Simpson's Stopper – A beautiful evergreen tree native to Florida, named for the… plugging effect that the fruits have on the human digestive system. The foliage is small and rounded, with smooth cinnamon-colored bark that makes it an ideal ornamental tree. Although it can grow up to 20 feet tall, John Fairey actually used this tree/shrub as a replacement for boxwoods in several areas of the Garden. When pruned and maintained, the canopy becomes dense and rounded. In spring, small white flowers emerge in the canopy, and are eventually replaced by bright red fruits. These fruits are beloved by native birds, and although they are technically edible to humans, you might end up spending a lot of time in the bathroom if you eat them! Plant in full sun and in well-draining soil. This plant is relatively drought tolerant.
