Buddleja lindleyana grows to < 3 m in height in the wild, its slender branches tetragonous in section, and slightly winged. The dark green leaves are opposite, ovate , 4 – 20 cm in length. The individual purple flowers are arguably among the most attractive of the genus , but occur in such small numbers intermittently along slender, terminal ...
Buddleja japonica is a deciduous shrub in the family Scrophulariaceae. [ 1 ] [ 2 ] It is native to Honshu and Shikoku , Japan , where it grows on mountain slopes amid scrub. [ 3 ] The shrub was named and described by Hemsley in 1889, and introduced to Western cultivation in 1896.
Buddleja macrostachya grows 1–6 m in height, flowering from March to September in the wild. The branchlets are quadrangular, and winged, stellate tomentose when young. The leaves are sessile or subsessile, narrowly to very narrowly elliptic, and hugely variable in size, ranging from 4–45 cm long by 1–15 cm wide, mostly stellate tomentose, the margins crenate-serrate, and the apex acuminate.
Buddleja (/ ˈ b ʌ d l i ə /; orth. var. Buddleia; also historically given as Buddlea) is a genus comprising over 140 [3] species of flowering plants endemic to Asia, Africa, and the Americas. The generic name bestowed by Linnaeus posthumously honoured the Reverend Adam Buddle (1662–1715), an English botanist and rector , at the suggestion ...
Buddleja nivea reaches 1–3 m high, and is chiefly distinguished by the dense white indumentum covering the branchlets, calyxes, and undersides of the leaves. The lanceolate leaves are of variable size, 6–22 cm long by 1.5–11 cm wide; they are acute or acuminate at the apex, rounded at the base, and very coarsely toothed except at the apex.
Buddleja tubiflora grows to < 2 m in height, with the typically lax habit creating a spread of < 3 m. The shrub is chiefly distinguished by its striking orange flowers, the corollas 25 mm long by 6 mm wide at the throat, borne in axillary clusters towards the ends of the branches.
