The moonflower is a vigorous twining vine that is very fast growing in really hot weather. It is a tender tropical perennial but is now seeing popular use as an annual vine in colder areas. This close relative of the morning glory has similar heart shaped leaves that are a rich green and 4-8 inches long. They provide a beautiful backdrop for the spectacular moonflowers. This vine also known as the evening glory as its buds open in late afternoon and last only until morning's light transforms them into a limp shriveled mass. Moonflower makes up for the brief lifespans of individual flowers by producing quantities of the big blossoms throughout the summer. These are held on a stem that bears several buds simultaneously, not all of which bloom the same night. The long 4 in buds are also very attractive especially in the hours just before the flower opens.
And what a fabulous flower the moon vine (as it is also called) produces! They are fluted funnels sculpted in purest alabaster white. About the diameter of a saucer measuring 5-6 inches across. As if the moonflower was not already enchanting enough, it also has a delightful fragrance to complement its beauty and perfume warm summer nights.
Leaves and flower stems are adjacent and on the same side of the stem. The flowers are followed by rough husks that are filled with seed which can be harvested when the covering turns dry and black.
Morning glory can be direct seeded into the soil after the last frost, but you will have much earlier blooms if you plant indoors 5-6 weeks ahead of time. They are a little tricky to transfer. Use little peat pots that can be put directly into the soil where you want the plant to grow. The seed of the morning glory is very hard. I soak mine overnight before planting to soften the hard shell. Growing morning glories is easy; keeping them where you want them is a little more difficult. You will notice that soon after a bloom fades a perfectly round capsule forms. This is full of tiny black seeds. Once it dries the capsule opens and morning glory seeds drop everywhere. Unless you are so diligent as to cut off EVERY pod they will spread and reseed.
