Light Requirements
• Full sun (6 or more hours of direct sunlight a day) to partial shade (2 to 6 hours of direct sunlight part of the day).
Soil Preference
• Highly versatile, tolerating a large range of soil types including poor, sandy, and clay textures.
• Adapts to moist, dry, or wet soils, managing drainage conditions that range from occasionally dry to occasionally wet.
• Thrives in an acidic (< 6.0) to neutral (6.0–8.0) soil pH environment.
Wildlife Benefit
• Larval Host: Critical host plant for multiple species, including the California and southern dogfaces, Silver-spotted Skipper (Epargyreus clarus), Gray Hairstreak, and Hoary Edge butterflies.
• Pollinator Forage: The narrow, fragrant purple and gold flower racemes attract butterflies, nectar-bees, and various other pollinating insects.
• Mammal Forage: The fine-textured, pinnately compound foliage is browsed by small mammals.
Human Uses
• Landscape & Screening: Reaches a mature size of 4 to 15 feet tall and spreads up to 15 feet wide. It is used as a functional barrier, hedge, or privacy screen, and works well massed in woodland gardens, bog gardens, rain gardens, and stormwater systems.
• Erosion & Restoration: Because of its rapid growth rate and horizontal, suckering habit, it is heavily used for erosion control on roadsides, steep slopes, banks, and riparian zones.
• Crafts: Utilized historically and modernly as a native dye plant asset.
Resistance to Challenges
• Mammals: Highly deer resistant.
• Harsh Environments: Showcases strong natural resistance to poor soil, dry soil, wet soil, frost, and overall poor site conditions.
Note on Management: It can become weedy because it spreads easily via seeds and root suckers to form dense thickets.
