With the setting of the sun, the nocturnal garden awakens and the night shift takes
Many plants bloom exclusively at night. Many more wait to release their heady scent until
evening. White flowers and plants with variegated foliage glow softly as they reflect the
moonlight. To those who work all day, the garden can be a peaceful refuge in the evening.
For others, the work goes on. The bright blooms of some plants and the heavenly scent of
others attract nectar-feeding moths and bats. These are the pollinators that work only
after dark. Other bats, also drawn to the night-blooming garden, are there to prey on
insects. They can each consume 600 mosquitoes per hour.
Why not join the night shift and plan your garden around the time when you can most enjoy
it? When planting a garden that will shine at night, be sure to include varieties from
each of these categories:
Night Flowering Plants
- Evening Primrose: (Oenothera) With
sweetly-scented blossoms of soft white, pink and bright yellow that open in the evening,
this fast-spreading perennial is hardy in zones 5-9.

night-blooming relative of the morning glory perfumes the garden as its large 5 to 6 inch
white flowers open at dusk. A quick growing climber with large heart-shaped leaves.
- Angel's Trumpet: (Datura innoxia) Huge
6 inch white flowers appear from midsummer until frost on this viney annual, opening at
night and remaining open well into the following day. They have a delicious fragrance,
especially in the evening. Grows 3 to 4 feet tall and wide with an abundance of blue-green
foliage. Warning: this plant is poisonous and should be kept away from children.

on, they open releasing a honey/almond/vanilla fragrance.

jasmine-like perfume. Found in the gardens of Thomas Jefferson at Monticello, the bushy
plants grow 24 inches tall and are an annual in our climate.

a scent that is reminiscent of hyacinths, flowers open on three successive nights before
fading. They are native to England.
