Dryas x suendermannii AGM Dryas x suendermannii AGM Dryas x suendermannii AGM Dryas x suendermannii Easy form of Mountain Avens £2.75 Out of stock. A more easily grown hybrid form of our Mountain Avens. The white, yellow-centred flowers appear in late spring, dangling on short stems and soon followed by very pretty, fluffy seed heads. The leaves are also attractive - almost evergreen, like tiny Oak leaves with silver undersides. This can form wide-spreading carpets where allowed and makes good ground cover. About 12cm (5") high.
