Hydrangea macrophylla, perhaps one of the best known garden plants. Originally from Japan these robust and reliable plants produce a truly stunning display in summer and autumn. Hydrangea macrophylla Blaumeise is one of the best hydrangeas from the Swiss bred Teller and is often sold under the invalid name of 'Teller Blue'. This Hydrangea almost glows, with large flat flowers composed of very wide deep blue to indigo sterile florets surrounding tiny fertile flowers even deeper in hue in acidic soil. The colour holds well through the summer. Accentuating the showy blooms is the bold shiny bright green leaves with a strongly toothed edge. If you have alkaline soil, regular watering with a Hydrangea bluing agent will help ensure bluer flowers. Very easy to grow, it can be grown in the garden or in a pot or container. In containers 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. A vigorous grower that will need pruning. After flowering prune back to close to the old wood. If the plant becomes too large a more drastic pruning can be undertaken!
