Description

Buddleja myriantha is deciduous shrub growing 1 – 3 m in height, with subquadrangular, glabrescent branchlets bearing opposite leaves, 5 – 20 cm long by 0.9 – 6 cm wide, narrowly elliptic, acuminate at the apex, cuneate or decurrent at the base, the margins serrate or entire. The often fragrant inflorescences are slender, thyrsoid, almost cylindrical, 6 – 22 cm long by 1.2 – 3 cm wide. The colour of the flowers ranges from purple through violet, to white. The corollas are 5 – 7 mm long.[1] 2n = 76.[3]

Buddleja myriantha most closely resembles Buddleja albiflora, and it can be distinguished by its four-angled stems and tomentose exterior to the corolla tube [1].

Cultivation

Buddleja myriantha is grown in the UK. A specimen is grown at the Royal Botanic Gardens Edinburgh [4].
