Rubus caesius/The dewberries are a group of species in the genus Rubus, section Rubus, closely related to the blackberries. They are small trailing (rather than upright or high-arching) brambles with aggregate fruits, reminiscent of the raspberry, but are usually purple to black instead of red.
Dewberries are common throughout most of the Northern Hemisphere and are thought of as a beneficial weed. The leaves can be used to make herbal tea, and the berries are edible and taste sweet. They can be eaten raw or used to make cobbler, jam, or pie. Alternatively, they are sometimes referred to as ground berries.
Around March and April, the plants start to grow white flowers that develop into small green berries. The tiny green berries grow red and then a deep purple-blue as they ripen. When the berries are ripe, they are tender and difficult to pick in any quantity without squashing them. The plants do not have upright canes like some other Rubus species but have stems that trail along the ground, putting forth new roots along the length of the stem. The stems are covered with fine spines or stickers. The berries are sweet and, for many, less seedy than blackberries.

Rubus caesius is a Eurasian species of dewberry, commonly known as the European dewberry. Just like other dewberries, it is a species of flowering plant in the rose family (Rosaceae), related to the blackberry. The plant is widely distributed across much of Europe and Asia from Ireland and Portugal as far east as Xinjiang Province in western China. It has also become economically naturalized in distributed locations in Argentina, Canada, and the United States. European dewberry, Dewberry, Common Dewberry, blue bramble, and youngberry are a few of the most popular common names of the plant. It is a low-growing perennial and is often heavily armed with prickles. It bears edible fruits that can be eaten raw or baked into cobblers or pies or made into preserves. They are occasionally cultivated but can spread rapidly and are considered to be weeds in many areas.
Plant description
Dewberry is a small low-growing, deciduous shrub that normally grows about 2 m (6 ft. 7 in) tall with biennial stems which die after fruiting in their second year. It sends out long runners which root at the tip to form new plants. Rubus caesius is similar to and often confused with forms of Rubus fruticosus. The plant is found growing in hedgerows, amongst shrubs, in rough dry meadowland, forest margins, copies, rocky broadleaf woods, waterside thickets, roadsides, mid-successional dunes, riverbanks, valleys, ravines, streams, inundated meadows, gardens, and orchards. The plant prefers light, medium, and heavy soils, slightly acidic to basic and well-drained soil. The stems are bluish-grey and sometimes prickly. Cane is 1.5 m tall and 0.5-2 m long, armed with irregular-sized prickles, greenish-yellow to brown, and glabrous to glabrescent.
Leaves
The alternate leaves are hairy above and below. Petioles are 4-6 cm long, armed, and often glandular. The lanceolate stipules are 0.6-1 cm long and 0.2-0.3 cm broad, bearing hairs and marginal glands. The leaves are alternately arranged and trifoliate (rarely five). Each leaflet is thin, broadly ovate to almost round, 4-7 cm long, and 3-7 cm broad, basally round, apically acute, with doubly serrate margins. The blade is somewhat pubescent, lighter green abaxially. The lateral leaflets are nearly sessile, while the terminal leaflets have a 1-2.5 cm long petiolule and are armed and glandular.
Flower
The corymbose inflorescence can be axillary or terminal and bears at least 10 flowers. The terminal inflorescences (up to 14 cm long) are longer and bear more flowers than the axillary inflorescences. The inflorescences are almost perpendicular to the floricanes. The pedicel (1-1.5 cm long) and rachis are pubescent, often glandular, and armed with very small prickles. The broadly lanceolate bracts are pubescent or glandular-pubescent, 0.5-0.8 cm long and 0.1-0.2 cm broad. The perfect, white flowers are up to 6 cm across and have a 5-parted calyx and corolla. The outer surface of the calyx is pubescent and occasionally armed with minute prickles. Sepals are long acuminate, 0.6-0.8 cm long, and 0.3-0.5 cm wide. The white corolla is glabrous, and the obovate petals are basally clawed, 0.8-2 cm long. Stamens are numerous, borne on a hypanthium, relatively shorter than the petals, but often longer than the glabrous pistils. Numerous ovaries are unilocular and bear 2 ovules, of which only one will become a seed, the styles are filiform and stigmas capitate. Flowering normally takes place from June to September.
Fruit
The fruit is a glaucous, bluish-black aggregate of few fleshy drupelets with a bluish waxy bloom. Drupelets are covered by blue cuticula and cannot separate from their fleshy receptacles readily. The drupe is approximately 1 cm in diameter, and nearly round. The drupelets are irregular-sized, and each contains one seed. Each fruit consist of not more than 20 drupelets. The single drupelet is composed of three layers: external: thin exocarp, medium: fleshy mesocarp, and internal: hard endocarp. Each drupelet has one hard seed inside. The reticulate seeds are rather hard and heavy (0.37 g), and are 2.2-3.2 mm long and 1.3-2 mm wide. The seed coat is composed of three layers: exotesta, mesotesta and internal endotesta.
Health benefits of Dewberry
Dewberry has low calories and consists of vitamins A and C, some protein, magnesium, zinc, copper. Let’s check out some of the impressive benefits offered by dewberries
1. Prevents Cancer
Including dewberries in your diet on a regular basis may help prevent cancer from striking. All of the antioxidants they contain help reduce oxidative stress, something that is often blamed for cancer development.
2. Reduce High Blood Pressure
Doctors say that the reduction of bad cholesterol can help lower blood pressure. But since dewberries have good amounts of potassium, too, their high blood pressure-lowering properties are considerably increased.
3. Lower Bad Cholesterol
Because of loads of antioxidants present in dewberries, regularly consuming them can help in lowering the levels of bad cholesterol in the blood. As a result, the arteries can be kept from ending up clogged.
4. Ward off Infections
One of the numerous minerals present in dewberries is zinc. Since this nutrient is significant for stimulating some of the cells of your immune system, your risk of having an infection like the cold or flu can be noticeably lowered.
5. Healthy Skin
Vitamin C present in dewberries is a well-known immune booster. Vitamin C is also respected for its capability to promote the healing of wounds as well as various problems regarding the skin.
6. Cure Eye problems
Vitamin A found sufficiently in dewberries is quite beneficial for curing eye problems. Eye specialists say that this nutrient is mainly vital for keeping the vision 20/20, and also in warding off all sorts of eye diseases that can lead to loss of vision.
7. Slow Down Skin Aging
Beauty-conscious individuals who like to stay looking young forever should consume dewberries frequently. That’s due to the fact that their vitamin C content is important for the production of collagen that delays the formation of wrinkles.
8. Prevents Constipation
If you are suffering from constipation, dewberry is one of the best options for curing them. It is a wonderful idea for you to include more dewberries in your diet. Because of their fiber and water content, the removal of waste products in the colon can be facilitated.
9. Keep Excess Pounds at Bay
Since fiber in dewberries is heavy on the stomach, consuming these blackberry look-alike can help ward off cravings and hunger pangs, thus helping to make those excess pounds go away or from creeping in.
10. Keep Gums and Teeth Strong
Vitamin C found in dewberries is also necessitated by the gums for it to remain healthy. This results in much tougher teeth that are able to resist cavities. So if you want to keep your smile intact, regularly snack on dewberries.

- Remove from heat and stir in the vanilla extract. The syrup will thicken a bit as it cools, but if it thickens too much, you can thin it with a little more lemon juice or water.
Dewberry and Apple Puff Pastry Tarts
Ingredients
- 275 g dewberries or blackberries
- 250 g puff pastry
- 1 small apple ( 85 g) preferably a sweet/tart variety, e.g. Ashmead’s Kernel
- 25 g raw sugar (2 tbsp.) plus a little more for sprinkling
- 1 small sprig of fresh rosemary
Instructions
- Preheat your oven to 400° F (200° C).
