This is a very distinct almost shrubby sage from southern Mexico with impossibly vivid scarlet flowers among rounded fresh green leaves. In a group with, one might say, almost too many ornamental plants, it really stands out.
I have received mixed messages regarding it hardiness. The top growth is destroyed by frost but the roots move about quite freely and given a good mulch it might well regenerate. At any rate it's easy from cuttings and is a good pot plant as long as it doesn't freeze through. For well-drained soil in sun.
