hydrangea

Shrubby hydrangeas brighten borders in mid to late summer with their showy, but delicate, long-lasting flowers in shades of pink, white or blue. Many have attractive autumn colour and leaf shape. Climbing hydrangeas flower in summer and are well suited for covering north and east-facing walls. Most popular is the fully hardy Hydrangea anomala subsp. petiolaris. Evergreen Hydrangea seemannii and Hydrangea serratifolia need shelter as they are prone to cold damage.

Native to Asia and the Americas

The flowers on a hydrangea shrub can change from blue to pink or from pink to blue from one season to the next depending on the acidity level of the soil. Adding organic materials such as coffee grounds and citrus peel will increase acidity and turn hydrangea flowers blue.

The white climbing hydrangea is a deciduous shrub with dark green ovate to rounded dark green leaves. The flowers are produced in clusters of white small blooms in the summer.

Propagation Notes

  • Plant Type: perenial Shrub or Climber

  • Propagation: Cuttings

  • Hardiness: Hardy

  • Flowering Season: Summer

Some are best pruned on an annual basis when the new leaf buds begin to appear. If not pruned regularly, the bush will become very “leggy”. Other species only flower on “old wood”. Thus, new wood resulting from pruning will not produce flowers until the following season.

The flowers of many hydrangea act as natural pH indicators, sporting blue flowers when the soil is acidic and pink ones when the soil is alkaline
