In England at this time of year, the hedgerows along country lanes are full of delicious fruits called blackberries. Just last week I spent an enjoyable afternoon with friends gorging on blackberries along the route of an old railway line in Norwich (now a footpath and cycleway). The berries are a good source of vitamin C and antioxidants, and are commonly used in desserts and preserves. Although I love collecting and eating blackberries, I have a bit of a love-hate relationship with the plant that produces them, the bramble (Rubus fruticosus agg.).
Rubus fruticosus agg. isn’t a single species, but instead is a group (or aggregate; agg) of around 200-300 very similar species of shrub in the rose family that are very hard to tell apart (1). Like roses, brambles are covered in sharp thorns that help to protect the plant from herbivores (and humans). The thorns also help to make brambles a safe haven for many small birds and other wildlife.
Brambles grow wild across most of Europe and in the UK they can thrive in most environments (1). The white or pinkish flowers are self-fertile and can still produce seeds even in the absence of fertilization (a process called apomixis) to produce an army of clone plants (2). Furthermore, brambles can produce suckers – new shoots from buds in the roots – which helps them rapidly cover an area of ground. As a result, brambles are often among the first plants to colonise abandoned plots of land. This is great for wildlife and the casual blackberry picker, but it’s not so helpful if you are trying to work on said piece of abandoned land…
When some friends and I took on an allotment this year, our plot had been neglected for a while and contained quite a lot of brambles. We removed a lot of the plants but have left some to be our own personal blackberry patch. Removing brambles is not a fun business as the thorns can cut through clothes (and gardening gloves). For several weeks in the spring my arms and legs were covered in scratches and I often found bramble thorns impaled in my fingers. If you don’t manage to completely remove the whole root, the bramble is quite capable of growing a fresh shoot so we’ve had a few cheeky brambles reappearing in the vegetable beds.
Despite my moaning about brambles I must say that the blackberry crop from the allotment has been great. It is kind of ironic that our most successful crop this year is something we weren’t deliberately growing. All in all, if I had to summarize my relationship with the bramble at the moment, I would say: “it’s complicated”.
