Blue LagoonLarge flower trusses, more blue than purple, have a dark eye in each flower. The plant is very vigorous, growing to 6 8 ft. tall and just as wide in 10 years. A must have for the purple lovers! Many rhododendrons are tricky to keep thriving but not Blue Lagoon. This is an excellent choice for beginning gardeners, landscapers or people who want a gorgeous statement plant without any fuss. Blue Lagoon will grow like a weed to fill in your blank space
