moonflower blooming

Ipomoea alba, otherwise known as Moonflowers are so called because they bloom in the evening. They have large 4 to 6 inch fragrant, white or pink flowers on twining vines. The flowers open quickly in the evening and last through the night, remaining open until touched by the morning Sun.

Moonflowers should be planted when the Moon is new or increasing in light!
