Buddleja 'Blue Chip Jr' (Lo & Behold series) is a dwarf hybrid cultivar derived from a 2008 crossing of 'Blue Chip' and clone NC2006-18 in the plant breeding program of Dennis Werner of North Carolina State University (NCSU) at the JC Raulston Arboretum.[1][2] Werner selected the cultivar in field trials in 2009 at the Sandhills Research Station in Jackson Springs, North Carolina.[2][3] NCSU's North Carolina Agriculture Research Service released the cultivar to commerce in 2013.[4] NCSU received United States plant patent number USPP26581P3 for the cultivar on April 5, 2016.[2]

Description[]

The cultivar is an alternative to 'Blue Chip' with many of the same characteristics. Some consider it to be an improved variety because of its more compact and symmetrical shape, consistent purple-violet color, silver-green foliage, earlier flowering, and stronger stems.[1] The plant grows to a height of 1.5 ft (0.5 m) to 2.5 ft (0.8 m) and a width of 2.0 ft (0.6 m) to 2.5 ft (0.8 m).[1]

The plant's inflorescence is a panicle.[2] The sizes of the panicle's fragrant flowers are less than 1.0 in (2.5 cm).[1] Flowering usually begins in late May to early June in Jackson Springs, North Carolina, and continues throughout the growing season until the first freeze event in October or November.[2] The plant is the earliest to bloom of all of the Lo & Behold series.[1] It attracts butterflies and other pollinators seeking nectar.[1]

‘Blue Chip Jr’ lacks male flower parts (anthers), resulting in male (pollen) sterility. The plant's female structures are essentially sterile, resulting in a lack of seed formation.[2] Deadheading encourages additional blooms but is not otherwise necessary. The plants produce few seeds and infrequently sucker in the garden. Because the cultivar is non-invasive, the governments of Oregon and Washington have approved it for sale in their states, unlike the banned Buddleja davidii.[1][5]

Cultivation[]

Proven Winners North America LLC of DeKalb, Illinois markets 'Blue Chip Jr.' within 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]

Hardiness: USDA zones 5–9.[1]
