Wildflowers

'Wildflowers' is a popular name used by many field-guides to encompass flowering herbaceous species.

'Trees, Shrubs & Climbers', 'Grasses, Sedges & Rushes', 'Ferns & Horsetails', 'Mosses' and 'Liverworts' can be found in separate species Galleries.

See our Recording Trees, Wildflowers & Grasses page for useful guidance on what to record.

More on recording in Leicestershire and Rutland and contacts for our County Recorders are on the webpage of our local VC55 branch of the BSBI.

Clive Stace’s ‘New Flora of the British Isles' - 4th edition (C&M Floristics, 2019) is the standard reference book that NatureSpot uses for verifying records.

Useful websites and publications

Facebook Group: Wildflowers of Britain & Ireland

British Wild Flowers - an enthusiast's photo site. Comprehensive photo library but only one species at a time.

BSBI Plant Identification - lots of resources for helping you to identify that plant!

We recommend that you look at the 'Get Started' advice on the BSBI's website, which includes Andrew Branson's useful reviews of some popular field guides.

The botanist’s bible is Clive Stace’s ‘New Flora of the British Isles' - 4th edition (C&M Floristics, 2019). Not for the faint-hearted, but it does include keys for the identification of all native, naturalised and crop plants in the British Isles, and is the standard reference book that NatureSpot uses for verifying records.

To help identify plants that are not in flower, many botanists use John Poland and Eric Clement's 'The Vegetative Key to the British Flora' - 2nd edition (BSBI, 2020).

The BSBI also publish a set of Handbooks on difficult plant groups, with detailed keys, descriptions and line drawings (for example, sedges, umbellifers, willows and poplars, grasses, pondweeds). These are excellent publications. There is also their Plant Crib guidance, with many useful tips for more difficult species.

Specific ID resources may be found under each section, family or species in the galleries.
