I'm trying to put together a list of New World salvias to grow on a shady deck for a nature center. The spot doesn't get morning sun and from mid day on it recieves roughly 50% sun because there is a lath roof. Three I currently have are miniata, chiapensis, and buchananii. The first should do OK in large pots, it does at home. But what about the latter two, is this likely to be too much shade? And are there others I should be considering? That is a lot of questions, but I want a display of thriving plants, not struggling experiments.
