This is an unusual shrubby Impatiens from Madagascar, called Impatiens bicaudata. I received this as a cutting from a friend and within a year it grew to a height of around 1.8 m, developed a stout trunk, and hasn't stopped flowering. The orange and yellow curled flowers are like a flock of tiny, exotic birds, or perhaps a school of open-mouthed goldfish! The lush-leaved plant grows in part to full shade, liking well-drained soil but appreciating some moisture, especially during the warmer months. It is cold sensitive, so I cut it back in mid-August. It grows readily from cuttings. My shrub grows with red-flowered cane Begonia and shade-tolerant Salvia splendens in scarlet tones.
