This flower is an heirloom flower and the name indicates the time of day when the plants trumpet-shaped flowers open. The flowers open in late afternoon, in response to a temperature drop. Nocturnal moths and other nighttime pollinators are attracted to their nectar. The name of the plant also goes by "Marvel of Peru" due to its native South American habitat.
The flower is hardy and grown as a perennial in zones 7b-11, but gardeners in other zones often grow these beauties as annuals. They will self-sow also. They can grow to four feet tall and three feet wide. They are heat and drought tolerant and are a favorite of hummingbirds, bees and butterflies.
And the scent is very fragrant and similar to lillies.
"Just living is not enough...one must have sunshine, freedom, and a little flower."
