Benefits of Wildflowers for wet areas

In February we wrote an article about growing wildflowers on clay. Clay soils often get very water logged in winter but what about areas prone to regular winter flooding that remain under water for long periods. Flood meadows have always played a part in flood alleviation and there are many benefits of growing specialist wildflowers for wet areas. As a scheme at Longford near Gloucester demonstrates, the  restoration and creation of new wildflower water meadows can naturally enhance  flood defense schemes as well as providing a valuable asset for the community and a haven for wildlife.

Creation of Plock Court Wetland Area

In spring 2011 we were asked to supply a wildflower mix for an area, just north of Gloucester, on the edge of the River Severn’s flood plain. The area is just a few hundred metres from my own home and working with Gloucestershire City Council,  I surveyed the area in early spring 2011. The site was previously used for sporting activities and prone to very regular winter flooding. The Northern half of the site, an area of just under 1 acre was the wettest and it was decided that this area would be sown with a special mix of wildflowers for wet soils. The remaining area, similar in size, was not as prone to flooding, so here we decided to use a  clay wildflower mix that would tolerate slightly drier conditions in the summer months.  Additionally it was decided to sow  a special tussocky mix at the edge of the scrapes. This would provide  taller vegetation and more cover for wildlife.

In the summer of 2011 the existing grasses were removed and the whole site prepared for sowing. At the same time, 2 wildlife scrapes were excavated and connected to a nearby ditch by means of a shallow balancing channel.  Surplus water would  then be absorbed by the planned  wetland meadow, acting as a large soakaway and reducing flood risk. When the rainfall subsides excess water in the scrapes could drain gently  back into the ditch.

The area was sown in October 2011 and fortunately the winter weather was kind, allowing an excellent germination. Most unusually, several perennial wildflowers were already in flower the following summer including Ox-eye daisies and Ragged Robin. The area had previously  held a good stands of Cuckoo flowers in the surrounding ditches and these were quick to spread into the newly sown meadow grass. Over the winter the area was planted with new native trees including oak, birch and alder. The whole area was enclosed with an attractive post and rail fence. Some additional wildflower plugs were  planted to provide specialist wildflowers for wet areas around the pools.  At around this time, the wetland area benefited from long term protection, when the playing fields were awarded  “field in trust” status to mark the Queen’s Diamond Jubilee year.

The winter of 2012 was unusually wet with the whole area under water for many weeks in early spring. The sward recovered from the inundation of floodwater extremely well and by the summer of 2013 the whole area was in full flower offering a spectacular sight in the summer sunshine. Ragged Robin, Ox-eye daisy and Meadow Buttercup dominated the display.

In 2014 and 2015 the Ox-eye daisy and Ragged Robin became less dominent but were  replaced by other slower growing species supplied within the original seed mixtures such as Common Sorrel, Meadow Cranesbill, Black Knapweed, Purple loosestrife and Hedge Bedstraw. Some of these can be seen in the short video below.

At the bottom of this article you can find a more comprehensive list of some of the wildflowers that can be seen at Plock Court  Wildlife area in spring and summer. Many of these species make great wildflowers for wet areas and we can supply many of them either as plug plants, bulbs or  wildflower seed packets.

The Plock Court wetland  area has become a haven for wildlife. The scrapes attracted a visiting Green Sandpiper within the first 12 months of construction and also a Little Egret and Snipe. In spring the muddy edges of the pools provide vital nest building material for a nearby colony of House Martins at Plock Court. The surrounding trees and newly planted shrubs are already attracting warblers in summer such as Chiffchaff, Whitethroats, Blackcaps, Sedge and Willow warbler. Now that the vegetation has become established, Dragonflies and Damselflies have become a common sight in summer around the pools.

As time passes it is hoped that more wildflower species will appear in the wetland area, some as a result of the initial sowings and some through natural regeneration. Eventually the whole meadow could resemble how it would have looked in the past. It is likely that vegetation will eventually develop around the scrapes, creating habitats similar  to those at the nearby disused brick pits such as Walham ponds and Sandhurst Nature reserve.

Visiting Plock Court Wildlife Area:

There is a small car park just to the left of the entrance to the sports parks. From here, the  Plock Court Wetland area is about a 2 minute walk. You will find several benches and a picnic table. The best months to find wildflowers are from June to August. It is politely requested that dogs are kept on leads within the sensitive area inside the railed fence.
