Triteleia laxa (previously Brodiaea laxa) is a triplet lily known by several common names, including Ithuriel's spear,[1] common triteleia and grassnut.

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 plant grows from a corm which is edible and similar in taste and use as the potato.
