Izu tree (Distylium) is a fast-growing shrub that has become increasingly popular over the last decade. "Its adaptability and ease of care moved it into the spotlight as it can handle wet but not flooded soils to drier conditions and part shade to full sun," says Jon Roethling, the director of Reynolda Gardens. "Leaves can range from a blue-green to lustrous dark green and typically tend to be narrower in appearance."
