Buddleja Lo & Behold 'Ice Chip'

Buddleja 'Ice Chip' (LO & BEHOLD series; selling name White Chip in Europe) is a sterile hybrid cultivar derived from a 2005 crossing of 'Blue Chip' and the breeding parent NC2002-12 ('White Ball' × Nanho Purple) 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 ‘Ice Chip’ in field trials in 2006 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 2011.[3] NCSU received United States plant patent number USPP24015P3 for the cultivar on April 5, 2016.[2]

Description
Buddleja 'Ice Chip' panicle

Buddleja 'Ice Chip' is possibly the world's first groundcover buddleja, growing outwards to more than double its diminutive height of 0.5 m (1.6 ft). The shrub has a dense, rounded structure owing to the development of numerous lateral branches. The fragrant inflorescences are small terminal panicles, 8 cm (3.1 in) in length holding up to 130 white flowers, greyish-yellow within the corolla tube. The mature leaves are elliptic, 7.5 cm (3.0 in) long by 2.5 cm (1.0 in) wide, green above and grey-green below.[3]

Werner and Snelling's publication stated that, because of its compact and spreading growth habit, ‘Ice Chip’ is appropriate for use in the front of mixed plantings and as a groundcover in mass plantings. Their publication also stated that, like most Buddleja, 'Ice Chip' attracts butterflies in abundance.[3]

'Ice Chip' may die back to the ground in colder zones and resume growth from the crown the following spring. In regions where above-ground shoots survive over winter, pruning to the ground in late winter when new leaves appear at the base will produce more vigorous growth in the spring, give the plant a better shape, and produce more flowers.[1]

The flowers' anthers are either absent or malformed and are thus incapable of pollination. The flowers are also female-sterile and therefore produce no seeds.[3] Because the cultivar is non-invasive, the governments of Oregon and Washington have approved it for sale in their states, unlike their bans of Buddleja davidii.[1][5]

Cultivation

Proven Winners LLC of DeKalb, Illinois, markets 'Ice Chip' 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 'White Chip'.[8]

Hardiness: USDA zones 5–9.[1]
