Spathodea campanula (African Tulip Tree) - Widely grown in tropical climates, but sensitive to cold, it was once quite rare in cultivation in California. In the past twenty years, however, this “king of flowering trees” has become a popular landscape tree in frost-free areas of Southern California. It is a large evergreen to 50 feet tall, or more, with flowers throughout the year. When grown in cooler climates (southern California), it is usually smaller to around 25-35 feet tall and 15-25 feet wide. I may act as a deciduous tree, losing its leaves during winter and early spring. Fast growing, moderate water needs.
