Achillea ptarmica 'Peter Cottontail' PP31756

Common Name: Yarrow

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.

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. Thrips, spider mites, root-knot nematode, slugs, Asiatic garden beetle, caterpillars, oriental beetle can also be an issue.

Botrytis, Crown gall, powdery mildew, Rhizoctonia and other stem and root rots are the main diseases to watch out for.

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.
