Pyrethrum (Tanacetum cinerariifolium)
Benefits
Pyrethrum is a beautiful flowering herb best known as the natural source of pyrethrins, compounds traditionally used in botanical insect control. The daisy like white flowers with sunny yellow centres are not only striking in the garden but also help attract beneficial insects and pollinators. A wonderful companion plant for organic growers, it supports a balanced ecosystem while adding cottage garden charm.
Growing Conditions
Season: Sow in autumn or early spring
Soil: Well drained, moderately fertile soil
Watering: Moderate, allow soil to dry slightly between watering
Position: Full sun
Fertilising: Light feeding with compost or diluted liquid fertiliser during active growth
Use
Flowers are traditionally harvested when fully open and dried for natural insect repellent preparations. Pyrethrum has long been valued in sustainable gardening for botanical pest control applications.
Growing Tips
Sow seeds on the surface and lightly press in as they require light to germinate. Keep soil moist but not waterlogged during germination. Plants prefer good airflow and dislike heavy, wet soils. Deadhead to encourage continued flowering.
Companion Plants
Grow near brassicas, fruit trees, and vegetable beds where natural insect management is desired.
