Perovskia atriplicifolia
is a great plant for the sunny perennial or shrubby border. The soft
grey leaves and blue flowers are showy for a long time in the
garden. Not much that winter can throw out will ever present a
problem for this hardy plant. Perovskia atriplicifolia can take
Winter conditions in zone 3. Even if the plants don't die back in
our mild climate, I still cut the Russian Sage nearly to the ground each
winter. This hard trimming clears out the previous years branches
which die back to near the base regardless. Reasonable drainage is
about the only rigid requirement.
