown of Thorns (Euphorbia milii) is a succulent, they like a lot of water, more than you think they would. I grow a number of these, I give them the best light I have (west windows), ample water (til it flows out the bottom, I do mine once a week) & fertilizer May thru Oct. (several of mine bloom a couple of times a year, once stays in bloom almost all year). It's characteristic of them to have most of their leaves up top, but yours should also have some along the stems. As you step up light & water, it should get leavier. The unknown plant is a Haworthia (can't say which), it's sort of closed up I'm guessing due to lack of water, water it more, it should green up a bit (rather than the gray/green it is now). The new plants are another Haworthia, a common one, fasciata or attentuata maybe, check some picture sites for IDs. Haworthias do not want strong light, they pefer medium light, I'd say yours are fine w/ that. I grow my Haworthias on the outer edges of my windowsills, they don't need the strongest light & some actually prefer it on the shadier side. The last plant is a cactus (I don't grow any so can't say which), that fake straw flower on top should be removed, it's glued on, not sure how to take it off. I didn't look at the Jades. The Tiger Aloe grows like that, there's nothing wrong w/ it, but yes, could use more light. I might even re-pot that a bit smaller. That Aloe that's spreading out from the center, needs something, if it were mine I'd cut them all off an inch below the leaves & pot them in DRY soil to re-root them. They're not going to recover from that, their lower stems aren't going to leaf out again, might as well re-root them. All your plants look far too dry, also the mix looks too hard. What are you using for dirt? I'd start over w/ fresh cactus & succulent mix, w/ abt 30-40% perlite added for fast drainage. This way when you water, they'll be able to drink & then it'll drain fast. I suspect your mix is so hard that they're not able to drink much no matter how much you water, tho' suspect you're watering too little. You might try reading around on the Web to learn the care for these plants individually. In my opinion, if you only have east windows, focus on Haworthias & Gasterias, I'd forget abt the Aloes altogether, you simply don't have enough light, it'll always be a struggle for them.

Amy, If you want to achieve all possible colouration for a plant, with most succulent plants you will eventually acclimate to full sun. That's not to say they won't grow well or look good in less sun, it's just that they're happiest in full. That mumble-jumble being said, the list given below is something you might use for lower-light plants: Kalanchoe Aloe Gasteria Haworthia Cotyledon Tropical cacti (Selenicereus, e.g.) Aeonium Sedums Echeverias, Pachyphytums, Graptopetalums and their crosses I would shy away from Dudleyas and other winter-growers for the simple reason of having to control their water intake in the summer when (almost) everything else wants water. Of course, this is just a partial list - you might inquire as to a C&S club in your area from whom you can get on-the-spot guidance and counseling - that is the best information for you in your area.

This development on this variegated H. attenuata is a bit disappointing. It was a beautiful plan when it arrived, but now not so much.. Sadly I think it was infested with mealies at the nursery in Germany and they took a long trip here and kept attacking the poor thing, so slowly it was drying up and falling apart, and that's when I found the problem. I emailed the seller and they said to treat it with my spray (50% rubbing alcohol) and even brush it every other day, and that later it will grow new heads from the sides. I hope he's right! At the moment, because of all the spraying and the stress, some leaves are turning quite red (the picture lightens it).

They are so much brighter than CFLs. Unless you have lots and lots of CFLs. Homegrown hydroponics carries them for around $55 now I think. So maybe you could try just one or two 4' T5HO and see how you like it. Frame/suspending the fixture can be done DIY style and with low cost. Two lights would be provide good coverage for a 150cm x 40cm space of Haworthia, Gasteria, smaller crassula, and the like. The very edges may be a little dark but probably you have smaller cuttings/propagations to put there.
