The Rhodora or Canadian rosebay from Eastern N America makes a dwarf to small deciduous, very hardy upright shrub, 50cm to 1.2m high. Flowering on the naked stems in early April the dainty purple-pink flowers in clusters of 2 to 6 together are distinct in their almost filigree form, leading early botanists to consider it worthy of its own genus, Rhodora. The sea-green foliage, which emerges after the flowers, is narrowly oval. Rarely offered for sale in the UK, this is a well known flowering plant of the NE USA and E Canada. For moist peaty acid soil.
