Keep foliage color in mind when you plan your perennial border. Plants with colorful foliage such as artemisia will keep the garden looking good while flowering plants go in and out of bloom. Artemisia has beautiful silver-gray foliage that won’t fade in the hot sun. This hardy perennial is also drought and insect resistant, and the branches make a wonderful addition to indoor flower arrangements. Height varies by variety and can range from 3 feet tall to just 5 inches. Grows in Zones 4-9.
Shade-tolerant white impatiens border. Plant 12 inches apart (measured center to center). The more tightly they are spaced, the taller they will grow. For a deeper, denser border, plant one row offset in front of another, with 10.5 inches between rows. New Guinea Impatiens have better foliage and will tolerate more sun, but are still not full sun plants. If you can provide a moist soil with some relief from the sun during the hottest hours, they are an excellent border choice.
Rhoeo Discolour - Moses in the Cradle is an interesting, drought-tolerant plant with small sword-like leaves which form a rosette of white, pale pink, and green leaves with purple undersides. It adds a nice textural accent to the garden in partial to full-sun settings.The better the sun exposure the better the color. It grows 12 to 24 inches tall and wide. Use as a border plant or ground cover, or as a container plant. Landscape Garden Recommend
