Hardy deciduous shrubs with sweet-scented leaves and inconspicuous lilac-colored flowers. In the Eastern States and in Europe these shrubs are grown in the greenhouse where they are general favorites for cutting. In California they grow to the height of ten feet or more, having trunks six inches (and even greater) in diameter. They flourish in any good garden soil and stand a reasonable amount of exposure.

Propagation of the Aloysia is effected by cuttings of the young wood placed in sandy soil in a cool frame in early Summer. They should be shaded, during sunshine, for a period of two weeks and should be potted singly in two-inch pots as soon as the cuttings are rooted.
