I went to Dawlish Warren yesterday to look for the Sand Crocus Romulea columnae. It only grows on the Warren and one other place in the UK (Polruan in Cornwall). It was first discovered in 1834. Here is a little more information.
It flowers from late March to April and the flowers only open in the sunshine
Lovely flower
V nice photos. There is quite a lot of it on the warren, but it can be very difficult to find and most of it is on the golf course!
