Blooming over an incredibly long season, Mirabilis multiflora (Colorado Four O'Clock) is a tuberous hardy perennial of sprawling and dense habit, boasting a profusion of fragrant, vibrant deep pink, broadly tubular flowers from spring to fall. Blooming in the leaf axils and in clusters at the tips of the numerous slender but much-branched stems, the large blossoms, up to 2 in. long (5 cm), open in the afternoon and close in the morning. They attract night insects as well as pollen-collecting bees, hummingbirds and quails. The showy flowers are nestled against the lush foliage of blue-green heart shaped leaves. Fast-growing, long-lived, drought tolerant and undemanding, Mirabilis multiflora has a commanding presence in the garden. It is spectacular as a ground cover, great for erosion control (thanks to its extensive root system), and is lovely cascading voluptuously a retaining wall. Place it along walkways or near patios where the night-blooming flowers and fragrance can be enjoyed. Mirabilis multiflora dies back in freezing winters, but resprouts from its large tuberous roots.
