  • Fall Colour: Foliage may take on subtle yellow or reddish-orange hues.
  • Bark: Slender, dark reddish-brown stems.

Garden Value:

A premier choice for flowering hedges, foundation plantings, or as a graceful specimen in a mixed shrub border. Its dense habit makes it an excellent backdrop for smaller perennials.

Wildlife & Human Value:

  • Wildlife: Provides an abundant nectar source for early-season pollinators.
  • Human: High ornamental value for curb appeal and low-maintenance privacy screening.

Planting & Care Guide

Planting Considerations:

Best planted in spring or fall. Space 3–4 feet apart for a continuous hedge. Its non-invasive roots make it safe for planting near sidewalks.

Care:

  • Light Requirements: Thrives in full sun for the best floral display but tolerates light shade.
  • Moisture Requirements: Requires average, well-drained moisture; avoid letting the soil sit in water.
  • Maintenance & Fertilization: Apply a balanced fertilizer in early spring. Prune immediately after flowering to maintain its shape and ensure a heavy bloom the following year.

Tolerances:

Deer, Rabbits, Drought, Clay Soil, Urban Pollution.

Tips For Success:

To keep the plant vigorous and prevent it from becoming "leggy," prune out a few of the oldest stems at ground level every few years after flowering.
