With all the talk about the collapse of our bee populations and the decline in the number and variety of our native butterflies, gardeners can do their bit by providing the flowers that can help to support butterflies, moths, bees and hoverflies as they journey around our gardens looking for a pollen and nectar fix.
Some years ago, the RHS developed lists of plants called ‘Perfect for Pollinators.’ The two lists are for cultivated plants and wild plants across the seasons. Check out http://www.rhs.org.uk for more details and the lists.
Over the last century, gardeners, growers and breeders have concentrated some of their efforts on developing and using double flowers to increase the effect of the display and this, alongside many other factors, has not helped us to support our pollinating insects because the pollen and nectar are hidden deep in the flowers, making them inaccessible to the insects.
The ‘Perfect for Pollinators’ lists contain, for the most part, wild species of plants whose flowers are simple, single and easily accessible. Comb through your latest Thompson & Morgan seed and plant catalogues and compare them with the ‘Perfect for Pollinators’ lists. It will not take you long to find some stunning plants for your garden that will not only give you a lot of pleasure, but will help to support some of our vital flying insects as well – everyone is a winner!
The new Rudbeckia collection, with three fabulous cultivars that will flower from July until October, with their simple, flat, open daisy-like flowers are a perfect example of a flower design that suits all of our pollinating insects. The new yellow Cosmos ‘Xanthos’ is another excellent example to search out.
Plants that have lots of very small flowers in clusters, such as the new Ageratum ‘Pincushion Mixed’, that will flower from June to September, are perfect examples of plants that will provide that quick nectar fix that butterflies and moths need to give them the energy to search out a mate – an essential part of maintaining their populations! The 2016 catalogue contains a number of different strains of Foxgloves and I feel sure that we have all seen bumblebees struggling to clamber into one of those inviting trumpets to get their daily pollen supply and a nectar fix for energy.
Many of our hardy annuals (HA in the catalogue), that can be sown directly into the garden in April and May, will provide hundreds of nectar and pollen rich flowers from June right up to the first frosts of autumn. Some can even be sown in September and October, lasting the winter as young plants and flowering in April, May and June. Examples to look out for include the new Nigella ‘Midnight’, Amberboa muricata, Ammi visnaga, Bupleurum ‘Green Gold’, Calendulas, Californian Poppies, Cornflowers, Cosmos and Daucus ‘Dara’ .
I will leave you to go through the rest of the catalogue yourself to discover the many other wonderful examples of plants that can provide that essential support for our butterflies, moths, bees and hoverflies. Remember that 30% of all that we eat is reliant on pollinating insects – apples, pears, plums, blackcurrants, blueberries and runner beans, to name but a few.
