Full nameTradescantia (Andersoniana Group) ‘Rubra’.
Name statusAccepted, the valid name for a unique cultivar.

Established by Wrede (1819, p. 55). Because it was published before 1959, the Latin name with no description can be accepted (Brickell et al., 2016, Arts. 21.11, 27.1).

The name was originally spelled ‘Rubro’ (Wrede, 1819, p. 55), but this is correct to match the grammatical gender of the genus (Brickell et al., 2016, Art. 21.8).
ClassificationLike other hardy garden hybrids, it is now placed in the Andersoniana Group. These hybrids are sometimes mislabelled as Tradescantia virginiana or the invalid botanical hybrid Tradescantia × andersoniana.
Legal protectionNone.
AvailabilityMass-produced and widely available.
