Buddleja Unique A dwarf, free-flowering, long-flowering butterfly bush, Buddleja alternifolia Unique is a fast-growing, deciduous shrub with a compact, mound-forming, weeping habit, suitable for quite small gardens. The lance-shaped leaves are silvery grey-green and rather furry. Spires of scented, clustered lilac flowers are borne in June and continue into October, flowering on new season’s wood; it has plenty of nectar for butterflies and other pollinators, but no pollen. It is sterile, so won’t seed about in your garden. Prune Buddleja Unique in March, cutting it hard to the base. Buddleja Unique also does well in a sunny patio pot.  Site: ShelteredSoil: Any fertile, well-drained soilPosition: Full sunSeason of interest: SummerHardiness: Very hardyHeight:  39” (1m) Spread: 28” (70cm) in 5-10 years Photo by Richard Loader, plant Bred by Peter Moore of Longstock Gardens.
