Camellia x williamsii 'Blue Danube'
Description: There are many varieties of the popular evergreen Camellia each producing an abundance of showy flowers available in a wide range of colours, and all suitable for the border or woodland garden.
'Blue Danube' is produces large double blooms of rose-lavender, peony-form flowers in spring.
Climate/Position: Ideally partial shade in a sheltered site. Can tolerate full sun if soil conditions are good (rich in organic matter) but avoid position facing early morning sun as this will burn the flowers in the coldest winter/spring mornings. Reasonable tolerance of coastal conditions.
Height/Spread: 2x 3 metres
Soil Requirements: Neutral / acidic soil, rich in organic matter and moisture retentive. It is a good idea to place mulch such as leaf-mould or bark around plants to keep roots cool and promote water retention.
Pruning: Generally avoid pruning. Deadheading not required as these the flowers shatter and fall cleanly.
If pruning is required for shaping or rejuvenation the plant will respond well to this. Cut back after flowering in late Spring.
Partial shade avoiding early morning sun to ensure flowers are not damaged.
The williamsii hybrids originate from the cross of C. saluenensis x C. japonica produced by J C Williams in the early 1930s. With their smaller tougher leaves, they are remarkably hardy even in the most extreme British weather.
Williamsii hybrids produce an abundance of flowers, even in areas of low light and despite harsh conditions, and are more successful than C. japonica in the Northern areas of the UK.
