Cestrum 'Newellii' at the Atlanta Botanical Gardens, blooming nicely in July 2003. The bay-like, very dark leaves and dark purple stems are of wonderful substance and character. The thick, waxy red inflorescences are quite different for a bedding plant as this was and is used elsewhere. It is really a tropical shrub and can be grown (among other species of the genus) in USDA zones 9-10 as a woody landscape plant. One is more apt to run into the genus for the first time in a large conservatory planting where various taxa are cultivated to floral perfection. The particular cultivar  has been around since 1876 but is truly a new plant for most of us.

Birds and insects of various types are attracted to the flowers and often to any fruits that develop. Most are fragrant too.
