Grandma's pride and joy, this cottage garden favorite can reach 6-8 feet tall and provide single blooms in shades of rose, pink, white, and salmon. Ideal for screening or for back of the border, Indian Spring needs full sun and rich, well drained soil. After blooms fade prune plants back to 6 inches from the ground and you will be rewarded with a new flush of blooms in the fall. Grandma would be so proud! Hardy to zone 3. Pkt. 100
