Hydrangeas are one of the most popular plants in America. They can be grown indoors or outside in the garden, allowing their blooms to be enjoyed at any time of the year. Florist-grown hydrangeas can provide double the enjoyment since their flowers can be enjoyed indoors first, and then be pruned back and transplanted outdoors for a second bloom later in the season.
The two most popular types of hydrangea are mop-head and lace cap. Mop-heads have large, rounded heads, while lace caps have a smaller cluster of flowers surrounded by a halo of larger flowers around their edge.
Most hydrangeas grown today come in shades of pink, blue or white. In many varieties, the color can be altered with the addition of lime or aluminum sulfate.
In the garden, hydrangeas do best in a morning sun, afternoon shade location and look great when planted under trees or other larger shrubs. Keep your plants watered regularly so the soil is moist but not wet. Most hydrangeas perform best when fed a couple of times during the growing season with an acid food.
