The Blackcap: Unveiling the Common Name
The most prominent alternative name for a black raspberry is the blackcap. This name is derived from the berry's appearance and growth habit. When a black raspberry is picked, it leaves a hollow core, much like a cap, on the plant's stem. The term "blackcap raspberry" is also frequently used to emphasize its lineage. This common terminology is important for foragers, gardeners, and culinary enthusiasts alike, as it helps distinguish this unique fruit from other members of the Rubus genus, such as blackberries.
Other Regional and Lesser-Known Monikers
While blackcap is the most common alternative, the black raspberry has acquired a few other regional or historical names. Some of these include:
- Thimbleberry: This name is occasionally used to describe the thimble-shaped, aggregated fruit. However, it is also important to note that Rubus parviflorus is the more formal species name for a different, red-colored thimbleberry native to western North America.
- Scotch Cap: This is another less common term used, mainly referencing the berry's characteristic shape.
- Wild Black Raspberry: This name is used to denote the uncultivated, wild-growing varieties of the plant, which are common in woodlands and fields across eastern and central North America.
Blackcaps vs. Blackberries: The Crucial Difference
Despite their similar names and appearances, black raspberries (blackcaps) and blackberries are distinctly different species within the Rubus genus. The easiest way to tell them apart is by inspecting the fruit once picked. The black raspberry will have a hollow center because the core remains on the plant, while the blackberry will retain its core, making it a solid fruit. The two also differ in size, texture, and flavor, which is a key consideration for both cooking and foraging.
Black Raspberry and Blackberry Comparison
| Feature | Blackcap (Black Raspberry) | Blackberry |
|---|---|---|
| Hollow Core | Yes, fruit detaches, leaving a hollow center. | No, the core remains attached, resulting in a solid fruit. |
| Size | Smaller, often no bigger than a thumbnail. | Larger, up to 1.5 inches long. |
| Flavor | Sweeter and more delicate, with a rich, winey perfume. | Can vary from sweet to tart, generally less delicate than blackcaps. |
| Appearance | Rounder fruit with a matte finish. | More coarsely bumpy and glossy. |
| Stem | Canes often have a distinctive bluish-white bloom. | Does not have the same distinctive bloom as blackcaps. |
Popular Blackcap Raspberry Cultivars
While wild blackcaps are common, several cultivated varieties have been developed for commercial production and home gardening. Some popular black raspberry cultivars include:
- Munger: The primary cultivar used in commercial production in Oregon.
- Jewel: A highly popular variety known for its large size and rich flavor, making it excellent for jams.
- Bristol: A reliable, cold-hardy cultivar suitable for cooler climates.
- Cumberland: Another common variety mentioned in cultivar lists.
Culinary and Health Benefits
Black raspberries, or blackcaps, are a favorite in the kitchen for their intense flavor and color. They can be enjoyed fresh, frozen, or preserved in jams, jellies, and desserts. The berries are also used to make liqueurs and natural colorants. Beyond their flavor, blackcaps are celebrated for their health benefits. They are particularly rich in anthocyanins, which are potent antioxidants responsible for the fruit's deep purple-black hue. Studies have investigated the potential health-protective effects of these compounds.

Conclusion: More Than Just a Berry
From their hollow, cap-like form to their rich, sweet flavor, black raspberries stand out as a beloved wild and cultivated fruit. Their most common alternative name, the blackcap, succinctly describes a key physical characteristic that also serves as the easiest way to differentiate it from a blackberry. Understanding this name and the unique qualities of the blackcap helps gardeners, foragers, and home cooks appreciate this special berry for its distinct place in the culinary world and its robust nutritional profile.
