Perle and Red

I happened to be in Home Depot today so picked up the Echeveria 'Perle von Nurnberg' I thought I bought four days ago. Here are the imposter 'Red Sky' and 'Perle' side by side. 'Perle' is by far the largest succulent I have planted in a four-inch pot, but I didn't have any six-inchers today and I didn't want to go up to eight.

Echeveria Red Sky and Echeveria Perle von Nurnberg

These two are closely related and do (or did) look almost alike. 'Red Sky' seems to be a lighter, more reddish color, but that may have developed in just the past few days from getting a lot more light (grow lights and sun) than on a shelf at Home Depot. I think the plant on the right is the same one I had in my hand four days ago, and I recall the color of the two plants being exactly the same then. It will be interesting to see what the two look like next week after 'Perle' catches some rays. Anyway, 'Perle' can be crossed off my bucket list.
