Names

The Latin specific epithet pallida means "pale".[6]

Description

Tradescantia pallida is an evergreen perennial plant of scrambling stature. It is distinguished by elongated, pointed leaves - themselves glaucous green, fringed with red or purple - and bearing small, sterile three-petaled flowers of white, pink or purple. Plants are top-killed by moderate frosts, but will often sprout back from roots.[7]

Cultivation

Widely used as an ornamental plant in gardens and borders, as a ground cover, hanging plant, or - particularly in colder climates where it cannot survive the winter season - houseplant, it is propagated easily by cuttings (the stems are visibly segmented and roots will frequently grow from the joints).

As a houseplant, T. pallida has been judged exceptionally effective at improving indoor air quality by filtering out volatile organic compounds, a class of common pollutants and respiratory irritants, an effect known as phytoremediation.[8]

Numerous cultivars are available, of which 'Purpurea' with purple foliage has gained the Royal Horticultural Society's Award of Garden Merit.[9][10]
