Cult. None of these plants are worth cultivating except in 
general collections. ‘The perennial species can be increased by 
dividing the plants at the root or by seeds. The seeds of the 
annual and biennial kinds only require to be sown in the open 
ground. They will all grow under any circumstances.

A very polymorphous plant; it is sometimes smooth, some- 
times hairy, from 3 inches in height to 2 feet, and the flowers are 
very variable in colour. Perhaps numerous species are con- 
fused under the head of varieties. The whole herb is acrid to 
the taste, and has a strong disagreeable smell when bruised. 
The seeds are very acrid, and blister when bruised and applied 
to the skin ; they are also reckoned sialagogue and aphrodisiacal.

This plant has been known in Britain since 1573. When in 
flower, in July, it has a strong peculiar smell, almost fetid. 
This plant is now neglected in Britain, but is still in use in 
several places on the continent, where the leaves and tender 
stalks are used as salad ingredients, and form an agreeable addi- 
tion to Mustard and Cress early in spring. The seeds should 
be sown in a warm border, early in February, and again in 
March and April, for successive crops. Thin the plants after 
they have produced the first rough leaves, to 3 or 4 inches 
apart, and keep them clear of weeds. If a supply is desired 
throughout the year, monthly sowings may be made. They will 
produce abundance of seed in August: for this purpose allow a
