Anacyclus pyrethrum: complete guide

Overview

Anacyclus pyrethrum, commonly called Atlas daisy or Roman pellitory, is an elegant alpine plant native to North Africa. This charming plant produces delicate flowers with distinctive white upper sides and red undersides, creating a striking contrast. Its compact growth habit makes it ideal for rock gardens, borders, and container cultivation.

Appearance and Bloom

The Atlas daisy grows to about 30-40 cm tall and forms a neat rosette of finely cut, feathery foliage. Flowers appear from May through September with their characteristic two-toned appearance. The long flowering period and low-growing habit make them perfect gap-fillers in summer schemes.

Ideal Location

This plant thrives in full sun with at least 6 hours of direct sunlight daily. It loves warmth and protected, draft-free locations. Perfect for south-facing borders or against a sunny wall where it receives maximum heat.

Soil Requirements

Well-draining soil is essential, improved with sand and grit. Anacyclus pyrethrum is not fussy and grows even in poor soil. Slightly acidic to neutral pH (6-7) is ideal. Avoid heavy clay soils that retain water.

Watering

Water moderately during the growing season, allowing soil to dry between waterings. Check regularly to prevent waterlogging. For container plants, water until 1 cm below rim level. In winter, water minimally.

Pruning

Pruning is not essential, but regularly deadhead spent flowers to encourage continued blooming. After flowering, stems can be cut back halfway to maintain compact growth.

Maintenance Calendar

March: Plant or repot. May-September: Regular deadheading of faded flowers. October: Prepare for winter, reduce watering. November-February: Dormancy period with minimal care.

Winter Hardiness

Anacyclus pyrethrum is hardy to approximately -5 to -10 degrees Celsius. In harsh climates, provide winter protection. In containers, move indoors to a cool, dry location for overwintering.

Companion Plants

Pairs well with other drought-lovers like lavender, salvias, and sedums. Also combines nicely with ornamental grasses or small shrubs for contrasting forms.
