OriginUniversity of Arkansas, United States

Buddleja 'Asian Moon' is a sterile hybrid cultivar raised in 2001 by researchers at the University of Arkansas by crossing the tetraploid davidii cultivar (female parent) with the diploid B. asiatica Lour. to create a seed-sterile triploid.[1]

Description[]

'Asian Moon' produces a symmetrical round shrub. The plant grows to heights of 3.0 ft (0.9 m) to 7.0 ft (2.1 m) and widths of 3.0 ft (0.9 m) to 5.0 ft (1.5 m). The plant's inflorescence is an elongated terminal panicle that contains multiple fragrant light purple tubular flowers with orange throats whose hues depend upon the ambient temperature. The inflorescences are smaller than those that Buddleja davidii cultivars produce. The flower's corolla averages 9.1 cm (3.6 in) in length and 8.5 cm (3.3 in) in width. The plant's leaves are elliptical or lanceolate, have serrated edges and are dark green above and grey-green below.[1][2][3]

The original plant's flowering began in late May or early June in Fayetteville, Arkansas.[1] Flowering lasts until frost.[3]

The plant should be coppiced or cut to the ground in late winter, pruned in the spring to keep it fresh and cut back by half in late July to encourage heavy reblooming.[4] It can be used in mass for summer bloom and to attract butterflies, can be treated as a herbaceous perennial to give height in a mixed border or can be under-planted with low perennials.[4]

The original plant produced only vestigial fruit, with no viable seed.[1] Because the cultivar is non-invasive, the governments of the northwestern U.S. states of Oregon and Washington have approved it for sale within their jurisdictions, unlike their bans on B. davidii.[5]

Cultivation[]

The Monrovia Nursery Company in Azusa, California, the Greenleaf Nursery Company and others grow and market 'Asian Moon' in the United States.[3][4][6]

Hardiness: USDA zones 6–10.[3]
