This cultivar of ours, Elk Lemon Light, has more of the characteristics of a Salvia greggii than any other yellowish variety of this sort. Hence it has done well in Zone 7 winters in many places - northern Georgia, Kentucky, Arizona, Washington, DC, etc. Out of bloom it strongly resembles a typical S. greggii. Yellow clones are never as strong or fast growing, and more difficult to propagate as well.
