Description
Cotinus coggygria 'Royal Purple' Half-standard 90 cm C7,5 | Smoke bush
The half-standard Smoke bush Cotinus coggygria 'Royal Purple' is supplied in a raised, half-standard form that gives it a clear and ornamental silhouette. Its raised trunk supports an elevated crown, so the plant has a more defined outline than a shrub-form Smoke bush. The upright, bushy growth habit adds structure while keeping the crown visually lifted above ground level. The broad deciduous leaves emerge in dark red to purple tones, with red-orange shades adding further seasonal interest. Attractive autumn colour extends the display beyond the flowering period. From May to July, the plant produces distinctive plume-like flowering structures in yellow-green and pink. These airy plumes add texture and contrast to the dark foliage. At maturity, this Smoke bush reaches approximately 300 cm in height. It is fruit-bearing, although the fruits are not a feature for human use. Relatively low-maintenance, it suits gardeners looking for a strong ornamental feature for a UK garden, including gardens with mild, often wet conditions where good drainage can be provided. As a member of the cotinus genus, it brings the familiar ornamental character of a Smoke bush together with the added structure of a half-standard plant.
Key features of Smoke bush (Cotinus coggygria 'Royal Purple')
- Distinctive flowering: Yellow-green and pink flowers appear from May to July. They form ornamental, plume-like structures that give this Smoke bush a soft, airy look above the darker foliage.
- Dark seasonal foliage: The deciduous broad leaves are dark red to purple, with red-orange tones during the growing season. Attractive autumn colour adds another period of interest before the leaves fall.
- Light and position: Plant in full sun or partial shade. In partial shade, the foliage colour is likely to appear greener. The raised trunk and elevated crown are especially effective where the plant can be viewed as a clear feature.
- Soil and drainage: Choose well-drained, dry soil that is neutral to slightly alkaline and preferably calcareous. Avoid persistently wet ground, as prolonged waterlogging is unsuitable. Good drainage is important in UK gardens, particularly through wet winters.
- Growth and form: The plant grows upright and bushy and reaches approximately 300 cm at maturity. As a half-standard Smoke bush, it has a raised trunk and elevated crown, creating a clearly defined silhouette with strong structural presence. It is a suitable choice among flowering shrubs.
Uses of a half-standard Smoke bush in the garden
- Specimen plant: Use this half-standard Smoke bush as an individual feature where its elevated crown can be seen clearly. The raised trunk gives the plant height and makes the silhouette more noticeable than that of an ordinary shrub form.
- Border or group planting: It can provide structure in a border or form part of a group planting. The dark red-purple foliage works well beside plants with contrasting foliage, flowering perennials or other structural garden plants.
- Container planting: The half-standard shape is also suitable for a pot where an upright Smoke bush is wanted. Its raised crown gives a container display a clear vertical element while keeping the lower part of the plant visually open.
- Hardiness: The supplied hardiness range is approximately -28.9°C to -12.2°C, corresponding to USDA zone 5. Local exposure and garden conditions still matter, especially in open or wet positions.
- Seasonal interest: Dark foliage, yellow-green and pink plume-like flowers, and autumn colour create interest over several seasons. The elevated crown helps show these features clearly and gives the plant a defined focal point.
This half-standard Smoke bush is a distinctive, relatively low-maintenance choice for adding foliage colour, seasonal interest and clear structure to a UK garden. Its raised crown provides height and a strong focal point while taking up less visual space at ground level than a broad shrub form.
