Baccharis salicifolia inhabits moist, partly shady areas at low elevations, often forming large clumps, and it flowers most of the year. Leaves and stems are usually hairless, and often somewhat sticky due to small resin glands. Plants produce one or a few stems, branching towards the top, the branches pointing upwards or outwards. Relatively long, narrow leaves grow all along the stems; they have small, well-separated teeth along the margins, one prominent central vein and two fainter side veins near the edge.
The inflorescence is a rounded or pyramidal cluster of small, white discoid flowerheads. Heads have either staminate florets (17 to 48) or pistillate florets (50 to 150). Phyllaries are pale green or reddish, arranged in 4 to 5 rows.
