Sweet Peas 'Garden Orchids'
This old heirloom vine, also called everlasting pea, was grown by Thomas Jefferson. The vigorous vines can grow 9 to 12 feet tall, bearing heavy clusters of dainty 1 1/2 inch blossoms in white, blushed pink and carmine rose. Drought-tolerant perennial sweet peas make a handsome flowering screen that comes back reliably every season. Although perennial sweet pea blossoms are not as fragrant as their scented annual cousins, their pearly flower clusters make lovely bouquets that seem to arrange themselves.
