The green leaves of phacelia pedicellata
are quite distinctive; the largest (near the base) are divided into 7 leaflets, on short stalks, with irregularly lobed or toothed edges. Those a little higher up the stem have 5 or 3 leaflets, while the highest are smaller, less toothed and may be undivided. Leaves and stems are glandular, covered in short brownish hairs. The bell-shaped flowers have five pink or bluish lobes around a center of five stamens topped by white anthers, and a divided style. Like most phacelia, the thin stamens project well beyond the lobes.
The plant forms dense clusters of flowers; the upper portion of the stem branches several times (into short pedicels, hence the species name pedicellata), each segment bearing a dozen or more blooms. Flowers emit a bad scent, and can cause a rash if touched, both characteristics common to many other phacelia species.
