The unusual popular name of this medium-sized shrub becomes clear to anyone who observes it over the course of two or three days. Its tubular fragrant flowers change from purple to lavender and then to white over a three day period (First they open as rich lavender blue; then they change to pale lavendar and finally to almost white before they fall). Then all three colors can be seen on the same plant. It grows to about 3-6 ft and does best in filtered sunlight. Perfect houseplant for a bright window. Blooms fall to winter. It's a specimen plant. All parts of a plant are toxic, especially roots and fruits, to a lesser degree leaves.
