Itea virginica |
Itea virginica, commonly known as Virginia willow or Virginia sweetspire, is a small North American flowering shrub that grows in low-lying woods and wetland margins. Virginia willow is a member of the Iteaceae family, and native to the southeast United States.[1] Itea virginica has small flowers on pendulous racemes.[2]
Depending on location, the species will bloom in late spring to early summer. It prefers moist rich soil, but it can tolerate a wide range of soil types. When Virginia willow is used in horticulture it can form large colonies and may form dense root suckers, making the shrub hard to remove.
Description[]
Itea virginica is a deciduous shrub that grows to 2.5 m (8.2 ft) tall and 1.5 m (4.9 ft) broad, with alternate, simple leaves on arching stems. The flowers are white or cream, borne in downward pointing slightly curved spikes, in summer. It is a multi-stemmed, suckering and colonizing plant, with the stems branching infrequently except at the tops. In favorable conditions it may become semi-evergreen. The leaves turn shades of red in fall (autumn). It is hardy down to at least −15 °C (5 °F).[3]
Conservation[]
Itea virginica has a current IUCN status of Least Concern.[4] However, Itea virginica is considered extirpated in Pennsylvania and endangered in Indiana.
Taxonomy[]
Itea virginica belongs to the Iteaceae, a family of deciduous and evergreen shrubs.[5] It is the only species in its genus in North America; most Itea species are from east Asia. Some authors have historically placed Virginia sweetspire in the Grossulariaceae or Saxifragaceae families.[6]
Horticulture[]
In cultivation in the UK the cultivar ‘Henry’s Garnet’ has gained the Royal Horticultural Society’s Award of Garden Merit.[7][8] Itea virginica is used as a native ornamental landscape plant in North America, and numerous cultivars have been named.[9] The flowers attract pollinators, and the shrub can be used for erosion control.[10]
