Gardening & Environment

The family of grasses, the Poaceae, is the fifth largest, with 12,000 species. Their physical stature varies enormously, from low growing bents on golf greens, to pretty ornamental grasses grown in gardens, to the bamboos and elephant grasses used to feed pandas and burn for energy.

Grasses are also crucial for life. They act as a larger carbon sink than the Amazon rainforest and are used to manage floodwaters, improve soil health and provide erosion control on slopes and roadside verges.

The blogs I write here demonstrate how gardeners and researchers are increasingly using grasses to create amazing gardens, as well as helping to save our planet.

Grass roofs lead way in urban greening

In 50 years time large parts of cities like London will have been ‘greened’ both at street level and on the roof-tops according to urban ecologist Dusty Gedge.

He says that there are multiple benefits of having plants living on top of buildings. In summer they help cool offices and factories reducing the need for air conditioning, and in winter they can offer a certain amount of insulation.

They soak up storm-water – holding heavy rainfall in situ preventing flash flooding at street level; provide insulation against noise which is useful in noisy areas such under a busy flight path, filter air pollution, are lovely to look at and attract wildlife such as birds, butterflies and bugs

Electricity from grass

Green plants like grass could generate electricity according to researchers at Massachusetts Institute of Technology.

It might be some way off before we run our televisions and microwaves off lawn clippings, but within a few years villagers in remote, off-grid locations could start producing enough power to charge cell-phones and lanterns.

“Today the most widely used source of lighting in such locations is kerosene lanterns…

We mustn’t lose our lawns

Last summer Colin Crosbie, curator of the Royal Horticultural Society (RHS) Garden at Wisley, defended lawns in a radio debate, saying he believes having dedicated areas for grass is important for recreational and environmental reasons.

For instance, green spaces are good for mental health and lawns help absorb rainfall so less ends up flooding man-made drains.
