Syneilesis aconitifolia (Shredded Umbrella Plant) In spring, white, wooly leaves (resembling mayapples) push through the ground and slowly unfold like an umbrella. By midspring these leaves take on a clean, medium green appearance color, with a strong texture and serrated margins, hence the common name. A non-aggressive, herbaceous perennial that spreads slowly via rhizomes; perfectly suited for the woodland garden.
