Mirabilis longiflora (Angels Trumpets) is a shrub-like, tuberous perennial often grown as an annual, with clusters of exquisitely fragrant flowers from summer to fall. Borne in great profusion, its incredibly long, very slender, white trumpets, 6 in long (15 cm), open in the afternoon and release a sweet orange-blossom fragrance. Their purpled fused center provides a purple stamen that protrudes outside the flower accompanied by red colored anthers. The blossoms remain open until the following morning. Mirabilis longiflora is a tender perennial that is killed to the ground by frost, but resprout from its large tuberous roots. It is better to be planted along walkways or near patios where the night-blooming flowers and fragrance can be enjoyed.
