Hydrangea White Knight- Obsidian Collection 200MM

Hydrangea ‘White Knight- Obsidian Collection’ – 200MM

(Not currently available to be ordered)

I am Hydrangea White Knight. My family originated from Northern hemisphere

Botanic Name: Hydrangea macrophylla ‘White Knight’

Bushy – Summer-long flowering

I am a stunning Hydrangea with prolific mops of white flowers on distinctive and unusual black stems. Being deciduous my bare black stems make a statement in the garden during winter.

I am happy in most soils but appreciate regular moisture and good drainage. I can cope with extremes of temperature but my leaves may burn exposed to hot winds. If grown indoors I will appreciate being put outside during winter to rejuvenate.

My compact habit and bushy form suits me to mass planting, low hedges and shrub borders. I am very happy in pots and containers and a great way to bring colour indoors, to balconies and paved areas.

Prune me back hard to a bud pair in early spring to encourage good form.
