Having seen this late in the season last year, I was keen to see when it would come up this year. And the answer - very quickly in the last 3 weeks! Not a sign in the last weekend in March, and then last weekend (19th April) here it is, looking almost ready to flower. Always a special plant to see. This patch is unusual because it is in beech plantation with sycamore - planted about 1960 - and apparently not in an area of ancient woodland.
