Most soil types are tolerated well, so it is quite versatile. However, this salvia may be prone to frost damage and it can be useful to prune the stems in winter and protect the roots with pea straw. Black Knight is known to be deciduous in colder areas of the world, but the plant will return in spring. Since it is a large growing salvia it is often best suited to the back border or as a fence screen.
