Know before you buy
Yes, staking is highly recommended. Because these plants can reach up to 6 feet in height, their tall, graceful spikes are susceptible to bending or breaking in strong winds or heavy rain.
To promote a second flush of flowers in early fall, cut the main flower stalks back to the ground immediately after the first summer bloom cycle finishes.
This cultivar performs best in very fertile, well-drained, and moist soil. It prefers a near-neutral pH level to support its vigorous growth.
Yes, 'Blue Nile' is considered deer resistant, making it a reliable choice for gardens where wildlife pressure is a concern.
Absolutely. The vivid blue blooms are excellent for attracting bees and butterflies, making it a functional and beautiful addition to a pollinator-friendly landscape.
For a classic June display, pair 'Blue Nile' with peonies or roses. Their contrasting textures and complementary bloom times create a sophisticated look for sunny borders.
