The
1995 Perennial Plant of the Year! A true standout
in the garden. Spikes of intense blue flowers
are produced during summer above outstanding silvery
aromatic foliage. This one grows best in well-drained
soil. Cut back to about a foot above the ground
in late winter to keep plant full and encourage
more flowers in summer. |
