A large display of over 3,500 wallflowers were planted out last week at the Royal Horticultural Society Garden Wisley for the RHS People's Choice award which will showcase the different forms of Erysimum available on the market to visitors.

Every year the RHS and members of the HTA’s Seasonal Plants Group, organise a People’s Choice Award at RHS Garden Wisley. The spring 2015 plant is the Wallflower, and a number of HTA members submitted large quantities of plants and seeds to the RHS to germinate and grow on and plant.

One of the varieties in the trial is Ball Colegrave’s Sugar Rush series, the first dual-purpose, hardy scented Wallflower which is not just a traditional spring flowering Erysimum, but also is autumn flowering, meaning visitors to the RHS gardens can enjoy both the autumn colour and a repeat flush of colour in the spring. Other cultivars in the trial include Floranova’s Treasure series, A L Tozers Sunset series, and many others from companies including Moles Seeds, Kernock Plants, Syngenta and Binstead Nurseries.

Mark Heath, Trials Development Manager at the RHS, explains: “During recent years Wallflower breeders have been active in breeding new cultivars which flower in the autumn as well as spring, and also Erysimums that flower earlier in the spring after planting out in the autumn.

“The cultivars were supplied as seed, young plants or ready to plant marketable plants by seed breeders, plug raisers and grower members of the HTA.  In spring 2015, when the Erysimum start to bloom, visitors to the gardens will be encouraged to vote for their favourite.”

Voting will close in May 2015 with the overall winner receiving a certificate and gift to mark their success. The public will have more than 50 different varieties of Erysimum to choose from during the popular poll.
