Centranthus. [Valerianaceae.] Ornamental hardy 

 perennials or annuals. The perennials are best raised from 

 seeds ; for, having but few thick woody roots, they do not 

 divide well, like many other hardy perennials. The seeds 

 should be sown in May on a bed of light, not over rich, 

 soil, from which they may be transplanted to a nursery-bed 

 as soon as large enough to handle, and will be fit to be 

 transplanted in the autumn into the positions in which they 

 are required to bloom the following year. The plants grow 

 readily in common light garden soil. The annuals require 

 to be sown in the open border in March or April, and like 

 a rather moist soil.
