Wisley Magic is a heritage variety red flowered runner bean which is often considered one of the best for flavour and having that “old fashioned runner bean taste”.
However, having grown several varieties of runner bean at one go I’m not sure there is much difference between them. Having said that, Wisley Magic does have some distinct advantages. It holds an RHS Award of Garden Merit at the time of writing, it is virtually stingless, even when mature and their long, slender and straight pods helped me win best set of runner beans at this years allotment show.
Sow indoors about 2-3 weeks before the last frost is due. Plant out once they are up and all risk of frost has passed. You will need to support these using a wigwam, trellis or bean frame as these will go over 6ft. Once they start cropping, pick at least every other day to keep the beans coming.
In the Kitchen: Pleasantly flavoured and all except the oldest of beans are stingless.
Plant health and Yield: As with all runners, these can produce bumper crops. and the beans are attractive, long, slender and generally quite straight, although if you are a showing enthusiast or trying to grow the longest bean you probably should look elsewhere. In the hottest of temperatures, like with many runners some flowers will drop without forming beans. making sure that your bean trench has plenty of organic matter in and is well watered will help.
