General Information : Abundance of bright yellow flowers from Summer to Fall lure pollinators in with nectar-rich blooms. Plus, it makes an excellent cut flower for bouquets. When not in bloom, the finely textured foliage resembles ornamental grass – adding a nice texture to any garden.
Idea & Tips : Plant in full sun in well-drained soil to avoid prolonged saturation to roots. Mulching can enhance Winter protection in colder regions. Avoid trimming back the foliage in late Fall to early Winter to protect the crown of the plant throughout the Winter months. When the weather begins to warm, untidy-looking foliage can be pulled away.
