The Hydrangea Plant

The Hydrangea plant can be found in many old fashioned gardens. Their large shapes dotted with large clusters of blue or pink flowers often elicit memories of your mom's or grandmother's house.

There are many hydrangea varieties used in the garden. Hydrangea arborescens is also known as the Hills-of-Snow hydrangea.

Hydrangea paniculata is the most frequently planted variety. Also known a Pee Gee hydrangea, it starts with white flowers and then fades to pink.

Hydrangea macrophylla is the one you remember from your grandmother's garden. Large globes of flower clusters will appear blue in acidic soil, pink in alkaline soil and white in neutral soil.

Hydrangea quercifolia is known for its beautiful foliage that resembles oak leaves. It provides excellent fall color, nice flowers and attractive bark for winter.

Hydrangea anomala petiolaris is a climbing hydrangea. This woody vine uses aerial roots to attach to wood, brick or masonry and has nice flowers in the middle of summer.

Landscaping With Hydrangeas

The hydrangea plant is known for its rounded shape and large leaves with serrated edges. The leaves are dark green. It can reach 3 to 6 feet tall and about the same distance from side to side.

Hydrangeas are wonderful as foundation plantings or in shrubby borders. In warmer areas, they can be used as flowering hedges. The dark foliage makes a good backdrop for white and pastel flowers. When you let it grow to its full potential, it makes a magnificent specimen plant.

Care of Hydrangeas

To adjust the color of your hydrangea macrophylla, add aluminum sulfate until the pH is between 5.0 and 5.5 for blue flowers. For pink flowers, add limestone when you plant the shrub to make the soil between 6.5 and 7.0.

Always test your soil before adding anything. If you continually change the pH, you can make it difficult for the plant to take up nutrients. Most varieties have large ball-shaped clusters of simple flowers. Lacecap varieties have flat clusters of tiny inflorescences surrounded by large sterile blossoms.

These deciduous plants provide a lot of visual interest in the summer. The shrub blooms on the previous year's growth, so a mild winter is necessary for good flowering. Hard winters will kill the flower buds. Native to Japan and Korea, the hydrangea plant can easily naturalize in similar climates. They like rich, loose soil that is moist but well drained. It can take full sun in cooler climates.

In hot areas, the plant prefers part shade. Hot sun will cause the leaves to wilt even if it has just been watered.

Prune old flowers as soon as they fade since new buds will form soon after.

It is hardy from USDA zones 6 through 10.

Hydrangeas are easily propagated by cuttings. Minimal pruning is best for the most flower production. Hydrangea flowers can be air dried for everlasting bouquets. They can be left natural or spray painted. Natural dried flowers need to be sprayed with hair spray to stiffen the blossoms and preserve them.

Hydrangea plants are often purchased as holiday gifts for Easter or Mother's Day. They are brought into full bloom before their normal time to look perfect.

The important thing to remember if you get one of these as a gift is that they dry out quickly, especially in the house. Keep the soil moist at all times. It needs direct sunlight as well. Once the flowers fade, clip them off and treat the plant like any other house plant. Once there is no danger of frost, it can be placed outside in the garden in a sheltered area.

It is important to shelter the plant since it was grown in a greenhouse and needs time to adjust. If you live in a cold area, it may not produce flowers. You can help the situation by sheltering the plant and even covering it with burlap if needed.

In mid-July, prune your hothouse hydrangea about 5 inches from the ground. The shrub will produce short branches that end in a dormant flower bud.

In the winter, before the temperature reaches 25 degrees Fahrenheit, surround the plant with a screen. Fill this with insulation such as peat moss or vermiculite. Add more if it settles as time passes. Remove this when the crocuses begin to bloom, but cover it at night if it gets cold. This may help the buds to survive.

"A picture is worth a thousand words" This quote rings so true when it comes to landscaping. We see all those landscaping pictures in magazines and books. But I have a feeling that the vistors to backyard-landscape-ideas.com, have some great backyard pictures themselves.
