Red Flowered Broad Beans. I was lucky enough to be able to take some of the Heligan saved seed home with me this year and the plants are looking really healthy. Judging by the amount of flowers, I'd say it was going to be a fairly prolific cropper. Plants are slightly shorter than other varieties, reaching about 3 feet tall. I sowed these seeds on March 16th, in order that they follow on from the autumn sown Aquadulce Claudia.
