hi yes i believe its a type of echeveria not a sedum it has velvety leaves that are tinged red

Yes, #2 and #3 are Mammillarias, I'm not positive which. #4 is Echinocactus grusonii, very much a baby still. #5, Pachypodium? Someone will know this for sure. #6 is a Stenocactus, very hard to tell the different species apart. #7 is Frithia pulchra. #8 is Mammillaria carmenae.

Oh my. That wasn't even in my initial research. It was frustrating since at times all i could see online were the flowers. That was a great clue. The growth pattern/ habit was confusing me, it didn't look like any of the previous genera i mentioned. It does look similar to that of corpuscularia. I was leaning towards delosperma and when i researched the names you gave me, i found out they were from the same subfamily and tribe, if not interchangeable or synonyms of each other. Difference i could see was that delosperma are papillate and mine has very smooth almost satiny leaves, a feature of corpuscularia. However, most of the Corpuscularia or Delosperma lehmannii in google images really had plump/ chubby and compact leaves. There were a few long-leaved ones but then they have reddish stalks and mine doesn't (though that could just be due to different growing conditions). The longest leaves on my plant are 1.5 inches or 4cm and the stalks have papery sheaths. Thank you so much for that info rosemarie. I guess i'll treat it as a corpuscularia for the time being.

I think it needs a good soaking. It is trying to conserve moisture and is dropping old leaves. If you are unsure, stick a long toothpick or wooden kebab skewer deep into the soil and leave it overnight. Pull it out tomorrow, and if it doesn't feel dampish, you should water. It is possible your soil is compacted into a hard mass which water cannot soak into. When you water, watch if the water comes out the drainage holes immediately or if it actually soaks into the soil. If it pours out immediately, immerse the whole pot in a deep tray of water and let it soak for a few hours. Then use the wooden skewer to determine when it needs to be watered again. The purple colour is likely from the high light levels. happy growing! Breton
