We must not forget the Perennial Sweet Pea. This is a climber whose shoots die down annually, leaving the trellis clear for painting and other maintenance work and allowing its pattern to show and give distinction to its surroundings during the dreary days of winter. Pink, red, or white flowers are produced over a long season during the summer, the vine needing a minimum of care. They may be used as cut flowers, although they do not have the scent of their little annual sisters.

. . . annual vines may be the best choice
Most trellis builders will agree that the annual vine is the best choice. There is a wide range to select from: lacy, finely-cut leaves, bright green or dark green, heart-shaped or with multiples of various shapes on one stem-and in addition many colors and shapes of flowers from which to choose. Annual vines, of course, die down each autumn like the Perennial Sweet Pea, permitting the growth to be removed and the trellis laid bare for winter maintenance and for displaying its beauty of design. Annuals grow from seeds and in most cases the growth is very rapid. In northerly regions they may be started indoors; then taken from their pots and placed in their summer location when the weather is sufficiently warm.

Possibly the favorite annual vine in America is the Heavenly Blue Morning Glory, but Pearly Gates (white) and Blue Star (blue with a white star in the throat) are also beautiful. Scarlett O'Hara or the new wine red Darling varieties may be used if red is desired.

Moonflower vines are nocturnal bloomers, and then grow quickly to cover large areas in a manner similar to the Morning Glory. Their blossoms are white, opening in early evening to give forth a delicious scent, a factor to remember when you are planning a trellis beside a terrace used in the evening. Planted on a trellis fence, alternating with blu Morning Glories, they give a day and night combination which will keep your trellises in bloom around the clock. In September, Moonflowers stay open in the morning and Morning Glories remain open well into the afternoon, so that they bloom together in many areas at that time. Moonflowers are sometimes perennial in warm climates, and are tender and definitely annual only in the Northern part of the country.
