Erysimum, also known as the perennial Wallflower, provides a massive flush of colour from early in the year for a long period.
There is a wide range of flower colour in the warm spectrum, including white, yellow, orange, red, pink, maroon, purple and brown. The flowers, appearing in spring, usually have a strong fragrance. They are very easy to grow and are well suited to the beginner, producing masses of flowers for little effort and are not affected by many pests or diseases.
They are well suited to planting with a range of spring bulbs to provide a mass of colour in spring, but can also be planted with other spring shrubs and perennials.
