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: Hogweed

Wildflower of the Week is back on the blog with Hogweed, that has taken over from Cow Parsley as the dominant large wildflower of our hedgerows and road verges. Both are umbellifers, with white, umbrella-shaped flower heads, but Hogweed’s flowers are a creamier shade, sometimes tinged with pink, and the whole plant is sturdier.

Cow Parsley (left) is a much more delicate plant with frothy pure white flowers; Hogweed (right) has creamier flowers and is a much sturdier plant.

Hogweed, also known as Cow Parsnip or Eltrot, is a biennial or perennial plant and grows to 2m high. The shoots and flower buds are covered in a leafy sheath when they emerge, opening to reveal a rosette of large, divided hairy leaves.

The flowers are carried on hollow hairy stems. They are rich in nectar and pollinated by insects. They have a rather unpleasant “farmyards” smell, possibly a reason for the hogweed name. The outer petals of the flower cluster tend to be larger. The flowers are followed by flat disc-shaped seeds.

The plant has been used in folk medicine as a sedative and an expectorant … in parts of Eastern Europe it was also traditionally used to treat gynaecological and fertility problems and impotence. Foragers pick the young shoots to cook as a vegetable, reporting it to be tasty and rich in minerals. The dried seeds can be used as a flavouring said to resemble that of cardamon. All however advise extreme caution for a a couple of reasons. First of all the young shoots are hard to identify when the leaves are not fully open so it is easy to confuse the plant with similar looking and extremely poisonous members of the same plant family. Secondly, hogweed sap contains chemicals called furanocoumarins. If you get these chemicals on the skin it becomes highly sensitive to UV light and develops blisters that may leave severe scarring. Foragers advise the use of gloves when collecting hogweed. People using a strimmer to cut down hogweed have reported getting the rash of blisters even through clothing and appear to have been sprayed with the sap. Scything (using a well-sharpened blade) is seen as safer, producing a cleaner cut rather than pulverising the stems.

Cases of skin blistering around the mouth have been reported in children using the hollow stems as pea shooters – to be discouraged!

The hogweed’s big brother, the non-native Giant Hogweed, which grows to 5m, has higher concentrations of the irritant chemicals and should be avoided at all costs. Classified as an “invasive alien’ under the WildLife and Countryside Act, it is an offence to cause Giant Hogweed to grow in the wild – landowners may be compelled to remove it from infested areas or face penalties.

This all makes me rather relieved that our area is populated by the smaller, native version!

Is your neighbourhood troubled by any invasive species?

NB Always follow these guidelines when foraging

  • 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

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

Wildflower of the week: White Dead-Nettle

Commonly seen on road verges and on disturbed land, the white dead-nettle resembles the stinging nettle, but, as its name suggests, has no sting. It is a short to medium height perennial. The leaves (closely resembling those of its stinging relative) are heavily veined, toothed, slightly hairy and heart-shaped, arranged in pairs on square, often reddish stems.

The flowers form in whorls round the stems immediately above each pair of leaves. They are lipped and white, slightly tinged with green. A rich source of nectar, the flowers are popular with insects, especially bumblebees. The blooms have evolved to be pollinated by the larger bees – only they have a long enough proboscis to reach the base of the flower where the nectar is and they are the perfect size for their backs to brush against the stamens and stigma of the flower, depositing and collecting pollen as they feed. The nectar is protected by a ring of hairs that stop smaller insects crawling inside, though some reach the nectar by cheating: they bite a hole in the base of the flower!

As the flowers die the calyx of each remains, forming a spiky cup that holds the developing seed.

White dead-nettle’s popularity with bees gave it one of its old names, the bee nettle. It is also known as white archangel as it was said to come into flower around the feast day of Michael the Archangel. From a certain angle the stamens resemble two human figures and this gave rise to the name Adam-and-Eve-in-the-bower.

The flowers and young shoots can be used in salads or the leaves cooked as a vegetable. Traditional medicinal uses for the plant were for staunching wounds, curing haemorrhage, reducing excessive menstrual bleeding, and also as a tonic to lift the spirits.

White dead-nettle has been in bloom since March and will continue until Autumn

Wildflower of the Week: Crosswort

Crosswort: Cruciata laevipes

Crosswort is one of those wildflowers that seems insignificant at first, but once you spot it, it seems to be growing profusely everywhere. There is a good show at the moment along the grass verges, but as the grass and larger plant grow rapidly they obscure it.

Crosswort is a low growing perennial, that forms rhizomes, underground stems from which the shoots sprout around 4-8 inches high in Spring. The stems are square and unbranched, bearing triangular leaves, both stems and leaves are covered in tiny hairs.

The leaves are arranged in groups of four in a cross-shape, which can be easily seen when viewed from above. This gives rise to the name. It is also known as smooth bedstraw, maywort and maiden’s hair.

The tiny four-petalled yellow flowers also follow a cross shape and smell faintly of honey. They are arranged in clusters around the stem above each group of leaves.

Crosswort isn’t used as a modern culinary or medicinal herb but in the past it was used to treat dropsy, rheumatism and rupture. It was also used to promote would healing and cure headaches. A red dye was extracted from the roots.

Crosswort is found throughout Europe and Asia. In the UK it is less common in Northern Scotland and the far west. It thrives on chalky soils in grassland and roadside verges.

Wildflower of the Week: Garlic Mustard

In Spring, tall upright stems with neatly spaced leaves, topped with small clusters of white flowers, appear in the shade of hedgerows, giving this plant its other common names: hedge mustard or jack-by-the-hedge.

The plant is a biennial, taking two years to complete its life cycle. In its first, non-flowering year the plant forms a low growing cluster of heart-shaped, leaves, heavily veined with serrated edges. In the following year a single upright stem grows up to about 3 feet tall from this base. The leaves become more pointed and almost triangular in shape and are spaced alternately on the unbranched stem. They are a bright, almost lime-green colour, which really makes them show up a in shady areas (where they are growing in sunnier spots the leaves turn a darker green).

The flowers are tiny, each one with four white petals, arranged in a cross shape. The flower clusters form at the top of the stems and are followed by long seedpods.

Garlic mustard is native to Europe, Asia and parts of North Africa. Here in the UK it is an important food plant for both the orange tip and green-veined white butterflies, which lay their eggs on the plants and the caterpillars feed on the leaves. Introduced to the USA long ago, probably by early settlers for food the plant has become a serious invasive weed in some areas, with no natural predators to keep it in check.

Garlic mustard totally unrelated to garlic (it is a member of the cabbage family. The leaves do smell faintly of garlic when crushed and have a mild garlic flavour. Interestingly, Some people report an unpleasant bitter aftertaste, completely undetected by others. For those who do like the flavour, the young leaves can be chopped and added to salads and used instead of mint to make an alternative sauce to serve with lamb. Historically it was used to make a sauce to accompany sea fish – this gives another old name: sauce-alone. The seeds are mildly peppery and can be used as a mild alternative to commercial mustard.

Herbal and folk medicine has employed garlic mustard to treat asthma and other lung complaints and as an antiseptic. As with all foraged wild plants, it is important to follow some common sense safety 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

One of my favourite sights on a sunny Spring day is to see the shoots of garlic mustard standing to attention in front of a hedge or on a woodland edge, with a pair of orange-tip butterflies fluttering overhead.

Wildflower of the week: Dandelion

The grass verges are scattered with the shaggy mops of bright yellow dandelion flowers right now. That’s not such great news for gardeners. They are perennials that will grow back every year. The plants have long tap roots, that are difficult to dig out and can regrow from any fragments left behind. If that wasn’t enough, they are also great at dispersing their seeds, which will grow just about anywhere. But there is a lot more to the humble dandelion than meets the eye.

The deep tap roots will root in the tightest spots, like here between concrete and fence.

Although listed as a single species, there are actually over 200 hundred micro-species of dandelion, virtually indistinguishable from each other apart from being genetically distinct. The plants form a rosette of heavily toothed leaves – which gives them their name (dents-de-lion: lion’s teeth). The familiar flowers are carried on fleshy stems filled with with white sap. The flowers appear from early spring right through summer, and provide a source of nectar for insects, including bumble bees and butterflies, which is especially welcome early in the year when little else is in flower.

Flowers are followed by the fluffy round clusters of seeds (dandelion “clocks”), which are just starting to appear now. Each seed has a fluffy “parachute” attached, which carries it away on the wind. As children, we always used to pick the heads and blow away the seeds – it was supposed to act as a clock – the number of breaths it took to blow away all the seeds would match the time (allegedly)! Some believe that if all the seeds are easily blown away then you will have true love; if some stick behind then your lover has some doubts and reservations!

I was also told recently that children were once warned not to pick dandelions or they would wet the bed! This could have been parental scare tactics to avoid messy sap-stained little hands, although this may come from past use in folk medicine as a diuretic . That gives rise to some of the other old names for the dandelion: piss-en-lit and tiddle-beds. The sap is a folk remedy for warts, though it can irritate the skin too.. Traditionally it had many other culinary and medicinal uses, I’ve never eaten them myself, but the leaves are said to have a bitter flavour becoming stronger with age. Some people use fresh young greens in salads, pasta fillings, pesto and many other dishes. The dried roots have been used as a coffee substitute. Dandelions are also used to make country wines and still used commercially to make the dandelion and burdock soft drink. I’ve only ever fed them to childhood pet rabbits and guinea pigs! Fashionable as foraging is, it’s important to stay safe, use common sense. and respect the countryside.

Do you know any other old names, folklore or uses of the dandelion? I’d love to hear about them.
