Did You Know?
1. Contrary to popular belief, blackberry bushes do have thorns. However, not all varieties of blackberry bushes have thorns, as there are some thornless cultivars available.
2. The thorns on blackberry bushes serve as a form of protection for the plant against herbivores. They also help the plant climb and attach themselves to nearby structures or shrubs for support.
3. The technical term for the thorns on blackberry bushes is “prickles.” Prickles are sharp, stiff outgrowths from the plant’s epidermis, and they can be painful to human skin if not handled with caution.
4. Blackberry bush thorns are modified branches, equipped with a hardened outer layer called the cuticle, which acts as a shield against pathogens and physical damage.
5. Some species of blackberry bushes have thorns that are hooked, making it easier for the plant to latch onto objects and disperse seeds. These thorny hooks are an adaptation to enhance the blackberry bush’s survival and reproduction.
Blackberry Bushes: The Prickly Facts
Blackberry bushes, scientifically known as Rubus fruticosus, are famous for their sharp prickles on the first- and second-year shoots. These prickles serve as a natural defense mechanism, protecting the plant from herbivores. When coming into contact with a blackberry bush, the prickles can be painful. It is worth mentioning that certain types of blackberry bushes are thornless. The University of Arkansas researchers have successfully developed prickle-free cultivars.
The Growth And Habitat Of Blackberry Shrubs
Blackberry shrubs have the ability to thrive in a wide range of environments, including woods, scrub, hillsides, and hedgerows. They can adapt to different soil types, making them resilient and adaptable. Unmanaged mature blackberry plants tend to form a tangle of arching stems, creating dense thickets, which provide shelter and food sources for various animals and birds.
The Importance Of Pollination For Blackberries
Blackberry bushes depend on pollinators to produce fruits. The flowers of these bushes bloom in late spring and early summer, showcasing beautiful white or pale pink petals. Successful pollination and fruit set require sufficient visits from pollinators. Insufficient visits can result in underdeveloped ovules and incomplete drupelet development. Factors like weather conditions and habitat loss can influence pollinator populations and consequently affect the yield and quality of blackberries.
Blackberries: From Ancient Delicacy To Modern Uses
Blackberries have a long history of consumption, dating back to around 2,500 years ago. Ancient civilizations recognized the deliciousness and nutritional value of blackberries. Over time, blackberries have been used in a variety of culinary creations, including wines, cordials, pies, jellies, and jams. They are also highly versatile and have been utilized in traditional medicine, dyeing fabrics, and even making rope.
In the modern era, significant advancements in hybridization and cultivar development have taken place, primarily in the United States. The loganberry, a hybrid of blackberry and raspberry, was developed in Santa Cruz, California in 1880. Additionally, thornless varieties of blackberries were introduced in the 1920s, providing consumers with a more pleasant harvesting experience.
Blackberry production has expanded globally, and Mexico has emerged as a major player in the market. In 2017, Mexico accounted for 97% of the market share for fresh blackberries imported into the United States. Chile, on the other hand, held 61% of the market share for American imports of frozen blackberries. The Mexican industry is dominated by the Brazilian blackberry cultivar ‘Tupy‘, which is suspected to have the ‘Boysenberry‘ as its male parent.
To stimulate flower bud development in regions with no winter chilling, chemical defoliation and growth regulators are employed in Mexico. Blackberries face similar diseases and pests as raspberries. Some common pests that affect blackberries include the spotted-wing drosophila, blackberry aphid, raspberry beetle, raspberry moth, and strawberry blossom weevil. Thankfully, the loci that control primocane fruiting and thorns/thornlessness in blackberries have been mapped, allowing for targeted breeding and genetic improvement.
Interestingly, folklore in the UK and Ireland advises against picking blackberries after 11 October as they may be fouled by the devil or a Púca. This myth adds a touch of mystery to the blackberry harvesting season, adding to the allure and excitement of enjoying these delightful fruits.
Blackberry bushes do indeed have thorns, although prickle-free cultivars have been developed. These versatile plants can grow in various habitats and rely on pollinators for successful fruit production. From ancient times to the present, blackberries have been cherished for their delicious taste and used for diverse culinary and practical purposes. The industry has seen remarkable advancements and expansion, with Mexico emerging as a dominant player in the global market. However, the allure of blackberries also comes with some challenges, as pests and diseases pose a threat. With ongoing research and development, blackberries continue to captivate our taste buds and contribute to a rich cultural heritage.

Frequently Asked Questions
What is the difference between a blackberry bush and a blackberry tree?
The main difference between a blackberry bush and a blackberry tree lies in their structure and growth pattern. A blackberry bush is a small shrub that grows in trailing vines, characterized by its ability to produce tasty edible blackberries. On the other hand, a blackberry tree does not truly exist in the traditional sense. While the blackberry plant can have a tree-like appearance due to its woody stems and branches, it is technically classified as a shrub rather than a true tree. Therefore, the distinction between the two lies in the terminology and the perceptions of individuals.
Do blackberries have prickles?
Yes, blackberries do have prickles. These prickles can vary in size and shape, ranging from curved to straight, and can be found on green, purplish, or red stems. However, it’s important to note that not all blackberry stems have prickles – some may be smooth or only moderately hairy. These prickles serve as a protective mechanism for the plant, helping to deter potential predators or unwanted contact with humans.
Are blackberry leaves spiky?
Yes, blackberry leaves are indeed spiky. Their palmately compound structure consists of five leaflets, each containing deeply toothed subleaflets with jagged, thorny tips. These spikes serve as a natural defense mechanism, potentially deterring animals or humans from handling or consuming the plant. Therefore, caution should be exercised while handling blackberry leaves to avoid any unwanted pricks or scratches.
Why do blackberry bushes have thorns?
Blackberry bushes have thorns as a defense mechanism against predators and to aid in their growth. The thorns act as a deterrent, preventing animals from easily accessing the delicious berries. Additionally, these prickles help the blackberry bushes intertwine with each other and with neighboring plants, creating a network that keeps the bushes lifted off the ground. This elevation allows for better exposure to sunlight and airflow, promoting healthier growth and fruit production.
