Ireland has a diverse and astonishing collection of native wildflowers. For ease of identification, the species are divided into colour categories and within each category the species are grouped by, for example, the number of petals in the flower or whether the species carries its flowers in a cluster or a spike.

In easily understood terminology, focus is put on the main identifying features of each plant, by colour, size, shape of flower, leaf, habitat, flowering season, and where in Ireland it might be found.
