Sun King Spikenard is an unusual plant with many cool features. It's a perennial that will grow into a 3' x 3' mound in a New York minute thanks to its huge compound leaves. They create a stunning mass of bright chartreuse. Little flower clusters on thin stems form in summer that turn into small, black inedible berries. Best of all it loves the shade, which is right where you want something bright and eye-catching!  Full shade may turn the leaves a little darker, but just an hour or two full sun will keep them bright chartreuse. It wants consistent moisture in well-drained soil. Deer-resistant but bees love it! Hardy zones 4-8, native to Japan. Give them a try - but hurry - supplies are limited!
