‘Sugar Rush’ wallflowers

Erysimum cheiri ‘Sugar Rush’ is a wallflower and hence part of the Brassicaceae family alongside plants like cabbages and mustard. You can see it all over town at the moment.

The Parks team sowed these plants in their nursery in July ready to be planted out as part of their winter bedding schemes. The gardeners are now planting all 2,500 of the finished plants out – a big job in anyone’s book! This is a British-developed wallflower strain that grows to around 25cm tall and will flower from now until April, with perhaps a small break in December. The flowers are even slightly fragrant. The plant is available in many colours, including reds, yellows, oranges and purples.  

It is ideal for full sun or partial shade, and although hardy it will do best with a little shelter. The soil should be moist but free-draining. They can be grown in pots or containers as well as borders. Wallflowers can occasionally suffer from mould; you can help keep this under control by removing diseased leaves. Sugar Rush works well as part of a bedding display and is a great companion to other winter bedding and bulbs like pansies, polyanthus, hyacinths and tulips, as a look at the Parks team’s numerous displays around the University will show. Propagate from seed in summer; more information is available online.
