Gardeners can take simple yet effective steps to protect their favourite plants from disappearing, according to conservation charity Plant Heritage. New research reveals that more than half of historically cultivated plant species in the UK and Ireland are no longer commercially available, while one in six species exists in only one or two known locations or has vanished entirely.
Why Plant Conservation Matters
Saul Walker, partnerships and events manager at Plant Heritage, emphasises that cultivars—plants bred for specific characteristics—are not just for the moment but for perpetuity. He urges gardeners to view their plants as long-term investments rather than fleeting trends. For example, dahlias once fell out of favour and many varieties disappeared, only to become popular again later. With climate change, breeders will focus on resilient plants, but preserving colour diversity remains crucial.
1. Adopt a 'Pick and Mix' Approach
Walker advises against sticking to a single cultivar. Instead, choose a variety of plants to boost biodiversity and resilience. Different cultivars may withstand varying environmental conditions, helping your garden thrive. Even focusing on one genus, like dahlias, can open up a world of variety and lead to conserving rare cultivars.
2. Propagate and Share
Propagating plants and sharing them with neighbours, friends, or at plant sales helps keep varieties alive. Many plants have been saved from the brink of extinction simply by being propagated and distributed among gardeners.
3. Conserve Your Outdoor Space
Resist the trend of paving over gardens. Even small spaces like balconies or courtyards can be used to preserve plants. Think ecologically and let nature take precedence over artificial materials.
4. Understand the Plants You Already Have
If you move house or inherit a garden, don't rush to dig everything up. Use resources like books, apps, gardening societies, and professionals to identify what you have. You might discover rare treasures. Leave the garden for a year to see what emerges in different seasons, then consult National Collection holders via the Plant Heritage website for specifics.
5. Join Plant Heritage
Plant Heritage is the only UK charity dedicated to conserving cultivated garden plants. With local groups, it offers a social element, plant visits, fairs, and flower shows, providing both knowledge and community support for conservation efforts.
