What’s in a name? When it’s Peter Cottontail, you won’t be surprised to see fluffy, large, ivory-white flowers on this long-blooming perennial! And with its low mounding habit of green foliage, Peter Cottontail adds texture to the garden and is a great companion plant for most perennials. Yarrows thrive in average to poor soil, not in rich soil, which makes plants too tall and floppy. When flowers have faded, cut plants back by half. It may be named after a fictional rabbit, but the real ones tend to leave this plant alone! Drought resistant and attracts pollinators.
