Buddleja Purple Haze (LO & BEHOLD series; selling name Purple Chip in Europe) is a sterile hybrid cultivar derived from a 2004 crossing of 'Miss Ruby' and clone no. NC2003-4: 'Honeycomb' × (Nanho Purple™ × lindleyana) in the plant breeding program of Dennis J. Werner and Layne K. Snelling of North Carolina State University (NCSU) at the JC Raulston Arboretum.[1][2] Werner and Snelling selected ‘Purple Haze’ in field trials in 2005 at the Sandhills Research Station in Jackson Springs, North Carolina.[3][4] NCSU's North Carolina Agriculture Research Service released the cultivar to commerce in 2010.[3] NCSU received United States plant patent number USPP24514P2 for the cultivar on June 3, 2014.[2]

Description[]

Buddleja Purple Haze produces a dense compact mound whose height is 2.0 ft (61.0 cm) to 3.0 ft (91.4 cm), whose width is 3.0 ft (91.4 cm) to 4.0 ft (121.9 cm) and whose branches extend to the ground. The plant's inflorescences contain loose arching pendulous terminal panicles whose lengths average 19.6 cm (7.7 in). Each panicle holds an average of 85 fragrant purple flowers with orange centers whose lengths average 15 mm (0.6 in) and whose widths average 5.4 mm (0.2 in) wide at the apex, reflecting the cultivar's lindleyana heritage. The flowers are considerably larger than are those typical for Buddleja davidii. The plant's elliptical leaves are 10.5 cm (4.1 in) long and 2.6 cm (1.0 in) wide, green above and grey-green below when mature.[1][2][3]

Werner and Snelling's publication on the cultivar stated that, because of its compact growth habit and pendulous panicles, ‘Purple Haze’ is appropriate for use in the front of mixed plantings or for mass plantings. Their publication also stated that, like most Buddleja, 'Purple Haze' attracts butterflies in abundance.[3]

Flowering begins in early to mid-June in Raleigh, North Carolina, and continues throughout the growing season until the first fall freeze event interrupts it.[3] The plant can be treated as a perennial and cut to the ground in late winter or early spring. After the threat of frost has passed, the plant will grow back quickly.[1]

The flower's anthers are normal and produce abundant pollen. The plant is female-sterile. Five years of field observation of ‘Purple Haze’ in mixed plantings with numerous pollenizer cultivars produced no evidence of fruit and seed production.[3] Because the cultivar is non-invasive, the governments of Oregon and Washington have approved it for sale in their states, unlike their bans on B. davidii.[1][5]

Cultivation[]

Proven Winners LLC of DeKalb, Illinois, markets 'Purple Haze' in the United States.[6] The plant has been introduced to the National Council for the Conservation of Plants and Gardens (NCCPG)'s National Plant Collection at the Longstock Park Nursery near Stockbridge, Hampshire, England.[7] England's Thompson and Morgan markets the plant as 'Purple Chip'.[8]

Hardiness: USDA zones 5–8.[1]
