Until a few years ago this genus of Loganiaceae was rarely represented in gardens by more than one species, that being Buddleia globosa. Now there are several to select from, and all are showy.

They thrive in loamy soil, and are readily increased by means of cuttings or seeds. Two species, Buddleia intermedia and Buddleia Japonica, are at their best when about four or five years old, and it is advisable to destroy them and begin again with seedling plants (or cuttings of Buddleia intermedia) as soon as they begin to deteriorate. The best for general cultivation are:

Buddleia globosa, the Globe-flowered Buddleia, from Chili and Peru in 1774. This forms a bush 10 to 12 feet in height, with lanceolate, sub-evergreen leaves and small globose heads of golden blossoms, which are borne very freely in May or june.

Buddleia Japonica is a deciduous shrub 3 feet high, which bears long terminal racemes of purplish flowers in July and August.

Buddleia paniculata is found in China; it grows 6 or 8 feet high and has small, crisped, greyish leaves, and lilac flowers borne in May and June.

Buddleia variabilis. - This is a very showy Chinese plant, growing 8 or 9 feet high, bearing lanceolate leaves 6 to 9 inches in length, and long racemes of deep lilac flowers. It should be given generous treatment, and thrives best if cut back to within a few buds of the old wood annually. A variety known as Buddleia v. Veitchiana is far in advance of the type, the inflorescences being from 12 to 2 feet. long, the whole end of the branch becoming one large panicle of bloom.

Buddleia Colvillei will only grow in the milder parts of the country. It is the most beautiful of all, the blossoms being large and red like a small Pentstemon, and borne in long racemes. It is from Sikkim.
