If you’re not familiar with Achillea ptarmica, this species is unique from what you’d expect from the classic A. millefolium types. ‘Peter Cottontail’ has a look that’s reminiscent of Baby’s Breath, with large, ivory white flowers that are produced over a low, mounding habit of green foliage. Compared to A. millefolium types, the flower clusters on this perennial are more singular and well-spaced-great for adding texture to the garden! Compared to other A. ptarmica types on the market, this perennial has larger individual flowers and a more polished habit. Although this perennial is named after a fictional rabbit, ‘Peter Cottontail’, it is mostly unbothered by both deer and rabbits. Hardy Zones 3-8. Loves the sun Mature Height: 18-24″ Spread: 28-30″ Dormant shipping in winter.
