Grass-leaved Goldenrod or Flat-top Goldenrod
Full sun to light shade
Average soil and moisture but adaptable to both dry and wet conditions.
Grows 2' to 3' tall in my observation but may be taller in wetter settings. Spreads fairly quickly.
Meadow settings are recommended
Although these aren’t actually a member of the Solidago family, their brilliant gold blooms, popularity with a wide range of small critters and a general capacity to carry on, no matter what life throws at them, means that they fit right in with their common-name sakes.
I think they would fit right into a wildflower garden or a medium to dry mixed meadow planting. In a dryish site they aren’t likely to overwhelm neighbours of similar heights. They can be quite assertive in areas with consistent moisture and would play best with other species that are also assertive or accomplished at holding their space, like Red Monarda, Wild Bergamot, Obedient Plant, Prairie Sundrops (Oenothera pilosella), Canada Anemone, Golden Groundsel and Joe-Pye Weed.
Their heigh in dry locations been around 18” to 30” but they can stretch to around 40” in wetter areas.
They enjoy sun but will get by with part day shade, as long as they have a few hours of direct rays.
