This picture is worth a thousand words! Elegant blue! Wide blue leaves.



A sieboldiana hybrid, one of the largest blue cultivars available. The huge leaves are lighter blue than most of this type and are nicely puckered with lots of substance. Beautiful near-white flowers. Rapid grower. Slug resistant. Use as a specimen alone or in the background of your garden. A mature clump can get over 5' wide!
