Popular shrubs called Hydrangeas have vibrant flowers that bloom from the summer into the fall. Compared to most other plants, they blossom for significantly longer periods of time - often months as opposed to weeks. They often form flowerheads (corymbs or panicles) at the stem ends. Usually, flowerheads have two different kinds of flowers: little, unattractive fertile blooms in the center or interior, and large, sterile, spectacular flowers with brightly colored sepals (tepals). Even after they have gone, the blossoms frequently keep their beauty, giving the garden interest even in the dead of winter. They make wonderful cut flowers as well. As a result, planting a garden of Hydrangeas is one of the best choices to create a vivid and gorgeous space.
