The near black foliage of 'Holy Grail' is an epic contrast against the huge, deep red flowers that bloom from mid summer to early fall. Tolerant of a wide range of soils including boggy ones, consider this Rose Mallow for low lying wet spots or even zone 1 of a rain garden where water stands for a while post rain events. This shrub also makes for a nice border plants, landscape planting, or specimen.
Full sun - part sun. Average, moist-wet soil. Protect from winter winds. Zone 4-9.
Deer resistant, attracts pollinators including hummingbirds.
Deadheading can maintain neat appearance but is not necessary for continued blooming.
Fertilize throughout growing season for best results.
Cut back stems to approximately 3-4 inches in late fall.
