Imagine an all white garden under a full moon. White flowers and gray foliage plants bring a magical light to the night garden.

Here are seven easy to grow white-flowering plants that can easily be started from seed - with a surprise at the end.

*Shasta Daisy. "I love the white daisies," Casper gardener Jo Ann Bishop said. "I always love white flowers because they're such a beautiful contrast against the green. It's always been one of my favorite flower colors n they sparkle, stand out from the other flowers," she said.

She also loves to see white iris, narcissus and white hyacinths in her garden. "They are spectacular and I love white roses, too."

We digress. We must get back to Shasta Daisies.

Shasta Daisies grow to a stately 30 to 36 inches tall, giving the gardener great, long stems ideal for cutting. The large, single, white flowers have distinctive yellow centers. This is an excellent plant to use in mid-bed plantings in perennial or landscape borders. Very easy to grow.

"They're so dependable," said another avid Casper gardener, Barbara Grace. "They're a stand by for everybody and a great cutting flower."

*Alyssum. Bishop says alyssum is a good one for right beside the patio or walk.

"In the moonlight, it really shows up," she said.

Alyssum, with its tiny white flowers in delicate balls, rewards gardeners with flowers from spring till hard frost. An effective ground cover, alyssum often re-seeds herself. She will grow to only about four inches high in a dense, compact growth habit.

Alyssum is fun to put on the edges of hanging baskets, too, reliably trailing gracefully down the sides. Because bees like alyssum as much as we do, though, never plant her next to a swimming pool or seating area.

*Baby's Breath. Her dainty white flowers move with the slightest evening breeze, as though they're dancing in the dark. Easy to grow, this top-notch flower is very popular in flower arrangements, either fresh or dried.

*Dahlias. A white dahlia, with her clustered florets, offers an impressive bloom held high on strong stems that face upward or outward, catching all the light. Dahlias are grown from tubers, usually started inside in early spring then transplanted to the garden after warm weather is assured. When fall approaches, you will lift the tubers and store them where they won't freeze, then replant them next year.

*Moonshadow sunflower. A new hybrid, this white sunflower should attract lots of attention in your garden. And in your bouquets. Sunflower stems are sturdy n sturdy enough even for our windy climes n especially when they're relatively short by sunflower standards. Grow this beautiful flower in full sun.

*Polianthus. Another one grown from a giant seed n in this case, a bulb. Mom used to call this one a "tuberose." Polianthus, or tuberose, has a powerfully sweet aroma and will stand tall surrounded by grass-like leaves about 18 inches tall.

Polly will need four months of warm weather before she thinks about blooming, so it's a good idea to pot her up inside, too. When you put her outdoors, set the rhizome about two inches deep and acidify the soil. Used tea leaves and coffee grounds are appreciated in the flower garden. Be sure to lift the rhizome in the fall, along with the dahlias.

*Moonflower. Queen of the night garden. She will clamber up and over a trellis or arbor in no time - 20 or 30 feet is nothing for her - and emit a lovely fragrance from her six-inch white flowers while she's at it. Her leaves are heart-shaped and thickly spaced over her vine, lending shade to the structure.

Did we mention that Moonflower's blossoms typically show off after sundown and into the night? She'll even open them up on cloudy, dark days.

Now for the surprise. Drop a line to Catherine Walworth, in care of The Casper Star-Tribune, P.O. Box 80, Casper, WY 82602, listing all seven of the flowers we talked about here.
