Coville’s Purplemat: A Little-Known Native California Annual
Meet Coville’s purplemat (Nama demissum var. covillei), a charming yet elusive native California annual that most gardeners have probably never heard of. This small forb belongs to the borage family and represents one of nature’s more modest offerings in the native plant world.
What Makes Coville’s Purplemat Special
As its botanical name suggests, Nama demissum var. covillei is a variety of the broader demissum species, named after the botanist Frederick Coville. This little plant embodies the small but mighty philosophy of native gardening – it may not steal the show, but it plays an important supporting role in California’s natural ecosystems.
Coville’s purplemat is classified as a forb, which simply means it’s a non-woody flowering plant. As an annual, it completes its entire life cycle in one growing season, making it a temporary but renewable addition to any garden space.
Where You’ll Find This Native
This variety is native to the lower 48 states, with its natural range specifically limited to California. While many native plants have expansive ranges, Coville’s purplemat appears to be quite the California specialist, making it a true regional treasure.

Should You Grow Coville’s Purplemat?
Here’s where things get interesting – and a bit challenging. While Coville’s purplemat is undoubtedly a legitimate native plant worthy of conservation and appreciation, finding detailed growing information specifically for this variety is like searching for a needle in a haystack. This rarity of information suggests a few possibilities:
- It may have very specific habitat requirements that make cultivation challenging
- It might be naturally uncommon, even within its native range
- Seeds or plants may be difficult to source commercially
- It could be so specialized that it hasn’t caught the attention of the broader native plant gardening community
The Reality of Growing Rare Natives
If you’re determined to include Coville’s purplemat in your garden, you’ll likely need to become something of a plant detective. Since specific growing conditions, hardiness zones, and care requirements for this variety aren’t well-documented in popular gardening resources, you might consider:
- Contacting local native plant societies in California
- Reaching out to botanical gardens or universities with California native plant programs
- Connecting with specialized native seed suppliers
- Observing the plant in its natural habitat, if accessible
Alternative Approaches
Given the challenges of growing this specific variety, you might consider exploring other members of the Nama genus or related native California annuals that offer similar ecological benefits but with more available growing information. Sometimes the best approach to supporting native biodiversity is choosing plants that you can successfully establish and maintain.
