A lot of evergreen plants have flowers, although the plants won’t be in flower all year round. Camellias have beautiful glossy green leaves all year round and in spring produce large colourful flowers. Our favourites are yellow camellias, Camellia ‘Roger Hall’ (red), and Camellia ‘Elegans’ (pink). And Californian lilac, or ceanothus, is covered in clusters of powder blue flowers in spring.
