Could anyone suggest low maintenance ideas for planting under Himalayan birch trees in dry shade? Made worse by sandy soil. The area is fairly small (2m square). It looks nice in spring but gets manky by late summer.
I'm thinking:
Epimedium (vigorous ones)
Bergenia?
Vinca?
Euphorbia amygdaloides
Small shrubs?
Already have ferns (looking manky), hellebore, and foxgloves but Japanese anemones and wood aster failed to establish 😞
Many thanks for any ideas
