If you’re passionate about California native plants and conservation gardening, you’ve probably heard of checkerblooms. But have you met the rare and special Pt. Reyes checkerbloom? This delicate perennial deserves a closer look from gardeners who want to make a real difference in preserving our native plant heritage.
Meet the Pt. Reyes Checkerbloom
Scientifically known as Sidalcea calycosa rhizomata, the Pt. Reyes checkerbloom is a California native that belongs to the mallow family. You might also see it referred to by its synonym, Sidalcea rhizomata. This charming plant is what botanists call a forb – basically a non-woody perennial that dies back to ground level each year, then emerges fresh each growing season from buds at or below the soil surface.
Where Does It Call Home?
This special checkerbloom is exclusively Californian, making it a true Golden State endemic. Its native range is quite limited, which contributes to its conservation status that gardeners should be aware of.
