Stunning Hydrangea Garden Plants
Hydrangea garden plants are relatively easy to grow. Just give them lots of water and sufficient sunshine, and you’ll have a healthy happy bush that blooms lovely heads of dainty florets. Hydrangea garden plants are large flowering bushes native to the Northern Hemisphere. There are around 23 species in the Hydrangea genus, with around five in common domestic cultivation. The most common species used in gardens is Hydrangea macrophylla, also called French or Bigleaf Hydrangea. When most people think of hydrangeas, they visualize cultivars of this abundant species. While most hydrangea garden plants are flowering shrubs or bushes, some are actually climbing species. In all cases, hydrangeas have large, simple leaves and big clusters of flowers which may be white, pink, purple, red, or blue, depending on cultivar and soil conditions. Hydrangeas are easy to prune and shape, and in rich soil, they thrive, developing vigorous growth habits and quickly dominating their corner of the garden.
The flower colors of H. macrophylla is variable because the garden plants respond to the mineral and pH balance of the soil. Acidic soils produce blue flowers, while basic soils develop white flowers. Soil with a neutral pH will produce pink to purple flowers, and the flower color can be further influenced by the minerals in the soil, the amount of fertilizer the plant gets, and how healthy it is. Healthy plants tend to have very rich color saturation in their flowers, while unhealthy plants develop pallid, faded flowers.
