Often referred to by the common name of Suriname cherry, this plant is only called "cherry" due to a superficial resemblance of bright to dark red, small fruits it produces. A native to tropical eastern South America, this plant naturally grows as a large bush or small tree to 25 feet tall, though can be pruned a fair bit smaller for easier management. Leaves start out pinkish or reddish and fade to green as they age, sometimes also turning red during cooler winter months. Four-petaled white flowers on mature plants give way when pollinated to roughly cherry-sized (but ribbed, pumpkin-shaped) fruits that are extremely sour when greenish or orange, but develop rich sweet flavor when they ripen to deep red or purple. Just don't eat the seeds along with the fruit.
Available plants are seedlings, roughly 3-6 inches tall (photo is a representative of the group).
