Museum Gardens

Another aspect to the Museum of Berkshire Aviation is its small yet highly diverse wildlife garden. It’s actually a mixture of wild plants with some cultivars donated by the volunteers. Tony tends the garden by retaining a natural ambience. I occasionally help when he needs it but largely he allows the garden to tend itself I give him a hand. There are some nice gems in the garden.

Oriental poppy

Papaver orientale ‘Papillon’

Oriental poppy in early June

 

A perennial flowering plant native to the Caucasus, north-eastern Turkey and northern Iran. Oriental poppies grow on long stems covered profusely with curly leaves that dies away after flowering. This is to allow the plant to survive the summer drought of Central Asia. Fresh leaves appear with autumn rain.

Oriental poppy buds in mid-June

 

Oriental poppies are related to the great scarlet poppy papaver bracteatum, which can be grown for the commercial extraction of thebaine, a main source for the legal synthesis of opiates. Oriental poppies, however, does not produce any narcotic alkaloids such as morphine or codeine.

Common or purple salsify

Tragopogon porrifolius

Cultivated for its ornamental flower, edible root, and herbal properties, Tragopogon porrifolius also occurs in the wild. It is native to Mediterranean regions of Europe but has been introduced into northern parts of Europe, central and southern England, North America, Australia and southern Africa.

Purple salsify in late May

 

The stem grows to about 120cm in height and is usually single stemmed with grass-like leaves. The flower head has sixteen petals in two layers about 5cm in diameter. Under the petals are eight green bracts. The flowers close about midday and don’t open on dull days. The root is used as a vegetable in parts of Europe and Russia. In the UK it was used as a vegetable in the 18th century but has fallen out of popularity.

Common Blue Damselfly

Ebllagma cyathigerum

A highly prolific damselfly occurring around rivers, lakes, marshes and bogs and occurs throughout the British Isles. Incidentally, damselflies can be told apart from dragonflies because they fold their wing at rest whereas dragonflies, hawkers and darters keep their wings open.

Male common blue damsel in late June

 

On the male segment two has a mark of a spot linked to the inter segment suture by a short line. Segments eight and nine are entirely blue.

 

The female occurs in two colour forms, one blue, as in the male, the other dull green. The mark on segment two is thistle shaped and there is a ‘Christmas tree’ shaped stepped triangle on segment eight. They often perch on plant stems.

During mating, the male clasps the female by her neck while she bends her body around to his reproductive organs. It is called a mating wheel but actually forms a charming heart shape. The pair fli together over the water and eggs are laid on a suitable plant, just below the water-line.

 

The eggs hatch and the larvae, called nymphs, live in the water and feed on small aquatic animals. Nymphs climb out of the water up a suitable stem to moult into damselflies.

 

Length: 32mm

Flight Period: April – September/October

Tower rockcress

Arabis turrita

Tower rockcress Arabis turrita late May

 

Tower rock cress is a plant native to the southern half of Europe having erect woody stems. It occurs in Britain but is very rare.

 

It prefers forest edges and clearings in stony or rocky soils. It grows from 45-95cm tall and a small cluster of white flowers of four petals are produced at the top of the stems from April to May.

Teasel

Dipsacus fullonum

Dipsacus are native to Europe, Asia and northern Africa, the most common in Britain is Fuller’s teasel (dipsacus fullonum) which grows to at least 1-2m tall.

 

The ovate seed head is very popular with goldfinches in the autumn and winter and teasels are often grown in gardens and encouraged on some nature reserves to attract them. Teasels are grown as ornamental plants, and the dried heads are used in floristry.

Teasel Dipsacus mid-September

 

The dried flower heads of Fuller’s teasel were attached to spindles, wheels or cylinders providing a natural comb to raise the nap on fabrics especially wool. By the 20th century, teasels had been largely replaced by metal cards, which and do not need to be constantly replaced as the teasel heads wear.

Periwinkle

Vinca major var. oxyloba late May

Periwinkle late May

 

Greater periwinkle is an evergreen perennial plant growing naturally in western Mediterranean countries. It grows up to 25cm tall and spreads indefinitely making it popular for use as ground cover. Its flowers usually have five petals but six petals may also occur but are quite rare.

Red Admiral

Vanessa atalanta

Red admirals are widespread and can be found in almost any habitat from woods, parks, gardens to the seashore and the tops of the highest mountains and anywhere in the British Isles, including Orkney and Shetland. Adults can be seen throughout the year but there is an increase during May and June as migrants arrive from the continent.

Red admirals on buddleia

 

The adults feed on nectar from a number of sources including buddleia, ivy blossom and bramble. They are also partial to rotting fruit such as windfall plums.

Eggs are laid singly on the upper surface of a leaf of the food plant and several eggs are often laid in the same nettle patch. They are light green at first, but turn darker as the larva develops. Eggs hatch in about a week.

 

Wingspans: Male 64-72mm, Femle 70-78mm

Foxglove

Digitalis purpurea

The scientific name digitalis means finger-like referring to the shape of the flower. In the second year the flowers grow from a spike 50-250cm tall and can vary in colour from purple, pink, white or yellow depending on the species.

Foxglove Digitalis purpurea late May

 

The best known species is the biennial digitalis purpurea. Foxgloves prefer acidic soil in partial sunlight to deep shade in open woods moorland margins, sea cliffs, rocky mountain slopes etc.

Downy birch

Betula pubescens

Downy birch is a species of deciduous tree native to northern Europe, northern Asia, Iceland and Greenland. It typically grows to about 20m with a girth of 2m although it can sometimes grow to 27m with a 3m girth. The flowers are catkins pollinated by the wind and are produced in early spring before the leaves come out. The fruit are a pendulous collection of cylindrical shapes 1-4cm long and 5-7mm in diameter. They disintegrates at maturity releasing the individual seeds. They are 2mm long with two small wings along the side.

Downy birch can be confused with the closely related silver birch (betula pendula). The downy birch has a dull grey smooth bark with thin horizontal fissures. The silver birch has a striking white bark with large black random fissures. The leaves are ovate with fine serrated edges whereas the silver birch leaves are more heavily serrated. The downy birch thrives in wet peat bogs but silver birch prefer drier sandy soils.

The downy birch can also be confused with the dwarf birch (betula nana) especially in Iceland where the species sometimes combine to form hybrids. The larva of the autumnal moth (epirrita autumnata) feeds on the foliage of downy birch along with other tree species. In outbreak years, large areas of birch forest can be defoliated by this insect.

Orange-tip butterfly

Anthocharis cardamines

The orange-tip is a sign of spring and is one of the first species emerge that has not overwintered as an adult. The male forewings have orange tips and hence the name but the female lacks this colour feature. Both sexes have a pattern of blotches that appear green but are actually formed by a combination of yellow and black scales. When at rest on a flower head with its wings closed, the orange-tip is very well camouflaged.

The male is generally more active than the female as it flits from plant to plant and may fly for longer periods without rest. The female, being more concerned with egg-laying, and is usually found around food plants. The orange-tip occurs throughout England, Wales and Ireland but is more localised in Scotland. It has a wide range of habitats which include hedgerows, riverbanks, woodland margins, damp meadows and gardens. There is a single brood each year and the eggs are laid singly on separate flower stalks. This is because the larvae are cannibalistic.
