Sierra Milkwort: A Rare California Native Worth Discovering
If you’re a native plant enthusiast looking for something truly unique for your California garden, Sierra milkwort (Polygala cornuta var. cornuta) might just be the hidden gem you’ve been searching for. This perennial shrub represents one of nature’s more elusive offerings, and while information about this specific variety is somewhat scarce, its native heritage makes it worth considering for the right garden setting.
What Makes Sierra Milkwort Special
Sierra milkwort belongs to the milkwort family and grows as a multi-stemmed woody shrub. Like most shrubs, it typically develops several stems from or near the ground and usually stays under 13-16 feet in height, though environmental conditions can influence its final size and form. As a perennial, it’s built to last, returning year after year once established.
Native Status and Where It Grows
This plant is a true California native, naturally occurring within the lower 48 states but specifically calling the Golden State home. Its limited geographic distribution to California makes it a special addition for gardeners committed to supporting local ecosystems and preserving regional biodiversity.
