Well, no sooner have I made my post and I get an answer - Wood Anemone and a special thank you Alison for  your addition: "These gorgeous little wood anemones are perfect for naturalising in a mixed border, at the edge of a woodland area, or around the base of deciduous shrubs, where they shine out like jewels. For maximum impact plant in bold drifts. A stunning little plant that lifts the spirits in spring". I think the last sentence would describe Jane!
Shell - I like your style and it matches Jane's perfectly.
