Salvia 'Penny's Smile'

This new introduction is interesting. Last year I found a few seeds on S. 'Silkes Dream'. This particular seedling was the most vigorous, and the foliage seemed the same as its parent, unlike another which seems to have reverted back to a small orange microphylla. 'Penny's Smile' is now 4 ft. tall, and totally upright, unlike the somewhat sprawling tendency of SD. The flowers are a gorgeous shade of pink, and are more than one inch across. I have no idea what the other parent is, as several greggiis/microphyllas were in close proximity, other species also. I suppose a hybrid, such as SD, can cross with another species?
