The Ledger in Lakeland Florida has this to say:
Among the finest succulents for windowsills are Echeveria species and hybrids.
Now I suppose we could argue about what is meant by the phrase, “among the finest” but that would be pedantic. Leave us to say that within a broad range of possible finest’s, Echeverias could be on a conceivable list. Like this one.
Echeveria pulidonis would certainly make a good windowsill plant, and I would put it on my list of the top 2000 finest succulents for windowsills, so sure – it qualifies!
