Cult. 'The greater part of the species of Dracocéphalum, 
being showy when in blossom, are favourites with all lovers of 
flowers. They are all hardy, and will grow in any common 
garden soil; they are, therefore, well adapted for decorating 
flower borders and rockwork. The perennial species are rea- 
dily inereased by divisions of the root and top in spring. The 
seeds of annual kinds only require to be sown in the open 
ground in spring. The two shrubby species, D. fruticulosum 
and D. integrifólium, and all the species belonging to sect. $ 
Keimodracon, will require protection in severe weather mM 
winter; these are all readily propagated by cuttings, under à 
hand-glass.
