About Yarrow
Yarrow is one of the most widely distributed flowering plants in the northern hemisphere, growing in grassland, roadsides and poor ground across Europe, Asia and North America. Its botanical name, Achillea millefolium, refers both to Achilles — who by legend used it to staunch soldiers wounds — and to the finely divided, almost feathery leaves. It spreads by creeping rhizomes as well as seed, which makes it persistent in lawns and borders alike. Its deep, fibrous roots and tolerance of drought and poor soil are why it turns up so often in meadow and low-input planting schemes.
Growing notes
- Midsummer flowering is a reliable seasonal indicator
- Drought-tolerant; deep root system makes it a useful dynamic accumulator
- Always consult a qualified medical or herbal practitioner before medicinal use.
Pet caution: Yarrow is listed as potentially harmful to cats and/or dogs. Keep pets from grazing on it, and contact a vet if you suspect your animal has eaten some.
