Faits intéressants

Giant Goldenrod is a highly adaptable species. It can grow across a range of terrains and in many conditions. It is most commonly found in seasonally wet or moist areas but can also be found in dry ones. It is excellent for rehabilitating meadows or areas near water. It may be too large for many small gardens. It does handle the occasional flooding well. Avoid planting where a tidy, compact border is desired.
