Do Raspberries Have Thorns?

Raspberry is a bramble fruit belonging to the Rubus genus (family Rosaceae). Raspberries are a valuable crop across most of northern Europe and Canada, and the US, and they are considered to have originated in eastern Asia. Raspberry fruits are high in vitamin C and antioxidants and are commonly served as a dessert fruit with cream or ice cream. Jams and jellies are popular, and the fruit is frequently used as a pastry filling and a flavoring for liqueurs.

Raspberries are a perennial plant with two-year-long canes. The raspberry bush may be smooth or prickle-armed, and many do not bear fruit until their second year. Depending on the species or cultivar, the canes can grow to be more than 1.8 meters (6 feet) tall and produce more toothed leaflets. The undersides of the leaves are usually hairy and white to grey in color. The five-petaled white to pink blooms yield delicious red, purple, or black fruit (occasionally orange, amber, or pale yellow). Unlike the blackberry, the delicate fruit’s center remains on the vine when harvested. Though the fruit is usually referred to as “berries,” it is actually a collection of drupelets that contain a single seed.

The majority of red raspberries that are used for commercial use are Rubus idaeus and Rubus strigosus cultivars or hybrids. In select locations, two North American black raspberry species are also cultivated commercially; however, the output is limited. Raspberry plants are disease and insect-resistant, but they must be anchored or trellised to keep their wild growth under control. Suckers from the parent plant’s roots are commonly employed to produce red variations; however, leaf or root cuttings are sometimes utilized for quick expansion of new kinds. The arching canes of the black and purple types are reproduced by tip layers, which bury the tips of the shoots approximately 50 mm deep appear during the summer season and dig the rooted tips in early spring.

Canes of Raspberry

Raspberries belong to the Rosaceae family of plants. The canes of most raspberries, like those of roses, are covered in sharp thorns. Raspberry bushes are similar to blackberry shrubs, but instead of normal thorns, raspberry thorns are denser, giving the shrub a “fuzzy” look. The thorns are sharp, despite their “fuzzy” appearance. To avoid harm while pruning or picking raspberries, use gloves, and eye protection.

Plant Characteristics of Raspberry

Raspberry bushes are able to grow up to nine feet tall and provide delicious fruits in the summer. The plants are biannual, with canes bearing fruit the next year. In the spring, colorful blooms emerge, followed by berries in the summer and fall. Harvest time varies according to the variety. Raspberries thrive in good sunshine and healthy soil that is somewhat acidic.

Cultivars with No Thorns

Plants are bred for certain qualities by horticulturists. Most raspberry cultivars developed for a high fruit yield include thorns, so pick a thornless variety if you want a friendlier bush. “Raspberry Shortcake” is a thornless dwarf cultivar with edible berries that grows 2 to 3 feet tall. Canes on the more common 6-foot-tall “Canby Red” cultivar are nearly thornless.

Raspberries Are Easy to Grow

When planting raspberries, place them 1 inch below the soil line for better results. Plants should be spaced at least four feet apart. Remove any canes that produced fruit the previous season in late winter pruning. These ancient canes will no longer bear fruit. In the spring, use a balanced 10-10-10 fertilizer. Fertilizers should be used according to the instructions on the box.
