Hackelia floribunda is a species of flowering plant in the borage family known by the common names large-flowered stickseed and manyflower stickseed. It is native to much of the western half of North America, where it is most often found in areas which are wet during the springtime, such as meadows. This is a lush biennial or perennial herb with hairy stems reaching a maximum height of about a meter. They emerge as a leafy clump, surrounded by many smooth lance-shaped leaves up to 24 centimeters long. There are few leaves at the ends of the stems, which hold cyme inflorescences of blue flowers. Each flower has five lobes with petallike appendages at their bases. The fruit is a tiny, mildly prickly nutlet.
