  Create a natural privacy fence that greens the environment with tall plants that fill in quickly. Plants absorb many toxins and help clean the air. Tall plants provide privacy and a sense of seclusion. Create a small, private sanctuary in your garden, or go all out and create a living border around your property. Choose plants that are fast growing and pair them with long-blooming perennials to create a riot of color in your garden.

Monarda

• Monarda, or bee balm, is a fast-spreading plant, which is not surprising given that it is a member of the mint family, according to the Washington State University Clark County Extension. The flowers bloom nonstop all summer and come in a wide range of colors including purple, pink and blue. Bees, butterflies and hummingbirds are drawn to this plant because of its high nectar content. Bee balm grows 2 to 3 feet tall, so plant it in front of a taller plant, such as bamboo, for maximum privacy.

Phlox

  Phlox is available as both an annual, which is a plant that grows, flowers, sets seed and dies in one growing season, and a perennial, which is a plant that comes back every year. Annual phlox are low-growing. Perennial phlox is tall and fills in an area quickly. Tall garden phlox reaches a height of 2 to 3 foot at maturity. Plant in full sun and make sure there is good air circulation around the plants to prevent disease such as powdery mildew, to which phlox is prone. Phlox grows in clumps, and the older varieties will self-seed in the garden if allowed to set seed at the end of the growing season, according to the University of Minnesota Extension.

Bamboo

  Bamboo can be invasive and is considered an aggressive plant that will quickly take over a landscape if not controlled, according to the Clemson University Cooperative Extension. Choose a clumping bamboo instead of a running bamboo. As the clump gets larger, remove any parts of the plant that are growing in an area where you don't want them. The easiest way to remove them is to dig the clumps early in the spring as soon as the bamboo starts to grow. Regular mowing around bamboo clumps is another way to control its spread. A third option is to grow bamboo in a container above ground, or sink a container into the ground leaving an inch or so of the edge of the pot above ground to prevent the plant from spreading underground.
