Italian plums, often referred to as Italian prune plums, are distinct for their uncommonly egg-shaped appearance and deep purple to blue skin, which is typically covered with a powdery white/blue "bloom" similar to that found on blueberries. This natural bloom is a protective wax coating.
Distinctive Features of Italian Plums
These plums are immediately recognizable by several key characteristics that set them apart from other plum varieties.
Shape and Size
Italian plums are typically small to medium in size. Their most notable feature is their elongated, oval, or egg-shaped form, rather than the rounder shape commonly associated with many other plum types.
Skin Color and Texture
The skin is a striking deep purple to blue hue. It's smooth to the touch, but often has a delicate, dusty coating known as a "bloom." This bloom is a natural phenomenon, indicating freshness and helping to protect the fruit.
The "Bloom" Explained
The powdery white/blue bloom is a thin, waxy layer naturally produced by the plum. It's perfectly safe to eat and is often seen as a sign of quality and freshness, as it helps to prevent moisture loss and spoilage.
Origins and Cultivation
Italian prune plums are named for their native growing region, flourishing particularly along Italy's Mediterranean coastline. Their ability to dry well into prunes without fermenting around the pit is why they are often called "prune plums."

| Skin Texture | Smooth, often with a powdery white/blue "bloom" |
Why Their Appearance Matters
The unique appearance of Italian plums isn't just for show; it contributes to their utility. Their firm flesh and relatively small pit make them ideal for drying into prunes, cooking, and baking, as well as for fresh eating.
