Our friend thinks not. I happen to love the flavor. As with cranberries, use 1/2 the sugar a recipe asks for to get the full flavor. Boil it with a little water and sugar and dump it on vanilla ice cream. I'd go for a rhubarb gelato too, if anybody made it. Or a tarte.
I drove my Smart Car (in photo) over to check the patch and observed that it is happy but has bolted. I chopped off those cool flowers and Mrs. BD put them in a vase.
