Bigelow’s Willow: A Graceful Native Shrub for California and Oregon Gardens

If you’re looking for a graceful native shrub that brings year-round beauty and wildlife value to your garden, let me introduce you to Bigelow’s willow (Salix lasiolepis var. bigelovii). This lovely willow variety might not be the showiest plant in the nursery, but it’s a quiet champion that deserves serious consideration for the right garden setting.

What Makes Bigelow’s Willow Special?

Bigelow’s willow is a perennial shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall. What sets this native apart is its elegant form and subtle beauty. The narrow leaves have a distinctive silvery-green appearance with fuzzy undersides that catch the light beautifully, creating movement and shimmer in the garden breeze.

In spring, this willow produces charming yellow-green catkins that not only add visual interest but also provide crucial early-season nectar and pollen for bees and other pollinators when few other plants are blooming.

Where Does Bigelow’s Willow Call Home?

This native beauty is perfectly at home in California and Oregon, where it naturally grows in coastal and inland areas. As a true native of the lower 48 states, it’s beautifully adapted to the unique growing conditions of the Pacific Coast region.

Is This the Right Plant for Your Garden?

Bigelow’s willow shines in several garden situations:

  • Native gardens: Perfect for gardeners wanting to support local ecosystems
  • Water-wise landscapes: Once established, it tolerates drought conditions well
  • Restoration projects: Excellent for erosion control and riparian restoration
  • Wildlife gardens: Provides habitat and food sources for local wildlife
  • Natural screening: Creates attractive, informal barriers or backdrop plantings

Important note: This variety has a somewhat unclear conservation status, so if you decide to plant it, make sure to source your plants from reputable native plant nurseries that practice responsible propagation.

Ideal Growing Conditions

This adaptable native thrives in USDA hardiness zones 7-10. It’s quite flexible about growing conditions, accepting everything from moist soils to seasonally dry areas. Give it full sun to partial shade, and it’ll be happy in various soil types.

Planting and Care Tips

The beauty of native plants like Bigelow’s willow is that they’re generally low-maintenance once established. Here’s how to set yours up for success:

  • Watering: Provide regular water the first year, then reduce to winter moisture supplementation

Wildlife and Pollinator Benefits

One of the biggest reasons to consider Bigelow’s willow is its value to local wildlife.
