Hydrangea macrophylla Nikko Blue - Hydrangea - Plant in 12 cm Pot

Hydrangea macrophylla sub group Hortenisa (mopheads). Perhaps one of the best known garden plants. Originally from Japan, these robust and reliable plants produce a truly amazing display in summer and autumn. Hydrangea macrophylla Nikko Blue is one of the most popular Hydrangeas and for good reason. A compact variety with large heads densely packed with rich blue florets (in acid soils) and it is very floriferous, producing new flower stems throughout the summer. Large, attractive, serrated, mid green leaves contrast superbly against the masses of large mophead flowers. Easy to grow in most moist soils, except chalky. To produce blue flowers the soils must be acidic. Alkaline soils will produce pink shades. Prefers some shade from strong summer sun. Will grow in full sun as long as the soil stays moist. Can be grown in a pot or container. Use a good quality John Innes compost as this plant will be there a long time and peaty types of compost eventually degrade, become too packed and choke the roots. Ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmoscote pro 8-9 month applied in the early spring. One application gives all the nutrients the plant requires for the whole year. John Innes is a soils based compost. After flowering prune back to close to the old wood.
