To care for pink feverfew (Tanacetum parthenium), ensure it gets full sun or partial shade, well-drained soil, and regular watering, especially when young, and consider companion planting with marigolds, basil, or chives. 
Here's a more detailed guide:
Full Sun to Partial Shade:
Feverfew thrives in sunny locations but can tolerate some shade, especially in the afternoon. 
Spacing:
Give each plant ample space (12-18 inches) to allow for growth and air circulation. 
Well-Drained Soil:
Feverfew prefers light, well-drained soil with a slightly acidic to neutral pH (6.0-7.2). 
Watering:
Water regularly, especially when the plant is young and establishing its roots. Allow the soil to dry out slightly between waterings to prevent root rot.
