Krossa Regal Hosta
Hosta ‘Krossa Regal’ · a vase-shaped blue hosta
A vase-shaped hosta with frosty blue-green, wavy leaves held upright, giving structure that rounded hostas can't, and its lavender flower spikes rise far above the leaves and draw hummingbirds. The leaves green up by midsummer; protect it from deer, who find hostas delicious.
