Four species. L. intermedia is a stove evergreen shrub; and two are stove annuals, requiring the usual treatment of tender annuals. Cuttings or seed. Loam and peat. L. leonurus is a green-house evergreen shrub, requiring the following treatment: -

"Strike from cuttings in May; keep in a forty-eight pot during the winter; in the beginning of April put into a pot thirteen inches in diameter, and place in a forcing frame kept at a temperature varying from 75° to 50°; here remain for about seven weeks, when remove to the green-house.

"After the end of June, force as much as possible by keeping the house shut up during the day, so as to concentrate all the heat which can be obtained from the sun, but no fire lighted except during cold nights in September and October; 120° is not too great for it, provided it has plenty of water; never suffer the surface of the earth to become dry, and generally keep about an inch of water in the pan. The quantity required in hot weather, nearly three gallons daily." - Gard. Chron.
