Wallflowers are one of the best scented garden plants which are often overlooked, perhaps because of their association with cottage gardens. Wallflowers are available in a host of lovely shades of reds, orange, russet, pinks, apricot, purples many subtle shades and strong colours. The stunning feature of Wallflowers is their amazing scent present throughout their long flowering period from spring to early summer.
Wallflowers are easy to grow and need little more than a sunny spot and soil which is well drained or on the drier side. There are both perennial and biennial varieties, and it is the biennial variety which have the best scent, illustrated in the top three images. The biennial varieties can be treated as bedding and once flowering has finished put it in the compost, although sometimes they are good for another year. The strong red varieties, such as 'Constant Cheer' look great as a contrasting plant combination with lime green Euphorbia.
You can buy Wallflowers, Latin name Erysimum, as bare-rooted cuttings in the Autumn which are inexpensive and plant them out to establish roots and growth over the late Autumn and winter ready for flowering in the spring. They can look a bit weedy when first planted out, but they will get established and usually do very well in the spring. Given that Wallflowers are mainly biennial and short lived, it is more economical to buy them as bare-rooted plants as compared to the fully grown container plants which are generally sold later in the year at garden centres.
If you miss the autumn planting, which I have often done, Wallflowers are available again in the spring as fully grown plants ready for flowering and whilst more expensive, they do make a great fix for colour and scent in containers and borders. Wallflowers are fully hardy.
