Buying wall flowers can be confusing because they come as annual, biennial and evergreen perennials. Those illustrated above are the biennial/short-lived perennial varieties which are best for scent. This means when selecting Wallflowers for scent, pick carefully the biennial varieties which do have a strong scent and make a really good spring bedding plant.
A highly scented Wallflowers are the E. cheiri group, which blooms yellow and orange, such as E. cheiri ' Fire King', 'Primrose Dame'. E. 'Sugar rush' is dark red and scented, and ' Sugar rush orange'.
If you are selecting wallflowers looking for border colour and longevity, choose one of the perennial varieties. The image below left is of E. Bowles's Mauve, which is a popular, widely grown perennial variety of Wallflower, ideal for the borders and long flowering, but not scented. E. Bowles's Mauve will flower all year as will 'Winter Orchid'. These are perennial plants suitable for permanent planting in the border compared with the biennial types, which are excellent for spring bedding.
Wallflowers look fabulous with tulips if planted with a late flowering type, so they will bloom together. Many on-line retailers and garden centres sell tulips and wallflowers which will flower together for a planting scheme. They also look good with forget-me-nots, another spring biennial.
