As a vine, the Moonflower can climb to an approximate height of 16 feet. 
The vines produce the beautiful flowers come late summer. They don’t require much space in the garden, as the Moonflower plant grows upwards! You’ll love the unique heart-shaped leaves as much as the pure white blooms itself as it shoots towards the moon!
For best results to display this fast-growing vine, plant using a trellis suitable to support the plant’s growth. They love to grow on anything and everything they can get their “hands” on! If you find the growth a bit too overwhelming, pinch the Moonflowers at the top.

The Moonflower plant does best growing in full sun, during warmer months but will grow in partial as well. If possible, position the moon vine near sunny patios and avoid garages or the side of a house, which could block the sun’s rays for much of the day.

Plant in a well-drained soil that doesn’t contain too much clay. Keep soil appropriately moist but not too soggy. For added encouragement, add a layer of compost and water deeply once or twice a week, more if you’re experiencing a dry spell. It’s better to under-water rather than overwater, as it can affect the flower’s quality as they grow. The addition of fertilizer isn’t needed if the soil is fertile.

These plants can survive a light frost spell, but cannot bear severe to heavy frost. In colder zones, plant the moonflower vine in a large container to move indoors when the winter season arrives. Prune vines back and keep in a warm, sunny location.

Plant Propagation
Plant Moonflower seeds indoors, 1/2 inch deep, 4 to 6 weeks before the frost arrives. Soak seeds overnight in warm water or carefully nick the hard shell before planting to allow for easy emergence. If you wish to skip the transplanting, plant seeds outside directly after the last winter frost passes.

Keep the temperature in the 65 to 85 degrees F, range and expect germination anywhere from 4 to 7 days.  Place seedling 6-inch apart to allow for good air flow, and water the soil thoroughly once.

The Moonflower vine makes a great addition to an outdoor space wheel flowers and fragrance can be enjoyed once the sun goes down.
