Know before you buy
This Hosta thrives in partial to full shade. It performs best in areas protected from the harsh afternoon sun, which helps the leaves maintain their signature powdery blue color.
Yes, 'Prairie Sky' is very hardy and is rated for USDA zones 3 through 9. It can withstand temperatures as low as those found in zone 3a, making it a reliable perennial for northern gardens.
Since this Hosta reaches a mature spread of about 30 inches, you should space them 30 inches apart from the center of one plant to the next. This allows enough room for the dense, mounding foliage to develop fully without overcrowding.
No, 'Prairie Sky' is not considered deer or pest resistant. If you live in an area with high deer activity, you may need to use protective netting or repellent sprays to keep them from grazing on the foliage.
It prefers average to moist, well-draining soil. Consistent moisture is key to keeping the foliage healthy and preventing the leaves from drying out during the summer months.
The foliage mound typically reaches about 14 inches in height. When the plant is in bloom during the summer, the flower spikes will extend up to 24 inches tall.
