Plant Care
Pruning is rarely needed, but may be trimmed in spring.
A very adaptable, durable species, H. kalianum will tolerate most conditions including dry soils, poorly-drained soils, and compacted ones. Blues Festival™ was selected for its rich blue-green foliage, long bloom time, and compact habit. A good native plant that is adored by bees, it flowers in July and August. It is a real workhorse for landscapes.
