Cynoglossum creticum

A study in silver and blue, this biennial spends its first season as a rosette of large felted tongue-shaped leaves.  In spring of year two, one-sided clusters of blue, dark-veined flowers are bone above the flowers on branching stems.  As with most short-lived borages, it keeps going via self-sowing -- possibly aggressively in mild-winter regions.

Sun; average to dry, well-drained soil (drought tolerant); 24"x18"; late spring; Zone 6

Propagated from seed; deep 3.5-inch pots
