Wildflower Of The Week: Dog Rose

The blossom in the hedgerow shrubs has changed through the seasons, from blackthorn to hawthorn and now to elder and the beautiful dog rose, which blooms throughout June and July. Our dog roses are actually a collection of several virtually indistinguishable species. The large flowers, up to about 50mm across, are white or pink, with golden yellow stamens. They have a mild sweet fragrance.

The leaves are toothed and arranged in two or three pairs along thorny stems. The shrub is straggly and grows to 3m or more if well-supported by surrounding hedge plants.

The roots are used in the horticultural industry in the propagation of garden roses. Shoots of the cultivated varieties are grafted on to dog rose root stocks.

The flowers are followed by oval orange-red fruits or hips. These are rich in vitamin C and can be used to make a tea or syrup. As well as a vitamin source, the syrup has also been used to treat gout, dysentery and as a diuretic. The irritant hairs on hips have been used to make itching powder. The roots were used in folk medicine to cure rabies. The flowers are used in skin preparations.

The flower, or at least a stylised version of it is a common feature in heraldry, often seen on coats of arms. Also known as sweet briar, the rose has symbolised love and beauty for millennia. In Ancient Greece the dog rose was often associated with the Goddess of Love, Aphrodite, who was depicted as wearing a rose crown. The Romans bestowed an association between the dog rose and secrets. Anything said under places where roses were hung, would remain secret, giving rise the the phrase “Sub rosa”.

Occasionally reddish fibrous tangles appear on the stems of dog roses. These are known as Robin’s pincushions. and are caused by a tiny gall wasp laying eggs in in the stem. The gall shelters larvae of the wasp, which feed on the gall over winter to emerge as adult wasps in spring.

The dog roses I see in the hedgerows are a sign that summer is most definitely here!.

Wildflower of the Week: Red campion.

It’s impossible to miss the tall clumps of pink-red flowers of red campion that are growing in profusion in hedgerows and woods at the moment and will continue to do so until August and well into Autumn and Winter if the weather is mild. This relative of the carnation is a short-lived perennial that produces copious seed that enables it to spread rapidly , especially in fertile soils.

The plant grows up to a metre tall, though usually 30-60cm high. with leaves and stems covered in softly downy hairs. The leaves are pointed oval in shape, carried in pairs on the stems.

The flowers carried in small groups at the end of the stems. Each has five petals and each petal has a central cleft. the calyx immediately behind the flower is dark red/brown and hairy. The plant is dioecious, that is a single plant carries flowers with either female or male parts, not both as in most flower species. On the female plants the calyx develops into a vase-shaped seed capsule full of tiny black seeds. The female flower produces a sticky substance that causes pollen from visiting insects to stick. The Latin name for the campion family, Silene, may come from the woodland god Silenus or from the word for saliva.

The red campion hybridises freely with the closely related white campion with resulting flowers in a wide range of shades of pink. Though I’ve never noticed this, you may come across flowers with a darker centre. This is caused by a fungal disease known as anther smut, producing dark spores on the reproductive parts of the plant

The plant is sometimes called the Adder Flower from it’s use in folk medicine to treat snakebites (though personally if I was in this situation I would prefer to seek professional medical advice immediately rather than take my chances with the plant!) The roots of plants in the campion family can be used to prepare a soap substitute, though the red campion is less known for this than it’s close relative, soapwort. The 16th Century herbalist, John Gerard said that the hairy stems could be used to make candle wicks. A century later, Nicholas Culpepper described a number of medical uses including the treatment of kidney stones and internal bleeding as well as to “helpeth those that are stung by scorpions or other venomous beasts”.

Another country name is Batchelor’s Buttons as unmarried young men would wear the flower in a buttonhole..

Red campion certainly provides a welcome splash of colour in late spring and throughout the summer.

As always, please remember these guidelines.

  • Don’t touch or pick any plant unless you are ABSOLUTELY CERTAIN that it is safe to use, and not poisonous.
  • Don’t pick anything unless it is abundant
  • Only pick small amounts and no more than you need
  • Don’t pick if there is a risk of pesticide/weedkiller or other contamination, including from traffic or other forms of pollution.
  • Always get permission from the landowner.
  • Avoid areas which may be soiled by animals (wild or farm animals or pets)
  • Wash plants thoroughly
