So I purchased this Dudleya from a local San Jose nursery.  The customer service rep told me that it was the Dudleya Britonii after looking the plant up in their purchase records.  I chuckled because it looks nothing like that!  In the last picture below, you can see my mystery plant photographed with a Dudleya Pulverulenta which is commonly confused with the Dudleya Britonnii, so you can tell how vastly different the plants are.

Update: After doing research online, I think this plant looks very similar to Dudleya Ingens.  I’m still going to continue to research to make sure though! 🙂
