It is VERY frustrating. I've been picking what I can (and embarrassing my entire family in the process) and so far I've got 2 quart bags full in the freezer. I'm saving them for when visitors come since Alex and Eric don't partake. Book your tickets now for blackberry crumble in Bury St. Edmunds!
There is also Lupin which is beautiful and this yellow weed which looks a lot like dill but I don't think it is even though it kind of faintly smells like dill, maybe it is the British cousin.
