ID guidance

Almost always with blue, violet or purplish flowers; yellow flowers are rare. Leaves not strongly decurrent (i.e. wings extend a short way down stem below each leaf), unlike S officinale.  Nutlets dull and minutely tuberculate.  Not stoloniferous, unlike S x hidcotense, which also has blue flowers, often flushed pink or red.
