Yes, the 'What is it Wednesday' Plant is Turtlehead or Chelone. This plant is a win/win. It gets its name from the shape of its unusual flowers, which look like the head of a snapper turtle. Here is why you need it in your garden.
#1 It is blooming now. When so much is dying back for the year.
#2 It thrives in part sun, actually mine grows in more shade than sun.
#3 Very reliable perennial that spreads but is not invasive.
#4 Grows from 1 to 8 feet....and spreads into a great clump.
Try it I think you will like it!!!
