Plant Information

Excellent California selection of Chaste tree with thicker, bluer flowers. Large growing shrub with aromatic finely divided leaves in mid-July in PDX spires of blue flowers erupt from each branch tip. It remains in bloom for 3-4 weeks. And if you remove spent flowers more will appear. Full sun and poor to average well drained soil. No summer water when established. Attains tree-like status with great age. May be pruned back hard in spring to contain the ultimate size. Blooms on new wood. Long lived and hardy below 0ºF. Leaves appear late in spring- often not until mid-May. Be patient. Loved by pollinators and bumble bees specifically. A shrub in full bloom will be a haze of drunken bumbles who after a day of working will often fall asleep in the flowers of this shrub. Tolerates the hottest sites and is very long lived. Plant type: Shrub | Sun exposure: Full Sun Biome: Deer Resistance, Hot Aspects, Low Water/No Water | USDA Hardiness zone: Zn6a -5º to -10ºF Foliage color: Mid Green | Foliage season: Winter Deciduous
