Geum coccineum 'Borisii'

Masses of single, long-lasting, bright orange single flowers with yellow stamens are produced in clusters on long, upright stems throughout spring, summer and well into the autumn - I find some years it hardly stops flowering. It is a  clump-forming perennial forming a neat rosette of hairy, fresh green leaves.
Brilliant for growing in groups at the front of a mixed or herbaceous border
