Tradescantia ×andersoniana ‘Bilberry Ice’ – Spiderwort – 5-Pint

From North Carolia Extension Gardener Toolbox:

A hardy, herbaceous perennial, spiderwort … is grown for its showy blooms and foliage. It is the most common spiderwort in cultivation and is a putative hybrid between the common spiderwort (T. virginiana) and the Ohio spiderwort (T. ohiensis). Many plants cultivated under the name T. virginiana are, in fact, this hybrid, and even trained professionals have difficulty distinguishing the hybrid from its putative parents. The hybrid epithet is not recognized as validly published, but it is commonly used in the trade. The hybrid epithet honors Edgar S. Anderson (1897–1969), an American botanist who studied the group and published extensively on its cytology and taxonomy.
