I picked up a Fenestraria aurantiaca at Home Depot late this winter. I've seen these many times before, but for some reason, it looks like a plant I have a high chance of killing. I have a very green thumb in general, but I have my limits. So far, it has done well. I was excited that the specimen I bought had some visible buds.
Here is the plant label:
Those flower buds developed and opened into these beautiful cheery yellow blooms.
So far so good, but we'll see if I can ever get it to bloom again. I'll be happy if I can just keep this little guy alive.
