Berberis x ottawensis 'Superba'
An exellent handsome largedeciduous shrub, that is vigorous and has prikey stems. With long arching branches if pruned properly. Leaves broadly oval, deep red purple, brighter red in autumn. Flowers are small and yellow berries and bright red berries.
This shrub is tough and hardy against frosts, liking a lightly acidic soil. If the pruning is done well with attention to detail then deciduous Berberis like others pruned in this group give the most back of all the shrubs. The new growth that comes after pruning from the base of the plant gives a vibrant and very attractive form. The stems form long uninterrupted growth from top to bottom, making lovely coloured arching stems that bloom incredibly at the start of Summer.
