I've never seen it for sale or anyone posting a pic of it ~but there is one in my book on Echeveria cultivars which seems a match. I first thought yours looked like E. minima (but you didn't give its size, which may have made me lean that way). Echeveria 'Ben Badis' looks like your plant, with parents E. purpusorum x E. derenbergii. You have a very nice looking plant there! =)

I wish I had flowers....but, alas, I wonder if the marginal zone will preclude flowers? I did a google search with 'prolifica' as the species, and didn't see anything with leaves this narrow. I wonder if this could be a hybrid? Josh

I was looking at the pics you posted now, and didn't see semp...now I see Aeonium, that was not easily recognized in op. Those plants are summer dormant, and shouldn't be in strong sun and lots of water. But summer is coming to end, and they should start looking much better. Maybe you should sort out plants you have right now, learn about each of them before buying more - none of my business, just a friendly comment. It isn't so crucial to know the name of exact sp, cv or hybrid, as long as you know what is the genera to begin with. Sometimes, it is more difficult to maintain plants in community dish, since they could have some different needs - as is the case with aeoniums. Most succulents needs are the 'same': good drainage (potting mix and the container with drainage hole); lots of light-sunlight; good air circulation. But there are some that grow better in less sunlight, and others that prefer lots of it. Some are more 'sensitive' to being watered during dormancy, while many are much more opportunistic and will continue growing well regardless of it, it given regular watering, sunlight and warmth. Location should also be taken into consideration. For example: while in my zone semps grow great in full sunlight, they are bit more sensitive to it in z10 because of sunlight being generally much more intense and heat is higher. Looking at the photos, I do not think your soil drains well enough. How often do you water your plants? In temps you have, potting mix should be drying fast enough, unless it is water-retaining. What is in your potting mix? I never had E. 'Blue Prince", just commented on what I see in pics. As I said, it may have been put into too much sunlight suddenly, not that it doesn't need it. I keep all of mine in full sun, but they get acclimatized in spring. What were the roots like when you got it? It may not be able to absorb water properly if they were dead (they could have dried up) - I am just guessing. What is the trailing-sprawling plant behind it? It looks bit etiolated in the photo. That means less light than it needs...

Haworthias don't mind the heat at all. They don't really go dormant but will grow in response to rainfall and light patterns. What you want to do is keep the roots cool. Continue watering at least weekly but put them either under shade cloth or somewhere where they only get 1-2 hours of direct sun a day, preferably morning sun when the temperatures are cooler and make sure the pots aren't being exposed to the sun: put them close together, maybe put a ring of rocks around your pots so that the plants on the outside of the table or whatever surface you are growing them on aren't more exposed than the ones towards the inside
