Monica Johnson and Brigid Campbell look at
the ever-changing flora and fauna in our beautiful wildflower meadow which
is named in memory of Reg Smith, founder of the Hawk Conservancy Trust.
More Funny Flowers - Reg’s Meadow in July
Meadow Grasses
Pond poppies
Black bindweed
The vegetation in the meadow has grown dramatically during the last few weeks as the grasses have come into full flower, dwarfing many of the smaller plants in their race to set their seed and outdo each other for next year. In the dry pond the vegetation is so thick that many of the smaller flowers can no longer be seen, but the Field Poppies have come out in all their glory, with an impressive display of red. Before the pond vegetation grew so high we found one more new species for our list. This is Black Bindweed, a little climbing plant with spear-shaped leaves and tiny pink flowers, which often grows on disturbed ground.
This month we are taking a closer look at the different grasses found in our meadow. You may think that grass is…....well, just grass and rather boring, but we hope to change your mind!
Funny Flowers 2 - Grasses
Think of a meadow, a field, a hillside, a roadside, underfoot in a wood, a garden or a park in summer, and you think of grass. But the green carpet on your lawn is only part of the story of grass: the bottom bit, without the business end, just a few leaves cut off low before the grass can do what it needs to do to reproduce. That means flowering and setting seed, for grasses are true flowering plants. Like the trees we looked at a couple of months ago, grasses have flowers that don’t look like our idea of a flower at all. So what does a grass flower look like?

Grass Seed Sizes
The first thing to say is that the flower heads of grasses look just as variable as any other group of flowering plants. If you doubt it, just look at the huge variety shown in these photographs of some of the grasses in Reg’s Meadow. The lower picture on the right shows the comparative sizes of some of the different flower heads, to give you an idea of how much variation there is in size alone. But there are some common features, and unfortunately we need to get into some fairly heavy jargon straight away.

Flowers
The heart of every grass flower is the same as all other flowers. First, there are the male organs – stamens, producing anthers with pollen in the form of coloured dust, which causes the summer epidemic of hay fever. Then there’s the female ovary with its lurking ovule, waiting to develop into a seed when the flower is fertilised. Grasses depend mainly on the wind to pollinate them, rather than insects, which is why they produce such clouds of pollen.

Rye Grass
Cocksfoot
Quaking Grass
Each tiny flower is enclosed in small, scale-like bracts called glumes and lemmas, and several flowers cluster together into a spikelet. Spikelets may sit straight onto the stem of the grass: all the way round like a cat’s tail, as in Timothy grass, or in rows up the sides as in the Rye-grasses. They may grow on stalks, in which case the whole flowering head is called a panicle.
Wild Oat
There they may be in big clumps, like Cocks-foot grass, or dangling daintily, each on their own stalk, like the pretty Quaking grass. Sometimes the flowers have bristles called awns sticking out of the end of them, which can make the spikelets look like a paintbrush that has been dipped in water – Wild Oat and the Bromes have especially long awns.
You can identify grasses by looking at the shape of the flower heads, the way in which they grow on the stem, and whether or not they have awns.
Grasses also have ligules, which are thin, whitish membranes found where the leaf sheath joins the stem.
Ligules
Wood False-brome
These vary a lot in shape and can help to distinguish between species that may have similar flowers. The ligules shown here are those of Timothy Grass (left), Cocksfoot (centre) and Yorkshire Fog (right). Some grasses have rough or hairy stems and leaves, while others are smooth and shiny. Wood False-brome, which grows in the corner of the hedgerow just where you turn left for the meadow seating area, has very hairy nodes on the stem, which is otherwise quite smooth – a grass with hairy knees!
Yorkshire Fog
Quaking Grass
Meadow Grass
We think of grass as green, but this is not always the case. Yorkshire Fog is sometimes a deep purple colour when in bud, opening to a pale lilac. Quaking Grass flowers vary from pinkish-purple to creamy white and the delicate Meadow Grass flowers are sometimes so pale that they appear almost white.
Identifying grasses is really difficult, and on this page we’ve only illustrated some of the more distinctive-looking grasses in the meadow. To be sure about many grasses you need a microscope and a lot more expertise than we can muster!
Wheat
Worldwide, grasses are probably the most economically important group of plants to humans. As food plants, they have been domesticated and improved by selective breeding for thousands of years. Wheat, barley, oats, rye, rice, maize, sugar cane – they are all grasses. There are several stems of Wheat in the dry pond, germinated from seeds remaining from the meadow’s previous use as a crop field. We use straw from cereal crops, reeds and bamboo for building materials, hay for bedding of people and food for animals. Civilisation would have been impossible without grasses, and we certainly cannot live without them now.
Featured Flower –Self-Heal (Prunella vulgaris)
Selfheal
Self-Heal is a small, herbaceous perennial of the mint (or labiate) family, growing in grassland, woodland and waste places and found in temperate regions right across the world. It is quite common on garden lawns, flowering as a very low-growing plant when grass is not cut too short, but it can grow to over 30cm in rough grassland, with flowers from June till September or October. It has leaves in opposite, alternate pairs and a cylindrical spike of blueish-purple flowers. Bees are its main pollinators, reaching down into the flower with long tongues to reach the nectar and picking up pollen at the same time. A ring of hairs prevents small insects from reaching the nectar. The flower shape resembles a hook, giving rise to one of the alternative names, “Hook Herb”.
Other alternative names include All-Heal, Slough-Heal, Brunella, Heart of the Earth, Blue Curls, Woundwort and Hercules All-Heal. The generic name Prunella is thought to come from Brunella, the Latin word for “tonsillitis”, or from the German bräune, meaning “quinsy” (in the old “Doctrine of Signatures” it was believed that the shape of a plant indicated which part of the body it would heal – Self-Heal was thought to be throat-shaped and therefore good for treating diseases of the throat, probably giving rise to the generic name). The specific name vulgaris means “common” and the name “Self-Heal” indicates that a sick or wounded person could cure himself by using the plant.
In folklore Self-Heal was highly esteemed, proclaimed a holy herb and believed to have been sent by God to cure all human and animal ailments. The Native Americans made a tea from the roots, to be drunk before hunting, in order to sharpen their powers of observation. The plant has also been used as a vegetable and in soups, salads and stews.
There have been many medicinal uses, in virtually every continent of the world, for all kinds of ailments. In Chinese medicine it is used for liver disorders, conjunctivitis and swollen neck glands. In Europe and other parts of the world it has been used in various ways to treat fever, diarrhoea, sore mouth and throat, internal bleeding, piles, weakness of liver and heart, styes, wounds and bruising. Modern clinical analysis shows that it has good antiseptic, antibacterial and astringent properties, is effective in treating hard-to-heal wounds and is showing promise in research into treatments for Aids, cancer, diabetes and high blood pressure.
Self-Heal is a modest little plant, but one with a healing reputation built up over many centuries which is still proving valid today.
