Sundew Black Sea Comfrey as it is also known, is a herbaceous perennial groundcover with gold/chartreuse foliage. White throated blue flowers appear in early spring, before the stunning foliage makes its appearance. A great weed-smothering ground cover. Prefers partial shade to full shade, but does tolerate full sun (but doesn't perform as well). Grows to approx 30 - 45cm.
