Identification and Habitat

Purple mountain saxifrage is a low-growing, small, matted plant with dark green rounded and scaly leaves earning it the name French Knot. It has many small 5-petaled, cup-shaped flowers that are magenta to purple in color. The flowers are about 1-1.5 cm in diameter, growing on short stalks rising slightly above the leaves. The plant is cushion-like and may grow to about 5 cm in height. The leaves are 2-4 mm long. The taproot may be very long, up to 50 cm or 20 in.

The plant grows in gravelly slopes, talus, and rocky ridges where there is decent moisture. I’ve often seen it growing in rocky glacier moraines where there is little soil growing between cracks in the rocks. It blooms very early, following snowmelt.

This site needs your help!

I'm currently trying to raise money to secure hosting and other website fees for the next 3 years. If you didn't know, this website is a one-man show and it's a lot of work and money to put together. I want to keep churning out new content and guides and keep everything free, but it would be incredibly helpful and mean a lot if you could make a contribution to keep it going. Even if you can't contribute, sharing posts or the Indiegogo campaign on social media will help make a big impact. Thank you!
