Anchusa azurea ( Italian Bugloss )
A sturdy, clumping perennial, reaching up to 6 ( rarely over 5 ) feet in height, that is native to southern Europe near the Mediterranean Sea.
The ovate leaves, up to 12 inches in length, are bright green. The bright blue flowers, up to 1 inch wide, are borne on upright spikes during early summer, often repeating into early autumn if deadheaded.
Hardy zones 3 to 7 in full sun to partial shade on just about any light, well drained soil. It is deer resistant but root rot can be a problem, especially during winter on poorly drained clay. It is heat tolerant but doesn't enjoy the high humidity of the southeastern U.S. Cut back hard during mid-summer for a fresh crop of foliage. Propagation is from division during autumn or early spring ( flowering is improved if clumps are divided every few years ). Non-cultivars can be sown from seed on site during spring.
