Berberis × hortensis

Description

The hybrids show some variation, but are generally intermediate in most characteristics between the two parents. The following description is of the clone 'Charity'.

These are medium to large shrubs, reaching 4 m (13 ft) in height. The plants have an upright form, becoming bare at the base. There are between 7 and 11 pairs of leaflets, plus a terminal leaflet. The flowers are in somewhat spreading racemes, often as long as in Berberis japonica. There is some scent to the flowers, but it is not as strong as in B. japonica. Flowering goes on throughout the winter.

Different clones may resemble one or the other parent more closely. It is possible that other species of Berberis have contributed to the stock ascribed to this hybrid. Berberis bealei is considered particularly likely to be one of these as it is often confused with Berberisa japonica. Many clones have an upright architectural form derived from M. oiwakensis subsp. lomariifolia, though some resemble the B. japonica parent rather more.

Plants provide viable seed, and second generation hybrids have been raised.

The plants are especially valued in the garden because of their ornamental leaves, and because they flower through the winter.
