Easy to grow, though short lived (2-3 years) this prolific seeder will never really disappear from your garden. A hybrid by two UNKNOWN species one from South America and the other one is anyones guess. First year its a rosette of spoon shaped green leaves. The following year it dramatically rises to 3′ in spring/summer and produces clouds of rounded steel blue flowers. Very pretty and airy and you must mix it with a nice tall ornamental grass for the ultimate effect. As I mentioned it then seeds around. Interesting cut flower. Drought tolerant and best in full sun. High deer resistance.
