Broadleaf Tickseed

A little-known native of the southern Appalachians, Broadleaf Tickseed brings yellow corymbs and bold oval foliage to the shaded woodland edge from midsummer through September.

Broadleaf Tickseed occupies a specific ecological niche that most ornamental plants ignore: moist, rich woodland soils at middle to lower elevations in Georgia, North Carolina, South Carolina, and Tennessee. It is a plant with a genuine regional identity, not widely distributed but doing its particular job very well in the landscapes where it belongs. Growing to about four feet, it produces oval leaves up to eight inches long that create a substantial, layered presence before the flowers even arrive.

The blooms come in corymbs of yellow flower heads that open from July through September, landing squarely in the difficult late-summer gap when many perennials have finished. Bees pollinate the flowers and the plant spreads by rhizomes, gradually forming colonies rather than staying in a tight clump. This is a plant for naturalized woodland plantings at the forest edge, where it can establish without competition from lawn or formal borders. Its requirements are not complicated: part shade, moisture, and soil with some organic richness. Within those conditions, it is a reliable and distinctive native contributor to the late-season garden.
