Hosta Tiny Gems will form a miniature mound of just 7"-9" in height, with a spread of up to 20". What can we say about this one? A great new addition to the miniature Hosta garden. It's been a long time coming, a vigorous mound of thick blue foliage. Finally, it's here. It's called Hosta Tiny Gems. The leaves are pointed, folded and wavy and a lovely blue, somewhat heart-shaped. This is a great new Hosta for the miniature Hosta garden. Pale lavender flowers on perfectly proportioned scapes in summer.
