How to Grow Painted Daisy and Pyrethrum

Tanacetum Germination Information

Tanacetum is the botanical name for Painted Daisy and Pyrethrum
Tanacetum Seed Germination How to Sow Tanacetum:
  • Sow indoors, in early spring, at a temperature of 55°
  • Barely cover the seeds and expect germination in 20-25 days
  • Alternatively, sow seeds outdoors in spring or summer, up to 2 months before first frost
  • Plants will take two years to flower from seed
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Tanacetum:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Space 12 inches apart in full sun (in the North) or light shade (in the South)

Soil: Site in a light, sandy, rich, well-drained soil. Keep evenly moist when establishing, but thereafter they can be grown on the dry side. Feed moderately with a balanced fertilizer

Additional Care: After flowering, cut plants back hard to promote a second flush of flowers in the fall. In warm climates, plants may need replanting every spring. Staking may be necessary when pants are in flower

Appearance and Use:

Also known as Chrysanthemum coccineum, it is the source of the insecticide Pyrethrum. Grow it in borders, use as bedding, and harvest for fresh cut flowers. A vigorous upright grower, 24 inches by 18 inches, it is covered in flowers in May and June. The flowers are 3 inch, single or double, daisy-like flowerheads that are held above the foliage by long, wiry stems. The ray florets are red, pink, or white and the disk florets are yellow. The deeply divided, fern-like leaves are dark green
