Chrysanthemum coccineum (Tanacetum coccineum)--Pyrethrum Daisy
Hardiness Zones: 3 to 7
Height: 2 ft Spread: 2 ft
Type: herbaceous perennial
Flowers: Red, pink, purple, white
Comments: Pyrethrum Daisy produces (Vis. 1) daisy-like
flowers in summer. Pyrethrum prefers a well-drained soil
and full sun or partial shade. They grow best in cooler
climates but some winter protection is advisable. The
plants are fertilized regularly during the growing season.
Sometimes Pyrethrum Daisies are cut down in June after the
first bloom to promote a fall bloom. The second blooming is
much poorer than the first. Pyrethrums, other than dwarf
varieties, need staking early in the season.
Propagation: Propagation is by division, seed or stem
cuttings. The stem cuttings are rooted in sand. Division
is done in late summer or early spring. Divisions done in
late summer have to be well-watered when replanted. Seed
germinates in one to two weeks at temperatures between 60
and 70 degrees.
Cultivars:
'James Kelway' - Dark red flowers.
'Robinson Hybrids' - Large flowers in a mix of colors.
