Easy to grow in the garden and from seeds, this North American Geum is an absolute a delight!  An unpretentious, care free plant in most locations; sun and good drainage required. Best when planted in large numbers for the ‘smoky’ effect of the feathery seed heads (Prairie Smoke ;) in the summer.

Geum triflorum – Prairie Smoke, Old Man’s wiskers; rosy-red, nodding calyces/flowers, followed by feathery seed heads; the compact, ferny looking foliage will become reddish in the fall.

Propagation from seeds: I did a whole bunch last year – sown in the fall and left outside (cold/moist stratification) and the germination was excellent; I planted the seedlings in the garden by late fall.
The grown up clumps can be easily divided every few years.

Note: Other sources indicate sowing at warm.
