Diablo Ninebark (Physocarpus) shrub with emerging buds and fully open flowers. This shrub reinforces my purple and white shades in my springtime perennial garden. The leaves and the white flowers both have purple undertones. This species is also suitable to my sustainable plans; it is heat and drought resistant. I take advantage of perennial’s deep roots and keep my watering to only once or twice each year. Newly planted perennials are pampered with weekly deep watering as their root systems become established.
