Gardening for biodiversity

Which pollinator friendly species should I choose?  

To create a truly diverse garden, try to choose a range of native flowering plants and a few others from Europe or the Northern Hemisphere. The different flowering times, shapes and colours will prolong the flowering season, so you’ll be providing food for early bees, butterflies, moths and hoverflies right through into the autumn.  It also means your garden or windowsill will look lovelier for longer.  

Try to include British native species, as these will be staple sources of nectar and pollen for our insects. Many species will have evolved a co-dependent ‘special relationship’ with one or two of some of our native pollinators. Lady’s smock Cardamine pratensis for example is a high value treat for orange-tip butterflies, often seen in early spring. Lady’s smock is one of the orange-tip caterpillar’s favourites and both the male and female adults drink the nectar from its flowers. Whilst foxgloves Digitalis purpurea and ox-eye daisy Leucanthemum vulgare will provide a feast for a wide range of pollinators. 

Mix up your planting with some flowering plants from Europe and the Northern Hemisphere so you’re making food sources available for as long as possible each year. Pollinators such as queen bumblebees will often emerge very early in the year to look for new nest sites. Others, including ivy bees, can be active quite late into autumn. Plants from elsewhere in the Northern hemisphere should be happy growing in the British climate and they’ll provide your garden with a wide range of colours and flowering times.  

If you’d like some inspiration, we’ve put together some short lists of pollinator-friendly plants for sunny and shady spots which work well together to provide colour and nectar for as long as possible. 

How do I know if a plant is native or not? 

Some of the common plants we see in gardens across the UK actually originate from elsewhere.  The common hollyhock Alcea rosea a classic English country garden plant, was imported to the UK from China around the 15th century. That quintessentially ‘English’ lavender Lavandula angustifolia actually originates from Southern Europe and the Middle East.  Even though it’s not a native, lavender is usually abuzz with bees – so it’s a fantastically pollinator-friendly plant if you can grow it. In fact, with the global rise in temperatures, we may need to start planting more drought-friendly plants from places like the Mediterranean, so our pollinators stay well-fed.  However, more exotic plants, however, such as rainforest species, or those from the Southern hemisphere, are much less likely to attract our pollinators. But don’t rule them out! Nature – and gardening – is all about balance, so include some exotics with wildlife-friendly plants.

A word of caution – some non-native plants can do almost too well in our local climate. The butterfly-bush  Buddleja davidii comes from China and Japan. It appears very pollinator-friendly – it’s usually covered with red admiral butterflies. But it’s very invasive and can overrun a site and elbow out other plants. So the butterflies have a ball, other important pollinators lose the chance to find nectar. But, if you really love your butterfly-bush, there’s no need to chop it down. Just remove the spent flowerheads before they set seed. Or, you could plant hybrid species such as Buddleja weyeriana hybrids which are still attractive to butterflies, but don’t easily spread.
