Description
Diervilla sessilifolia 'Butterfly' | Southern bush honeysuckle
Southern bush honeysuckle 'Butterfly' is the named cultivar of Diervilla sessilifolia 'Butterfly', a deciduous shrub with an upright, bushy and spreading habit. It grows to approximately 150 cm tall, creating a full, lower planting presence rather than a tree-like crown or a climbing form. During the growing season, the shrub carries green to yellow-green leaves. Yellow flowers add seasonal interest from June to August, followed by red-purple autumn colour before the leaves fall in winter. This is a hardy and low-maintenance Bush honeysuckle for UK gardens, especially where partial shade is available. Its shape works well in a border, in group planting or at a woodland edge, where the spreading growth can add useful volume. The shrub is not an evergreen honeysuckle, and it should not be confused with climbing honeysuckle from the genus Lonicera. As a member of the diervilla genus, it offers a clear shrub habit with seasonal foliage and flowers. The cultivar name 'Butterfly' is kept as part of its plant name and identifies this particular form.
Key features of Southern bush honeysuckle (Diervilla sessilifolia 'Butterfly')
- Yellow flowers are a notable seasonal feature. They appear from June to August, bringing a warm colour to the summer border without changing the shrub’s compact, bushy character.
- The foliage is green to yellow-green during the growing season. In autumn, it changes to red-purple, giving the deciduous shrub another period of colour before it loses its leaves for winter.
- Southern bush honeysuckle 'Butterfly' grows in sun or partial shade, with partial shade being a key advantage. It suits UK gardens where a sheltered aspect and reliable seasonal interest are wanted.
- Choose humus-rich, well-drained and lightly moist soil. The soil should retain some moisture but must not become waterlogged, so good drainage and an open soil structure are important. The shrub is upright, bushy and spreading, remains low-maintenance and can produce suckers. It also fits naturally within yellow-flowering shrubs.
Uses of Southern bush honeysuckle 'Butterfly' in the garden
- Use this Southern bush honeysuckle in UK borders, group planting, formal planting areas and woodland-edge settings. Its lower, fuller shrub form adds planting volume without creating a tree-like crown.
- The plant is hardy to USDA zones 4 to 8. This gives a broad indication of its cold tolerance, although conditions can still vary between UK gardens and different microclimates.
- Its upright, bushy and spreading structure combines naturally with other shrubs, flowering shrubs, foliage plants and shade-tolerant or partial-shade border plants. Sucker-forming growth is worth considering when choosing its position within a planting scheme.
- The main ornamental value comes from several seasons of interest. Yellow summer flowers, green to yellow-green foliage and red-purple autumn colour work together with the full shrub silhouette.
Southern bush honeysuckle 'Butterfly' adds reliable seasonal structure and colour while remaining low-maintenance. It is a strong choice for a UK border or woodland-edge planting scheme, especially where partial shade is available.
