Unknown plant in the southwest of Ireland

[Thomas Lamp]

Hi, 
This plant growing in the southwest of Ireland, between stones. 12-15cm
up, flowers remaining on Digitalis, light yellow; laeves like Tropaeolum.
I have no idea!
Shannon and Diane reply in the shrub-forum, they guess:
Hmmm..The flowers look just like a Lupine or a  Thermoptis but that foliage?? 

The flowers look almost like fabiana but the foliage on it is
needle-like.  Some variety of Heather?
