Blackberry or Mulberry: Which Berry Reigns Supreme?

Blackberry vs. Mulberry comparisons reveal fascinating differences between these similar-looking berries.

Tasty fruits share a spot in the same botanical family yet maintain distinct characteristics all their own.

Most people can easily recognize the blackberry with its glossy dark appearance and slightly tart flavor profile.

In contrast, mulberries tend to grow longer, appearing in various colors from white to deep purple depending on their variety.

The juice from both berries stains fingers and clothing, making them somewhat messy treats during summer harvests.

Many home gardeners appreciate these nutritious fruits for their versatility in jams, pies, and fresh eating.

With so many subtle differences between these berry cousins, you might wonder which one deserves a place in your garden or on your plate.

Let's examine these delicious fruits more closely to help with your berry-related decisions.

Blackberries Overviwe That Every Berry Lover Should Know

Blackberries Overviwe That Every Berry Lover Should Know

Blackberries belong to the Rubus genus within the Rosaceae family and contrary to their name, these aggregate fruits form from merged carpels of a single flower rather than being true berries.

Their exact origins remain mysterious due to numerous varieties existing today, though many can be found throughout Europe and North America.

Unlike typical fruits, blackberries don't grow on trees but instead flourish on thorny brambles or bushes, which requires caution when harvesting to avoid painful pricks.

Garden enthusiasts should consider installing a trellis system for their blackberry plants to prevent them from sprawling uncontrollably and overtaking garden spaces or nearby trees.

Sweet Mulberry Facts to Know

Sweet Mulberry Facts to Know

Mulberries, members of the Mora family, aren't actually berries but rather collective fruits formed from multiple flower carpels. These tasty treats originally come from Asia and Africa, though many regions around the world now grow them.

Unlike their lookalike cousins blackberries, mulberries grow on deciduous trees instead of bushes. The trees themselves vary significantly in size across different species - red mulberry trees typically reach about 40 feet in height, while white mulberry varieties can soar up to 60 feet tall.

Most mulberry trees develop rapidly, often producing fruit after just a few years of growth. Several US states have actually banned male mulberry trees because they release large amounts of mildly toxic pollen that can cause health problems for people nearby.

Blackberries & Mulberries: Similarities

Blackberries & Mulberries: Similarities

Blackberries and mulberries have enough in common to sometimes cause confusion for people trying to distinguish between them. Neither one technically qualifies as a berry - both are actually aggregate or collective fruits packed with antioxidants that help lower chronic disease risks.

These small, edible fruits work interchangeably in many recipes from cereals and fruit salads to baked goods and jams. Due to their perishable nature, both only last about two to three days when refrigerated, though freezing can extend their usefulness for several months.

Both fruits undergo color changes as they ripen, and their intense pigments make excellent natural food colorings. The juice from these non-berry fruits creates vivid stains that add beautiful hues to various dishes.

How Blackberries and Mulberries Stand Apart

Telling these two species apart is actually quite easy once you know what to look for. This table will show you some key points to compare them.

Feature Blackberries Mulberries
Appearance Clusters of small black balls, 1 inch long, turn from green to dark purple/black. Longer, similar width, come in white, purple, black, and red; stain skin easily.
Taste Tangy, sweet with earthy notes; core can be bitter if unripe. Sweeter and juicier with mild tartness; best when fully ripe.
Leaves Compound leaves with 3–5 oval leaflets; support oral health and immunity. Oblong, serrated leaves; used for silkworms; aid blood pressure and sugar control.
Nutrition High fiber, vitamins (esp. C), low fat; good for digestion and weight control. Similar nutrients; rich in vitamin C; boosts immunity and circulation.
Season Harvest July–August, sometimes late June for early types. Two seasons: March–May and October–November; harvest when ripe.

Appearance

Appearance

Mulberries and blackberries have similar shapes and colors but can be distinguished by certain traits. Blackberries look like clusters of small black spheres arranged around a center, about 1 inch long and 0.8 inches wide. They change color from green to red, then dark purple-black when ripe.

Mulberries, on the other hand, are about twice as long as blackberries but share the same width. They appear elongated and can be white, purple, black, or red.

Mulberries also tend to stain your hands more easily when handled.

Taste

Taste

Blackberries offer a sweet yet tangy flavor with earthy undertones and a woody core, which some find slightly bitter if unripe. Removing the seeds and core can reduce bitterness.

Mulberries are generally sweeter and juicier with a milder tartness. They are smoother due to pectin content and sometimes described as tasting like a blend of grapefruit and blueberries.

The best flavor comes from fully ripe mulberries; unripe ones tend to be sour and harsh.

Leaves

Leaves

Blackberries grow on bushes with compound leaves that have three to five oval leaflets. These leaves have health benefits like improving oral health and boosting immunity.

Mulberry trees produce oblong leaves with serrated edges and up to four lobes. Mulberry leaves are important for silkworm cultivation and offer health benefits such as blood pressure regulation and blood sugar control.

Nutritional Values

Blackberries are fiber-rich, support digestive and dental health, and suit low-fat diets. Mulberries excel in vitamin C content, aiding immune support and blood circulation.

Season

Blackberries are typically harvested in mid to late summer, from July through August, with some early varieties appearing in late June. Mulberries fruit twice a year: once in spring (March to May) and again in fall (October to November).

Waiting for full ripeness is key to enjoying the best flavor in both berries.

In The Refrigerator

When storing blackberries in the refrigerator, it’s best to keep them unwashed in their original packaging or a breathable container. This helps prevent excess moisture buildup, which can cause mold and spoilage.

Blackberries typically stay fresh for about 3 to 6 days when refrigerated under these conditions. Mulberries, being more delicate, should be stored in a shallow container lined with paper towels to absorb moisture.

They should be covered loosely with plastic wrap or a lid to allow some air circulation. However, mulberries generally have a shorter refrigerated shelf life, lasting only about 1 to 2 days before they start to spoil.

In The Freezer

In The Freezer

For longer storage, both blackberries and mulberries freeze well but require proper preparation. Blackberries should be spread out on a baking sheet in a single layer to freeze individually before transferring to airtight freezer bags.

This method helps preserve their shape and flavor by preventing the berries from sticking together. Similarly, mulberries should be gently rinsed and thoroughly dried before freezing.

They can also be frozen individually on a tray and then packed into freezer bags once solid. Freezing helps maintain the flavor and texture of these berries, making it easy to enjoy them year-round in smoothies, desserts, or cooking.

Other Ways to Store

Other Ways to Store

Dehydrating removes moisture from blackberries and mulberries, extending their shelf life and concentrating their flavor. Dried berries are chewy and great for snacks or baking.

Puree the berries, spread thin, and dry to make fruit leather - a sweet, chewy snack that stores well at room temperature for weeks.
