Planting purple flowers in your garden can add rich thematic colors. Many gardeners combine their purple flowers with different shades of purple or other hues to come up with new garden designs. Most of these purple flowers come with thick green leafy foliage as well that provide color throughout the season.
Most purple flowers can be categorized according to perennial and annual flowers.
Perennial flowers are small flowers that grow and bloom over the seasons of spring and summer and then die back during autumn and winter although the roots survive winter season. These flowers are reborn again during spring to start anew and then the cycle repeats itself.
These herbaceous perennials live for more than two years and are some of the easiest to grow. Their roots remain firmly in the ground and are more far-ranging. Once established, they need only minimal maintenance in the form of watering and fertilizing. Perennial flowers are great garden spreads and add rich color to your garden.
Annual flowers, on the other hand, are so-called because they survive only one growing season. Most annual flowers need seeds to grow and require nurturing throughout the season. Garden owners would have to fertilize and water them regularly until the time comes for the flowers to die. By the start of a new growing season, the cycle repeats itself.
Apparently, most gardeners would choose purple perennial flowers for their garden for practical purposes. Whether you choose a purple perennial or annual flower for your garden, make sure that you know how much water the plant needs.
Some would require only minimum amount of water while others need to be watered thoroughly and regularly. Most of these flowers also love full sun but can also appreciate having some light shade during summer afternoons and some shade protection from the wind as well.
