BUDDLEIA 



BUDDLEIA 



585 



BUDDLfilA (after Adam Buddie, an English bota- 

 nist). Syn., Buddlea. Loganiacese. Ornamental shrubs 

 or trees, chiefly grown for their handsome flowers pro- 

 fusely produced in showy panicles or globular heads. 



Woody plants or rarely herbs, more or less covered 

 with a stellate, glandular or scaly pubescence: Ivs. 

 opposite, short-petioled, entire or serrate: fls. in racemes, 

 panicles or clusters; corolla tubular or campanulate, 

 4-lobed; stamens included, 4: fr. a 2-celled caps, with 

 numerous minute seeds. About 70 species in tropical 

 and temperate regions of Amer., Asia and S. Afr., of 

 which only a small number of hardier species is cult. 



The buddleias are deciduous or sometimes half- 

 evergreen trees or shrubs with usually quadrangular 

 branches, narrow rather large leaves and small lilac, 

 violet, white or yellow flowers in showy panicles or 

 clusters. None of the species is hardy North, but some, 

 as B. japonica, B. Davidii, B. Lindleyana and B. inter- 

 media will live through the winter, if protected with dry 

 leaves around the base; even if the stems are killed 

 nearly to the ground, they will freely push forth young 

 shoots in spring, which usually flower the same year. 

 The handsomest in flower are B. Colvillei, B. Davidii, 

 B. asiatica, B. globosa and B. officinalis. 



They grow best in a rich, well-drained soil, in a sunny 

 position; they are rather coarse plants and need much 

 space. Propagation is readily effected by seeds sown in 

 spring in gentle bottom heat, by greenwood cuttings 

 under glass, or by hardwood cuttings taken off 

 in fall and kept during the winter in a frost- 

 proof room.

4. Davidii, Franch. (B. varidbilis, Hemsl.). Fig. 675. 

 Three to 8 ft.: Ivs. nearly sessile, ovate-lanceolate 

 or lanceolate, acuminate, coarsely serrate, whitish- 

 tomentose beneath, 4^10 in. long: fls. in dense, terminal,

 ties longer; corolla lilac, with orange-yellow mouth,

 cies with showy and fragrant fls. appearing in great pro- 

 fusion in late summer; several varieties differing from the 

 type which has rather lax panicles of lilac-purple fls. with 

 an orange eye not very marked, by larger and denser 

 panicles and brighter color. Var. Veitchiana, Rehd. (B. 

 varidbilis var. Veitchiana, Hort.). More robust, erect at

 clusters of bright mauve-colored fls. with a bright orange 

 eye; begins to bloom early in Aug. J.H.S. 27: 182. J.H.

 tomentose outside, glabrous within except at the 

 mouth. Aug., Sept. W. China. G.C. III. 38:275.
