Red valerian: Centranthus ruber

The crimson flowerheads of Jupiter's beard are held above smooth, leathery leaves and make this many-branched perennial well-suited for planting in a shrub border or along a wall or stony bank. This carefree, drought-resistant plant is also a strong self-sower but may falter in the heat and humidity of the South.

did you know?

The name is from the Greek "spur," and "flowers," which refers to the spurred base of red valerian's flower heads.

general maintenance:

Deadhead regularly during the season to encourage rebloom. Cut back foliage in late fall or early spring before new growth emerges.

pests/diseases:

Jupiter's beard is relatively carefree.

how to sow/plant:

Start with new plants, divisions, or seed. Choose a sunny site with well-drained, preferably alkaline, soil. Direct sow after danger of frost has passed and thin to 2?3 feet apart. Or set out young plants or divisions at a distance equal to their mature spread. Water after planting.

water and fertilize:

Monitor soil moisture all season. Although Jupiter's beard tolerates poor soil, a balanced fertilizer may be used at the beginning of the season, following label directions.

garden hint:

Primarily a spring bloomer, Jupiter's beard may flower all summer with diligent and careful deadheading (cut off spent flowers at the leaf axil just below the bloom, being careful not to remove developing flower buds).
