WILDLIFE & INSECTS
Bees
- The fragrant early season blooms attract a range of pollinators including native bumblebees, mason bees, and honeybees when few other sources are available.
Butterflies
- Early blooming flowers provide nectar for overwintered species such as Mourning Cloaks and Spring Azures.
Beneficial Insects
- Small flower clusters attract predatory insects like lacewings and hoverflies which contribute to natural pest control.

- Space 3 - 5 ft apart to allow for mature width and natural mounded form development.
Landscape Placement:
- Excellent as a foundation shrub, border accent, or part of a mixed native hedge. Performs well in woodland edges or moist, acidic soils of naturalized gardens.
