Long trailing vines with dusty purple coloured berries are a feature of the delicious Boysenberry (Rubus ursinus x idaeus). Thought to be a hybrid between Thornless Blackberry, American Dewberry, Loganberry and Raspberry, the fruit is aromatic.

They are packed with health-promoting antioxidants and important nutrients, including fibre, folate, vitamin K and vitamin C.

Finding them fresh is difficult so grow your own!

Boysenberry nutrition is a good source of fibre and micronutrients, including manganese, folate, vitamin K and vitamin C. It contains powerful antioxidants, including flavonoids that help prevent oxidative damage to the body.

Boysenberry seeds can grow successful and prolifically fruiting plants. However as the Boysenberry is a hybrid between three varieties, not every seed will produce the exact same plant or fruit. Growing from seed is a way to get an interesting range of fruit flavours! Grow all your seeds and pick the most tasty one to propagate from!

The health benefits of boysenberry come from the fruit’s impressive nutrition content, which includes beneficial polyphenols and micronutrients.

1. Promotes Lung Health
A 2016 study conducted on mice published in the American Journal of Physiology evaluated the lung function benefits from increased consumption of fruits high in polyphenols. Researchers found that regular boysenberry consumption has the potential to moderate chronic lung fibrosis in asthma and other chronic pulmonary diseases.

A 2021 study published in Food Science and Nutrition found that drinking boysenberry and apple juice concentrate promoted a shift toward an anti-inflammatory environment within the lungs, and it reduced immune cell infiltration and tissue damage.

2. Supports Cardiovascular Health
A 2014 study found that polyphenol content in boysenberry juice decreased diastolic blood pressure after four weeks. The results also suggest that the nutrients found in the fruit improve endothelial function, which allows for the flow of substances and fluid in and out of tissue.

Another study suggests that the anthocyanins in boysenberry inhibit endothelial dysfunction and contribute to the maintenance of healthy artery homeostasis.

3. Provides Antioxidants
Boysenberry is rich in antioxidants, including flavonoids like anthocyanins. Anthocyanins have been shown in studies to prevent diseases associated with oxidative stress, including cardiovascular and neurodegenerative diseases. The flavonoids also benefit gut health by promoting a healthy balance of bacteria.

A 2015 study published in the Journal of Agricultural and Food Chemistry found that boysenberry seed oil had the strongest oxygen radical absorbance capacity compared to red raspberry, blueberry and marionberry seed oils.

4. Good Source of Fibre
The dietary fibre found in berries like boysenberry have a positive impact on cardiovascular health, digestive health and more. High-fibre foods promote regularity and enhance digestive health, while helping to stabilize blood sugar levels and improve heart health by decreasing LDL cholesterol and promoting blood flow.

5. Provides Vitamin K
Vitamin K foods promote blood sugar control, strong bones and better brain function. A cup of boysenberries contains about 13 percent of your daily value of vitamin K, making it a good source of the important micronutrient.

Data shows that vitamin K deficiency is not uncommon, so getting enough of the nutrient in your daily foods is necessary.

The taste of boysenberry has been likened to that of blackberries but with an extra tang and sweetness. They are thin-skinned and juicy when ripe, a bit bigger than your standard blackberries.

The downside of these unique berries is that they only last a few days after picking, so it’s difficult for commercial growers to get them in grocery stores. For that reason, you’re more likely to see them frozen or canned, but you also have the option of growing your own at home.

The first year, only leaves are produced during the summer. The next season, the berries grow on the plant’s green stems.

Wait until the berries are a dark purple colour and easy to pull off the stem.

Once you have your hands on some boysenberries, it’s time to eat them raw or use them in recipes. Because the fresh berries only last a few days, you may choose to freeze them after harvest.

Simply wash them, lay them out on a baking sheet and put them in the freezer. Once they’re frozen, add them to an airtight bag or container.

Now you can use them in smoothies, a boysenberry pie or tart, or berry-based baked goods.

Any recipe that calls for blackberries or raspberries also works well with boysenberry.

Risks and Side Effects
Some people may experience mild allergic reactions after consuming boysenberry. If you have swelling; itching of the mouth, lips or hands; or stomach discomfort after eating these berries, discontinue use immediately.

People susceptible to kidney stones should minimize their consumption of berries and some other fruits because the oxalates may increase the production of stones.

Grow Notes
Grow in full or part sun. Canes will grow to 2m high and wide, and will spread over the years if not contained within a trellis with yearly pruning. Remove old dead canes in winter, leaving only vigorous healthy canes to produce the next crop.

Plants prefer a rich, well-draining soil, with a pH of 6.0-7.0.

To plant Boysenberries from seed, sow the seeds in a pot starting in mid-winter. Push the seeds about an inch deep and an inch apart into the soil. Cover with a thin layer of sand.

Store the pot in a dim and cool place indoors, such as a pantry or even a garage, and keep the seeds moist by spraying with a spray bottle as needed.

Once temperatures reach above 15°C, place your raspberry pot outdoors.

Once they’ve started to develop leaves and have grown about one inch in height, transplant them in a big pot or in the garden and cover the base around the plant with mulch, leaving the trunk bare to keep the soil nice and moist.

10-40 days

Perennial with fruit on 2 year old canes.
