An Italian plum or prune is a type of small fruit-bearing tree native to Europe. Also called fellenburg, the Italian plum is often planted by homeowners wishing to grow edible fruit on their property. Reaching heights of 15–20 feet (4.6–6.1 m), full-grown Italian plum trees have a spread slightly wider than their height. Italian plum trees are drought tolerant and good in high heat and humidity environments. They generally need about six hours of full sunlight a day. Late bloomers, Italian plum trees do not flower until late spring. Their flowers consist of numerous small white or pink blossoms which occur singly. They have dark green leaves. Between three and five years after an Italian plum is planted, it will begin producing fruit. Each year afterward its fruit production will increase until it reaches its peak at about ten years. The tree will continue its maximum fruit production for five to ten years after it reaches its peak.
