Early Goldenrod (Solidago juncea) vs. Sweet Goldenrod (Solidago odora)
Updated July 20th, 2025These two goldenrods are frequently confused in their small range of overlap. Both bloom early, have smooth leaves, upper leaves that lack serrations, and grow in dry habitats, often those with sandy, acidic soil. They are easily distinguished by inflorescence shape, floret count per flowerhead, leaf bases, and serrations on lower leaves. S. juncea ranges farther north, prefers more nutrient-rich, less-acidic soil, and is more likely in anthropogenic or human-disturbed habitats. S. odora ranges farther south and is strictly limited to sites with acidic, nutrient-poor soils, but less likely on sites disturbed or altered by humans.
