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.
Yarrow is one of the easiest perennials to grow and is a good choice for beginners. All it needs is full sun and well-drained soil. These plants are an excellent balance of finely textured foliage and bright flower colors.

5.5-6.2
EC (What is EC?):
1.5-2.5 pour through method
Fertility:
Feed with 50-75 ppm at every other watering. Do not over-fertilize, achillea are not heavy feeders.
For Controlled Release or Slow Release Fertilizer, see your preferred supplier for recommended rates for incorporation or top dressing, as it varies by fertilizer.
Vernalization:
Beneficial at 10 weeks of temperatures below 40° F.
Pests & Diseases:
Aphids are the most common pest. Also Root-knot nematode, Asiatic garden beetle, caterpillars, oriental beetle
Crown gall, powdery mildew, rot (Rhizoctonia), stem rot, dodder, root rots
Potting & Timing:
Root Trimming: Roots may be trimmed to fit pot.
Some growers pinch back the original shoot (from a liner) after the roots have formed to encourage branching.
Moisture:
Allow plants to dry thoroughly between waterings.
Planting Level:
Plant crown even with soil line.
PGRs/Pinching:
Multiple applications are typically needed to adequately control height of larger varieties. B-Nine (Daminozide) at 2,500 ppm, tank mixtures of B-Nine at 2000 ppm and Sumagic (Uniconazole) at 3 ppm, or Sumagic alone at 5-10 ppm are all effective.
Lighting:
Bulk plants under short days to prevent early flowering. Achillea flower best under long days.
