A Year of Watercolour walks readers through the creation of beautiful and evocative watercolor scenes including seasonal plants emerging, animal hibernation and migration, speckled eggs in a bird's nest, home-grown vegetables and much more. With a wide array of subjects, Harriet explores the idea of seasonality around the world, whether that's cherry blossoms signalling spring in Japan, the red and brown leaves of autumnal New England, or the summer strawberries of the UK.

Alongside the seasonal tutorials, Harriet includes advice on how to observe and depict nature at close hand - including creating a travel kit for 'painting walks' out in nature, and charting the growth of a plant over the course of a single season.
