Trillium grandiflorum f. polymerum 'Flore Pleno'
Double-flowered American Wake Robin
Trilliums, also known as Wake Robin, or Tri Flowers, are Spring-flowering perennials with flowers with three petals that sit on three leaves. They take a long time to establish and multiply, but then are long-lived, so it is best to leave them alone once planted. 'Double-flowered American Wake Robin' bears fully double white flowers that are 3"-5" in diameter.
