‘Roco Black Knight’ is a vibrant Hydrangea, that blooms from July until October. It generates an abundance of deep red flowers, that contrast wonderfully against its neat and compact growing habit of deep green leaflets. Perfect for growing in patio containers, cut flower and cottage themed landscapes, be sure to position in semi shade where it can develop in height and spread to around 120cm.
Growing Information
Hydrangea macrophylla prefers a sunny or semi shaded position, with shelter from cold, drying winds. Grow hydrangea plants in any rich fertile, moist soil. Improve the soil prior to planting by adding with plenty of well rotted manure or garden compost, ensuring that it is mixed in thoroughly and deeply. Alternatively plant hydrangea macrophylla in patio containers in soil based compost such as John Innes No. 3.
