Tanacetum coccineum: complete guide

Overview

Persian Daisy (Tanacetum coccineum), also called Painted Daisy or Pyrethrum, is a robust perennial from the Asteraceae family native to mountains of Eastern Europe through Iran and Central Asia. This plant distinguishes itself through beautiful red to pink flowers rising above finely-textured feathery foliage. With compact growth habit and extended flowering period, Tanacetum coccineum proves an excellent choice for borders and cutting gardens alike.

As a garden plant, this grows extraordinarily well in temperate climates. The plant reaches 60 to 80 centimetres in height forming dense, well-defined flower clusters. Furthermore, Persian Daisy proves hardier than many other daisy species, making it ideal for virtually every average garden.

Appearance & bloom

Persian Daisy grows as a perennial featuring finely-divided, feathery foliage that proves exceptionally decorative. Leaves display bright green colouration with intricate division, giving the plant an airy appearance.

Flowers emerge in May-June (early to mid-summer) in red, pink or white (depending on cultivar), often with yellow centres. Flowers occur as single or double forms depending on variety. Regular deadheading encourages continued flowering through autumn. The plant makes an excellent cut flower.

Ideal location

Persian Daisy performs best in sunny positions: minimum 6 hours direct sun. In semi-shade the plant flowers adequately, though less abundantly. A site with good air circulation prevents fungal problems.

This plant accommodates virtually all garden conditions. It tolerates wind exposure, making it suitable for exposed borders. In very hot climates, light afternoon shade proves welcome.

Soil

Persian Daisy proves undemanding and grows in virtually any soil type. However, well-draining soil promotes better growth and disease prevention. The plant tolerates heavy clay, though adding sand and compost improves conditions substantially.

Soil pH proves non-critical (5.5-7.5 proves equally fine). The plant adapts to poor soils but prefers good nutrition. For borders, incorporate compost or aged manure for markedly improved results.

Watering

Once established (after several months), supplemental water proves rarely necessary. Water when the top soil layer feels dry. During the first growing season, provide regular moisture for good establishment.

Excessive moisture promotes fungal disease and poor growth. During dry spells, provide thorough deep watering, especially for full flowering. The plant proves more drought-tolerant than many other flowering perennials.

Pruning

Persian Daisy responds well to regular deadheading. This stimulates continuous flower production throughout the season. Following early June flowering, gentle trimming encourages second blooming in autumn.

In early spring, remove weak or dead shoots. In autumn, trim the plant back after final flowering for winter dormancy.

Maintenance calendar

January-February: Dormancy, remove dead leaves. March-April: Growth beginning, apply fertilizer, early pruning. May-June: Flowering period, deadhead for more blooms. July-August: Continuous flowering, water during dry periods. September-October: Second flowering flush, continue deadheading. November-December: Flowering decrease, dormancy preparation.

Winter hardiness

Persian Daisy proves very winter-hardy and suitable for USDA zone 3 (-40 to -34 degrees Celsius). The plant withstands severe winters excellently. Winter protection rarely becomes necessary. In very wet winters, good drainage prevents rotting.

Companion plants

Flowers attract numerous pollinators: bees, butterflies and bumblebees. This plant proves highly valuable for ecological gardens and insect borders. The fine foliage also provides shelter for tiny insects.

Closing remarks

Persian Daisy represents a classic garden plant never going out of favour. With modest care, this beautiful plant thrives and delivers years of full colour. Source this plant at Intratuin and Gamma, where expert advice supports cultivar selection and colour preferences.
