Scarlet Cinquefoil: A Hidden Gem of the Southwest
If you’re looking to add a touch of authentic southwestern charm to your garden, let me introduce you to scarlet cinquefoil (Potentilla thurberi var. atrorubens). This delightful native perennial might not be on every gardener’s radar, but it deserves a spot in gardens across Arizona and New Mexico—and here’s why.
What Makes Scarlet Cinquefoil Special?
Scarlet cinquefoil is a true native of the American Southwest, naturally occurring in Arizona and New Mexico. As its common name suggests, this plant likely showcases beautiful reddish blooms that can add a pop of color to native plant gardens. The variety name atrorubens literally means dark red, hinting at the rich coloration that makes this plant so appealing.
This herbaceous perennial belongs to the rose family and grows as a forb—essentially a non-woody flowering plant that comes back year after year. Unlike shrubs or trees, it doesn’t develop thick, woody stems, making it perfect for layering in garden designs.
Where You’ll Find It Growing Wild
In nature, you can spot scarlet cinquefoil growing in Arizona and New Mexico, where it has adapted to the unique climate and soil conditions of the Southwest. This limited native range makes it a true regional specialty.
A Word of Caution: Rarity Matters
Here’s something important every responsible gardener should know: scarlet cinquefoil has a conservation status that suggests it may be uncommon in the wild. Before adding this beauty to your garden, make sure you’re sourcing it from reputable native plant nurseries that propagate their plants rather than collecting from wild populations. We want to enjoy these plants in our gardens while also protecting them in their natural habitats.
