Faits intéressants
Squarrose Goldenrod has sturdy, upright stems that form tall clusters of bright yellow flowers. As it tends to keep to itself, it will fit in well in a smaller garden but towards the back as it can grow up to 5 feet tall. It thrives well-drained soil. It could also be incorporated into naturalized areas and meadows. As with all goldenrods, it is a nectar and pollen magnet for a variety of pollinators.
