Choose plants wisely for the front row

The plants at the visible edge along a walk, patio, or lawn, can make all the difference in its appearance. Low-growing plants in the front row accentuate the shape of the bed, soften harsh edges, and help draw attention to the taller plants behind. Low-growing boxwood, shaped as small globes, make a neat and intriguing edge along a stone walk. Low growing plants in the front row should be full, look good in a line, and not require too much care. If you view a garden bed from a distance, the height of edging plants can be relatively high—around 2 feet. In beds that are viewed up close, the border plants should be lower than 2 feet.
Annuals such as sweet alyssum make a wonderful white edging with its dense, tiny, fragrant white flowers. If cut back they will bloom all season. The perennial green and white variegated lilyturf (Liriope muscari) is another of my favorites for edging beds.
