BLUE DIDDLEY® Chastetree

Zone: 5, 6, 7, 8, 9 Exposure: Full Sun Height: 3-6' Width/Spread: 3-6'

This dwarf chaste-tree is good for perennial gardens and mixed borders. In milder climates, it will be a small tree or shrub; in colder climates it behaves more like a perennial and will often die back to the ground. It has interesting texture, and brings cool blue color to summer gardens with its spikes of lavender-blue flowers.

Light: Needs full sun exposure to thrive, which is a minimum of six hours of light.

Soil: Grows well in any soil type that is well draining.

Water: Has less than average water needs, as it is very drought tolerant once it’s established.

Fertilizing: You can apply a granular fertilizer formulated for flowering shrubs in the springtime.

Pruning: In cooler northern climates, it can be treated like an herbaceous perennial. In warmer southern climates, it won’t die back as much. You can then prune it to shape in the spring, cutting out any parts that didn’t survive.
