Scientific Name (Genus/Species): Mirabilis longiflora
Family: (Nyctaginaceae)
(TP) to 3.5′. Sweet Four o’Clock, Angel’s Trumpets. Texas, Arizona and Mexico. Extraordinary, six-inch long, very slender, white trumpets are borne in great profusion on mounds of sticky, bright apple-green foliage. The flowers release a sweet orange-blossom fragrance in the evening. These unusually long flowers need a special pollinator with an extended proboscis, such as the Hawkmoth. The Hawkmoth is similar to the Hummingbird in that they hover in place and unfurl their proboscis and drink the sucrose-rich nectar they require, thus creating a mutually beneficial relationship. Lift and store the swollen tubers over winter as you would a Dahlia. Blooms midsummer to fall. Sun/partial shade. 4 & T3
