Hosta 'Guardian Angel'
[L] Large blue leaves have a lighter, misted, bluish-white center. The center color is most pronounced in the spring and depending on the location and growing conditions, the leaf can turn nearly solid blue by fall. The variegation holds best in bright, cool shade. The leaves are undulating and often show some puckering and gathering where the two colors meet. A mature Hosta 'Guardian Angel' is a spectacular sight to behold! Easy to grow and develops into a large, imposing plant with white flowers.
