Buddleja fallowiana
Template:Short description Template:Speciesbox
Buddleja fallowiana is a species of flowering plant in the figwort family Scrophulariaceae.[1] It is endemic to the Yunnan province of western China, where it grows in open woodland, along forest edges and watercourses.[2] The plant was collected in China by the Scottish botanist George Forrest in 1906, and named in 1917 by Balfour and Smith for George Fallow, a gardener at the Royal Botanic Garden Edinburgh. Fallow had died in Egypt in 1915 from wounds sustained fighting in the Gallipoli Campaign.[3]
Description
Buddleja fallowiana is a deciduous shrub typically growing to a height of Script error: No such module "convert".. Of loose habit, the plant has young shoots clothed with a dense white felt. The ovate to narrowly elliptic leaves are Template:Cvt long by Template:Cvt wide, acuminate or acute at the apex; the upper and lower surfaces densely tomentose, bestowing a silvery grey sheen. The inflorescences are slender, thyrsoid, sometimes interrupted, with panicles at the ends of the current year's shoots. The flowers are Template:Cvt long by Template:Cvt wide, comprising fragrant lavender blue flowers with orange throats, the corollas 2 – 3.5 mm wide by 9 – 14 mm long with erect lobes. The flowers bloom in late summer and autumn.[4]
Growth is significantly slower than that of B. davidii; Bean considered the species more closely allied to B. nivea,[2] although its chromosome number, 2n = 76 (tetraploid), places it alongside the similarly tetraploid B. davidii.[5]
Cultivation
Somewhat tender, B. fallowiana is best grown against a wall. However, if cut to the ground by frost, it will grow again from the base. Hardiness: USDA zones 8–9.[6]
Varieties
The variety was considered horticulturally superior to B. fallowiana by Bean, who thought it one of the most attractive of all Buddlejas;[2] it was accorded the Royal Horticultural Society's Award of Garden Merit in 1993.[7] However, its varietal status was challenged by Leeuwenberg, who considered its colouration insufficient to justify it as a variety, and sank it as simply B. fallowiana.[4]
Hybrid cultivars
A number of hybrid cultivars have been raised, invariably through a crossing of the species with Buddleja davidii:
