Cusick’s Draba: A Rare Pacific Northwest Gem for Your Rock Garden
If you’re a gardener who loves discovering hidden treasures of the plant world, let me introduce you to Cusick’s draba (Draba cusickii var. cusickii). This unassuming little perennial might not win any flashy flower contests, but it’s got character, charm, and a story that makes it worth knowing about.
What Makes Cusick’s Draba Special
Cusick’s draba is a native forb – essentially a non-woody perennial plant that hugs close to the ground. Think of it as nature’s way of creating a living cushion. This little plant has adapted to some pretty tough conditions, which makes it both fascinating and surprisingly useful for certain garden situations.
As a perennial, this plant comes back year after year, slowly building its compact, mat-like presence. It belongs to the mustard family, and while it shares some DNA with your garden cabbage, it’s taken a completely different path in life – choosing mountain slopes over vegetable patches.
Where Does It Call Home?
This native beauty is found exclusively in Oregon, making it a true Pacific Northwest endemic. It’s adapted to the unique climate and soil conditions of this region, which tells us a lot about what it needs to thrive in our gardens.
A Word of Caution: This Plant is Rare
Important: Cusick’s draba has a conservation status that indicates it’s not exactly common in the wild. If you’re interested in growing this plant, please make sure you source it responsibly from reputable native plant nurseries that propagate their own stock rather than wild-collecting. Never dig plants from the wild – this helps protect the remaining natural populations.
