I'm a big fan - and member of - the Cottage Garden Society.
The CGS is a group of about 6,000 friendly and typically experienced gardeners, organized into small regional groups in the UK. Without being preachy they have an underlying philosophy I absolutely empathise with:
Gardens now provide vital habitats for wildlife, as a result of changes in farming methods, increased use of chemicals, destruction of orchards, hedges and ponds. By growing simpler, traditional cottage garden flowers such as lavender, thyme and other herbs, foxgloves, pinks and single varieties of flowers, rather than modern, double-flowered varieties, we can help to maintain a variety of birds, butterflies, insects etc. Modern hybrid flowers are often sterile and produce no nectar for insects, who have an important role in pollinating our fruit and flowers. Bees in particular need gardeners help in providing nectar-rich flowers - bumble bees are especially affected by the loss of food plants, and their numbers have declined. Other beneficial insects, birds, frogs, toads, hedgehogs also contribute to our gardens in helping to keep down insect pests, slugs and snails. By encouraging biodiversity in our gardens, we can help maintain the precarious balance of nature.
This might very well have come from our own website. Membership is from a very reasonable £9, for which you get a range of benefits adding up to a lot of practical help.
