Most varieties of Cornus are deciduous and will go dormant during Winter before reshooting in Spring as the weather starts to warm up. There are some evergreen varieties and herbaceous perennials. Their foliage is usually broadly lance-shaped where many of the cultivated plants have variegated leaves. They flower in Spring and Summer with small stunning flowers, with the range of colours from pink, red, cream and white.
