D. mertonensis is a biennial for me. I started some from seed two years ago and they bloomed in the most spectacular way last year! Here is a tip about the 'alba' form of purpurea: most of the common foxglove will throw an 'alba' seedling occasionally. You can tell they will be the 'alba' ones by looking at the leaf stems. The purple flowered seelings will have a purplish cast to the green. The alba ones will not. One of the nicest foxgloves I've ever grown is African Foxglove, which is not a Digitalis at all but Ceratotheca triloba. Unfortunately it is an annual, but it was definitely worth growing. Here's a closeup of one of the flowers. There are more photos of it in the plantfiles.
