In the garden
Rodgersia pinnata 'Alba' originates from Sichuan and Yunnan in China and belongs to the Saxifragaceae family. It forms a substantial herbaceous clump to around 1.2 metres, with textured pinnate foliage topped by upright clusters of small white flowers. Flowering occurs June to July. Give it a sheltered shady spot; the plant performs well in partial to full shade and prefers soil that remains moist but drains freely. It tolerates a wide range of soil pH from acidic to alkaline, so focus on providing a rich, humus-rich growing medium and regular moisture rather than adjusting pH. The hardiness rating H5 indicates it is hardy in the UK and will survive typical winter conditions when established. Use Rodgersia pinnata 'Alba' where leaf texture and summer vertical flowers are needed: mixed shade borders, woodland gardens and alongside ponds or streams are ideal. Allow space for the clump to develop without crowding by sun-loving plants that prefer drier ground. The upright white panicles appear above the foliage in June to July, offering a clear seasonal marker and contrast with darker-leaved companions.
