8" tall x 15-18" wide. Stachys byzantina 'Helen Von Stein' is a mounding, large-leafed version of common Lamb's Ear with soft silver leaves. Easily grown in any average to poor garden soil with good drainage. Since it rarely flowers and it cutting propagated, it is a great choice to replace standard lamb's ears, which reseeds and can becomes weedy. Not recommended for regions with hot, humid summers, as the woolly foliage will "melt" from the humidity. Good for Firescaping.
