It performs best in full to partial sun and is appreciative of moist, well-drained soil. The sky blue flowers appear in early spring above the clean, dark green foliage. Try planting 'Short Stack' in a mess and along bed edges for a winning display.

(4 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11
