Non Native or Just Odd

This is a space for stuff that is not mentioned in any ‘Wildflowers of the UK’ book or is a ‘non native to the UK’ species that I just find odd being here.

Grassnut

Triteleia laxa

T. laxa is a perennial with linear basal leaves and loose umbels of funnel-shaped, mid- to deep blue flowers 3-4cm in length, on stems to 50cm in early summer.  It is native to California where it is a common wildflower, and it is occasionally found in southwestern Oregon. It bears a tall, naked stem topped with a spray of smaller stalks, each ending in a purple or blue flower. The flower is tubular, opening into a sharply six-pointed star. The plant grows from a corm which is edible and similar in taste and use as the potato.
