Moonflower Vine – Night Blooming Flowers
The Moonflower Vine (also known as Moon Plant, Moon Vine, and Ipomoea
alba) is a dramatic tropical vine that puts on a beautiful display of
large, white, night-blooming flowers.
The large, white moon flowers, which are five to six inches (12 – 15
cm) across, are surrounded by heart shaped leaves that are a rich, deep
green color and four to eight inches (10 – 20 cm) long.
Moonflower Vine is native to tropical America. It can grow up to
sixteen feet tall, and should be planted near some type of vertical
support, such as a trellis, fence, or wall.
It can be grown as an annual in any hardiness zone during warm weather.
In USDA Hardiness Zones 9 – 11, it grows as a perennial.
The flowers are fragrant and bloom during warm summer evenings. As the
sun sets in the late afternoon, the flowers open, releasing a sweet
fragrance. As the sun rises, the blooms slowly spiral closed.
Vine Information and Plant Care Tips
USDA Hardiness Zone
USDA Zone 9 - 11
Full sun - will benefit from some direct sunlight.
Keep soil moist, not soggy. Water regularly, avoid overwatering.
Do not over fertilize this perennial flowering vine. Over fertilization
could result in an abundance of leaves and few flowers.
Collect seeds for propagation when the husks that follow the white
moonflower blooms become black and dry out. Store seeds in a dry place.
To prepare moonflower seeds for planting, nick the seeds with a knife.
Soak the seeds in water overnight to promote germination.
After the danger of frost has past, seeds can be planted directly into
Select a location with well-draining soil.
Plant 2-3 seeds about 1 inch deep.
Moonflower vines will need some type of support as they grow – they can
grow up to 16 feet tall
Water the plants regularly. Soil should be kept evenly moist.
Requires minimal feeding - fertilize with liquid plant fertilizer, once
or twice later in the summer.
Grows best in moist, well-drained soil.
Pests and Diseases
Insect and disease problems are minimal. Insecticides, repellents or
fungicide should be applied as needed.
Display and Uses
Moon vine can be planted in hanging baskets or pots. If planted in a
traditional pot, provide some type of support, such as a small trellis.
Support is necessary when planted in the landscape as well; plant near
a trellis, wall, or fence.
Tips for Propagating and Planting
- To prepare moonflower seeds for planting, nick the seeds
with a knife. Soak the seeds in water overnight to promote germination.
- Plant seeds in peat pots. Fill the peat pots with soil-less
planting medium. Potting soil should be 3/4 inch below the pot's rim.
Moisten soil with water. Place 2 to 3 seeds on the soil. Cover seeds
with ½ inch of potting mix. Water seeds gently.
- Planted seeds should be kept in a warm, moist location
until the seedlings are ready to be transplanted. The best time to
start vines indoors is 4 to 6 weeks before the last expected frost.
Seeds will germinate in approximately three weeks.
- Seedlings can be planted when they have grown two or three
leaves. When you are ready to plant, limit seedlings to one vine per
pot. Extra seedlings can be removed by cutting them with scissors. Do
not pull them out of the soil - this could damage the roots of the
remaining seedling. Seedlings that are ready for planting should have
formed 2 or 3 leaves.
- Select a location that receives bright sunshine (direct sun
is ideal). This tropical vine prefers a sunny location; however, it
will tolerate light shade. A moist, well-draining soil is preferred.
Also, climbing vines need vertical support, such as a fence, trellis,
- Loosen the soil in the selected planting area. Dig a hole
slightly wider than the peat pot, matching the depth. Place the potted
seedling in the hole and lightly cover with the original soil.
The peat pot will
eventually disintegrate in the soil, providing the soil with added
nutrients. Gently water the transplanted seedling.
