USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Plant Information

24-48" tall and 24-48" wide. Caryopteris × clandonensis 'Longwood Blue' is a fantastic mid-sized shrub for landscape beds, perennial borders, and as a mass foundation planting. Hardy in zones 5-9, ‘Longwood Blue’ can be pruned hard to the ground each year to produce evenly-rounded, fresh growth. In colder zones, low winter temperatures can kill the top growth to the ground; otherwise, cut plants back in the spring. Plant in full sun in average to moist, but well-drained soil. 'Longwood Blue' is drought tolerant once established. For maximum impact, plant in groups of three or more. Will sometimes sucker and spread in warmer climates.
