Erysimums, or ‘Wallflowers’, can be annuals, biennials or woody-based perennials. Our favourite for this month are the perennial types with their long lasting flowers in shades of mauve, apricot, yellow and red.

Growth is best in a sunny spot with good drainage. They are often grown successfully in loose wall mortar, hence the vernacular name, ‘wallflower’.

The flowers, appearing in spring, usually have a strong fragrance and are often associated in spring bedding schemes with tulips and forget-me-nots.

• Prefers a sunny spot with a well-drained soil
• Trim lightly after flowering to prevent plants becoming leggy
• Good for attracting a wide range of beneficial insects
