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.
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.
