Chinese Pinks Dianthus Seeds

Chinese pink dianthus has long been a popular variety for its many notable features. As recorded in “Notes on the State of Virginia” in 1807, Thomas Jefferson grew Chinese pinks along his meandering flower borders. 

Prolific and a snap to grow, it’s easy to understand the fascination with this beautiful flower. Bright, showy pink and white ruffled petals encircle dark centres. Thriving in cool climates, the abundant flowers bloom from late spring all the way through summer on top of thin branched stems that grow up to 90 cm tall and 30 cm wide. Full sun is ideal, although afternoon shade on hot days helps to preserve the life of the flowers. Deadheading spent flowers will promote new growth and extend the blooming period. 

Chinese pinks are versatile and can be planted in flower beds as a border or potted up into containers. The pretty pink flowers are adored by many, as is evident by their widespread availability at nurseries and flower shops. By planting Chinese pinks in your own garden, you can bypass the overpriced retail outlets and enjoy the satisfaction of a classic variety flourishing from seed to fabulous flowers.

GROWING INSTRUCTIONS

Often grown in cottage gardens, perennial beds and containers, Dianthus showcases bushy foliage and brightly coloured flowers of many shades. Seeds can easily be started indoors or outdoors. Sow directly outside in late spring or early summer after the danger of frost has passed. 

Six to eight weeks before the last frost, seeds can be started in flats or separate containers. Sow seeds on the surface of moist soil and mist well. Put them in a bright location, under lights or by a sunny window, and keep them moist. Dianthus prefers cooler weather when germinating. Maintain an ambient temperature of 10-13 degrees. When they start to sprout, thin them out to provide space and good air flow. Seedlings can then be hardened off and transplanted outdoors after the danger of frost has passed. 

Dianthus will do best in full sun, although in hot regions, afternoon shade will help extend the blooming window. Plant Dianthus in rich, well-drained, loamy soil. Keep the soil moist with regular watering, but don’t allow it to become waterlogged. Dianthus is tolerant to many climates, except extreme heat. It will withstand light frosts, but will be killed by hard freezes. To promote blooming and vigorous growth, fertilize Dianthus once every couple of months. 

Space Dianthus about 20 cm apart to make room for the dense foliage. The flowers will self-seed at the end of the growing season, providing gardeners with a fresh bunch of volunteers every spring. 

QUICK FACTS

- Dianthus seeds will remain viable for 2 years if stored in a cool, dark place, ideally between 4 and 10⁰C. After that, the germination rate may start to go down.
