Stems of hackelia floribunda
tend to grow at a 45 degree angle, and carry elongated, branched clusters of tiny, pale blue, funnel-shaped flowers. Individual flowers have five lobes around a narrow central tube (yellow-green inside), the top of which is slightly raised above the petal bases. They are about a quarter of an inch in diameter. Fruits are small, flattened nutlets, with a line of prickles along the edge, a factor which distinguishes this plant from the similar hackelia micrantha. Hackelia floribunda is a quite tall plant, and has relatively large leaves, again different to many other boraginaceae species.
