Whenever we identify a plant as being discovered by Texas plantsman Greg Grant, you can almost guarantee it will perform well in your Oklahoma garden. Such is the case with Henry Duelberg Salvia. We have grown varieties of Salvia farinacea for years with great success. They are tough sun loving plants that flower all season. You can think of this one as sort of like a Victoria Blue Salvia on steroids. It's a bigger more robust plant that produces more flowers. Greg found this selection in a small central Texas cemetery. He named it after the nearest tombstone, that of a Mr. Henry Duelberg. It was later chosen as a Texas Superstar by the Texas A&M plant branding program.
