How to Grow Pyrethrum / Tanacetum Plants

Guide to Growing Painted Daisy, Coccineum, Tansy, Feverfew and Costmary

Pyrethrum (Tanacetum) are hardy perennials that are frequently grown as hardy annuals in the garden.

They vary in height from 10 to 90 cm; this makes them a versatile plant for use in borders or edging.

Plants bloom from the middle of spring to summer, and carry flowers reminiscent of daisies; the petals may be red, purple, pink or white. Foliage is often fern-like.

Some common names for Pyrethrum (Tanacetum) plant genus members include Painted Daisy, Tansy, and Feverfew.

How to Grow Painted Daisy (Pyrethrum / Tanacetum)

The seeds of Pyrethrum / Tanacetum plant species such as Painted daisy and Feverfew can be sown out in early autumn or early spring; once sown lightly cover the painted daisy seeds. They like to grow in a sunny part of the garden that has good drainage, and a soil of pH 6 to 7.5. The plants should be spaced from 20 cm (small varieties) to 60 cm (large Pyrethrum / Tanacetum species) apart.

If growing indoors first then sow the seeds about two months in advance. The seeds should take about 3 to 9 weeks to germinate at 12 degrees centigrade. They can be transplanted outdoors either in autumn or before the last frost of spring.

Caring for feverfew, Painted daisies, and other Pyrethrum / Tanacetum Plants in the Garden

Once growing pinching back young Painted daisies or Feverfew at the tips will encourage branching. Following the end of flowering cut back the plants lightly and feed them; the plants should then produce a further bloom. If you require more plants then they can be propagated by division of the plants in the spring time.
