Sweetscented Biscuitroot: A Hidden Gem for Pacific Northwest Gardens

If you’re looking for a charming native plant that brings both beauty and ecological value to your Pacific Northwest garden, let me introduce you to sweetscented biscuitroot (Lomatium serpentinum). This delightful little perennial might not be the showiest plant in your garden, but it’s definitely one of the most rewarding to grow.

What Makes Sweetscented Biscuitroot Special?

Sweetscented biscuitroot is a native forb that belongs to the carrot family, and it’s perfectly adapted to life in Idaho, Oregon, and Washington. As a perennial herb, it lacks the woody stems of shrubs and trees, instead growing as a soft-stemmed plant that dies back to the ground each winter and returns faithfully each spring.

This native gem grows naturally across the Pacific Northwest, thriving in the region’s unique climate and soil conditions. You’ll find it scattered throughout Idaho, Oregon, and Washington, where it has been quietly supporting local ecosystems for thousands of years.

  • Low maintenance: Once established, it’s incredibly drought tolerant

  • Early blooms: Provides nectar when many other plants are still sleeping
