Sorry, wish I could help. I was originally looking for those to plant and I couldn't find them. I had seen then in "Landscape Plants for the Arizona Desert" book that was given to me, but had no luck so I bought "Green Cloud" and I've still gotten pretty lavender blooms. Plus, that's seems to be something you can find any where. I'll keep my out though.
Ditto with me! Same book, and I love my green clouds. But my parents have something else in their yard, probably Chihuahuan or Texas sage. They tend to bloom all at once.
I'll keep my out for them and let you know if I see any. I am loving my green clouds, but it would have been nice to have something bloom all at once. However, I was in a rush to plant them before the true summer arrived, but I'm still very please with what I have.
Look for the cultivar names: Rio Bravo and Laura's Legacy are that species.
Thanks for the heads up on alternative names. They change so fast when people are out there cross breeding.
My nursery tells me I am looking for Rio Bravo subspecies. They are ordering two for me
Mountain States Wholesale Nursery grows two varieties fo Langmann's sage; Lynn's Legacy and Rio Bravo. Lynn's Legacy blooms more frequently than Rio Bravo and grows more slowly (less pruning). Here's the link to information on Lynn's Legacy - http://mswn.com/Plant%20Info%20Sheets/Leucophyllum%20langmaniae%20LL.pdf
Details on Rio Bravo are in the link below.
Here is a link that might be useful: Rio Bravo - Leucophyllum langmaniae
Rio Bravo and Lynn's Legacy are apparently very similar. LL is a little lighter green, RB doesn't need pruning - forms it's own tight ball. The nursery has apparently forgotten to order for me. I can get them in Phoenix next time I am up there.
