Sorbus 'Joseph Rock' is a lovely upright small tree with toothed bright green leaves, turning fiery shades of orange, red and purple in autumn. Dense clusters of frothy white flowers in late spring, which are highly attractive to pollinators, are followed by pale yellow orange berries in later summer, which tend to persist well into winter, before becoming a tasty treat for birds. Excellent for small gardens 'Joseph Rock' may grow 6m tall by 4m wide in 20 years. Requires moist but well drained conditions in full sun or semi shade.
