Symphytum Rubrum (Red Comfrey)

Symphytum ‘Rubrum’ (Red Comfrey) is a rhizomatous perennial forming a low mound of softly hairy, lance-shaped, dark green leaves. In late spring to early summer, nodding, tubular bell-shaped, deep crimson red flowers appear in drooping clusters. Slowly spreading and less vigorous than most comfreys, Red Comfrey may be used as a ground cover.

Slowly spreading and less vigorous than most comfreys, Red Comfrey may be used as a ground cover. It is also an excellent subject for the wildflower garden. A most suitable plant for moist areas in dappled shade.

  • Grows up to 15-18 in. tall (37-45 cm) and 18 in. wide (45 cm). Once established, Comfrey can be very difficult to dig out.
  • Thrives in full sun or part shade in moderately fertile, moist, well-drained soils. Appreciates some afternoon shade in hot summer climates.
  • Excellent choice for woodland gardens, cottage gardens or wildflower gardens where it can form attractive colonies over time. It makes a good groundcover.
  • Easy to grow, disease and pest free
  • Cutting back stems promptly after flowering may encourage a possible rebloom and neat, young foliage.
  • Propagate by division of fleshy roots in spring. Propagate by root cuttings in early winter. Propagate by seed sown in pots in a cold frame in autumn or spring.
  • Ingestion may cause severe discomfort
