Answer: Trachelium caeruleum, or Curry Plant is an excellent semi-evergreen perennial for hot climate, low-irrigation gardens, and is especially useful for providing color in the difficult situation of dry shade.The leaves are shiny green, narrowly oblong and notched along the edges. Depending on how cold the winter is, they are either evergreen or deciduous or somewhere in between. The flowers are large flattened clusters of tiny blue (sometimes white seedlings appear) flowers. The clusters are held above the foliage like flattened blue clouds, and side-shoots with smaller clusters continue to bloom for along time in early summer. The flowers are fragrant, and are excellent cut flowers.
Trachelium will grow and bloom with just a few hours of sunlight a day, and when grown in a shady location, is amazingly tolerant of dry soil and competition from tree roots. Continuously wet soil or poor drainage usually mean short plant life. Full sun is accepted, but more regular irrigation will be required in a hot sunny situation.
