Hydrangea shrubs produce prominent and colourful flowers. The part of the plant commonly referred to as the flower is actually a cluster of bracts, which are leaflike structures that often resemble flower petals.
The hydrangea shrub has the potential for a long lifespan, but this depends on the quality of care it receives. According to the book "Hydrangeas: A Gardener's Guide," hydrangeas can survive for more than 50 years under the right conditions.
Although hydrangeas do not require specialised care, they do have certain requirements. They need full sun or partial shade and thrive in a moist, slightly acidic soil. Avoid planting hydrangeas on a dry, windy site. This causes their leaves to lose moisture and wilt.
Grow hardy varieties of hydrangeas in the northern part of the United States to lessen the danger of losing a plant to frost, advises the University of Rhode Island. Hills of snow hydrangea and climbing hydrangea are two top recommendations.
