Boat lily

Tradescantia spathacea | Also known as: Moses-in-the-boat, Spiderwort Rhoeo spathacea, Rhoeo discolor, | Rating: 0 votes | Print / Pdf

At first, tradescantia spathacea looks like any other lush groundcover option, but the vivid purple-coloured underside of its waxy, grey-green, sword-shaped leaves, make it a far more attractive plant. Commonly known as moses-in-the-cradle, this clump-forming evergreen perennial produces tiny, three-petalled white blossoms in purple bracts that seem to be cradled in leaf bases, thus the reference in its name. Moses-in-the-cradle thrives in moist but well-drained loamy or sandy soil, preferably in partial shade, and while it dislikes frost, it’ll simply retreat before returning to its glory as temperatures rise. Wet conditions can be too much to handle, so they are ideally suited to gravel beds and other fast draining locations.
