Recently on a stroll thru a retail garden center I came across a tray full of salvia greggii san antonio. At least that's what they were all marked. But the flowers on these salvia were a solid coral pink color. Would this be a case of the nursery mislabeling their product or do the san antonios (which I thought were bicolors) revert to solid colors (like s. microphylla Hot Lips is known to do)?
