Amazing August wildflowers

This riot of colour is bloomin' marvellous this month.

Each summer the meadows and pathways at WWT Arundel Wetland centre explode with a riot of colour, peaking in August.

Wetland wildflowers blooms provide bees, butterflies and other pollinators with food while their root systems extend deep into the soil, storing water and nutrients while holding on to carbon that would otherwise be released into the air.

A huge variety of wetland plant flower at WWT Arundel each summer - in every colour on the palette. As well as being beautiful many were used traditionally as food, medicine or around the medieval home.

Yellows: fleabane, tansy, ragwort

Ragwort’s ragged looking yellow flowers are a source of nectar and pollen to 150 insect species. It has a bad reputation because the plant is poisonous to grazing animals. Cattle and horses avoid eating fresh ragwort but the danger comes if the dried plants end up in their hay. The yellow and black caterpillars of the cinnabar moth enjoy munching away the leaves, absorbing ragwort’s toxic chemical defence so they become nasty tasting to the birds.

The tight heads of Tansy flower in large clusters on tall plants along the paths and in the meadows in August. Tansy can often be found in herb gardens, as it was traditionally used to flavour eggs. The name ‘tansy’ comes from the old word for an herb-flavoured omelette! For centuries, tansy tea was prescribed by herbalists to expel worms because it is highly toxic to internal parasites. In the veg garden, it is said to drive off potato beetles while attracting bees.

Fleabane is a tall plant with large 30mm flowerheads with an even, yellow fringe. They are a type of daisy and the blooms peak mid-August. Traditionally fleabane’s leaves were dried and burned to give off a vapour to drive fleas and other insects away. English herbalist Nicholas Culpeper mentions its use as an insecticide in the 17 th Century. It was also used as a medicine against dysentery.

Pinks: willow herb, hemp agrimony

It has hairy leaves; a hairy stem and has hairy seeds that ore blown about by the wind! Its flowers are bright pink with creamy white centres. Rosebay willowherb has bright pink flowers grow from a tall spike. Both willowherbs are food plants for elephant hawkmoth caterpillars.

Hemp Agrimony has dense clusters of small, fluffy, pink flower heads are arranged in pairs on reddish stems. They flower July through September in damp or dry spots, in sun or ·in shade. This plant is food for many insects including red admiral butterflies and small tortoiseshell butterflies. Hemp Agrimony was described as a ‘rough medicine’, due to the violent effects of the herb.

Marsh woundwort and purple loosestrife

Purple loosestrife attracts butterflies such as the peacock and small tortoiseshell. It is non-toxic and was traditionally used for the control of dysentery, diarrhoea and fevers. Butterflies love nectar-rich purple loosestrife spikes, especially commas and small tortoiseshells.

With self-heal the clue is in the name. Medieval farmers using sickles and bill hooks and traditional herbalists believed them to help stop bleeding, although this has no scientific basis.
