Salvia subrotunda is very tender, so be careful of cold nights. Even in the high 30s it starts to say, "I'm NOT happy". It grows for us very rapidly to six or eight feet, and is a hummer magnet. We won't even start to propagate these until April, as most folks can plant them in May/June and have a great plant in a month or so.
S. iodantha is highly variable from seed. We have grown out a large number and only a few are worthwhile, IMHO. We have a clone that is much better than average, but it took a lot of trying. The cultivar 'Louis Sasso' is truly fine, and quite distinct. Both of ours are in wildly full bloom now.
Such fun!
