29th March 2026 - a clump of Bluebells in the Protected Road Verge (PRV 36) along Bourn Bridge Rd has been attracting some recent attention - including some debate as to whether they are native Common Bluebell, or the garden-escape Spanish Bluebell, or a hybrid of the two!
There is some helpful guidance on distinguishing between them on the Wildlife Trust website (link). In brief:
Native Common Bluebell has narrow (1-1.5cm wide) leaves, deep violet-blue (occasionally white) narrow tubular-bell flowers, with only the tips curling back, flowers only on one side of the stem making the stems distinctly droop, with a sweet scent and cream-coloured pollen. Grows in ancient woodland and along woodland edges.
Spanish Bluebell has broad (3cm wide) leaves, paler blue (often white) conical-bell flowers with spreading very open tips, flowers all around the stem, upright stems, with no scent and blue/pale green pollen. Much more vigorous, outcompeting (and hybridising with) the native bluebell. Grows in woodland and along woodland edges, as well as along roadsides and in gardens.
My guess is Spanish/hybrid Bluebell, but I leave it to readers to decide for themselves! (Andy M)
