How Do I Germinate Moonflower Seeds?


Moonflowers are a popular plant for both white-toned gardens and evening gardens. The vines produce large, trumpet-shaped blossoms similar in appearance to morning glories. These scented blooms can be as large as 6 inches in diameter in shades of white or pink and they open in the evening hours. Typically the blossoms will remain open all night before wilting and falling off of the plant before the next morning. In tropical regions, moonflowers are a perennial plant; however, in northern latitudes the vine is treated as an annual.

Step 1

Wait until early spring after your last average frost date.

Step 2

Nick the surface of each moonflower seed with a knife. This is a process called scarification. Moonflower seeds will not germinate unless they have been nicked.

Step 3

Fill a bowl with lukewarm water and place the moonflower seeds into the bowl. Allow the seeds to soak overnight.

Step 4

Dig a furrow beneath a trellis in a sunny location. The furrow should be 1/4 of an inch deep.

Step 5

Place the moonflower seeds into the furrow and cover with soil. Water the seeds to spur on germination. The seeds should sprout in two to three weeks.
