Centranthus – Common Valerian

Centranthus – the common Valerian, which is of particular value where the soil is chalky, and therefore the range of plants is limited. The easily-grown plants produce throughout the summer closely packed, sprayed heads of bloom on 2-ft stems. C. ruber is red and C. alba, white. Propagation is from cuttings or seed, although the latter have to be weeded out thoroughly so that inferior seedlings are not grown on.
