Blue Butterfly Bush (Rotheca myricoides) is a fast-growing, evergreen, or semi-deciduous shrub, typically reaching 2–3m in height, but can grow up to 4m in height. It has glossy green foliage and striking, two-toned butterfly-shaped violet-purple flowers with long, curved, violet anthers. Flowering takes place from spring to summer/autumn. This is followed by small, round green fruits that ripen to dark purple/black and are attractive to birds.
Excellent for small gardens, mixed shrub borders, container gardening, and informal, low-screening hedges. It is considered a weak-stemmed shrub that can act as a small tree if not pruned, but then the plant will need support due to its sprawling nature. It responds very well to regular pruning to encourage a bushy, dense, and flowering form. It thrives in hot, humid climates. In areas with extremely hot summers, it prefers some partial shade.
Common names: Blue Butterfly Bush, Blue Cat’s Whiskers, Blue Glory Bower, Bloutontelhout, Umbozwa, Blue Oxford/Cambridge Bush.
