Hi Mike/@blondmyk.
I fell in love with a Desert Rose for the first time when I saw the blooms on one at your South Texas Botanical Gardens. It wasn't labeled and I had to ask around to find out what it was. Since then, I have enjoyed our visits to Corpus and visiting the nurseries there. It has been a love affair with adenium ever since. 5 that I have are in pots like yours. They were gifts from an ATP member and are thriving on my sunny outside window sill. two others are also doing well in Bonsai pots. But listen to the Experts here, They will steer you well with their knowledge and experience.
