Heuchera richardsonii 

Prairie Alumroot 

• Well drained soils with an organic layer (leaf litter for example)
• Full Sun to Partial Shade
• 24” tall 8” to 16” wide
• Spring to Early Summer blooms
• Ontario Native, Thrives in open woodlands or meadows

New to me, grown from seeds from Prairie Moon Nursery https://www.prairiemoon.com/heuchera-richardsonii-prairie-alumroot-prairie-moon-nursery.html 

A spring blooming native heuchera that is described as having some naturally occurring variability of bloom and foliage colour, I suspect that these are one of the parent species of a lot of the fancy coralbell cultivars that have become popular over the last couple of decades.

Please check out the Prairie Moon listing at the link above for more details.
