Cult. The common horse-radish should be planted in Febru- 
ary or October in the way recommended under that species, in a 
deep rich soil. The smaller perennial sorts do best in pots, 
placed among other alpine plants, but the larger ones should be 
planted in a shady, rather moist situation, in the open border. 
The biennial and annual kinds only require to be sown in the 
open border, the greater part of them grow best in a damp 
situation, the seeds should be sown directly after they have ri- 
pened, or they may be allowed to sow themselves. They are 
all easily increased by seeds except Cochledria armordcia and 
macrocarpa, which do best by slips from the root, and some 
others of the perennial species which do not seed freely may be 
increased by dividing the plants at the root. `
