Dianthus chinensis in Curtis Botanical Magazine

There are a large numbers of species and hybrids of Dianthus. They make good edgings for flower beds and are excellent for cottage gardens. In Phoenix the pinks on these pictures are best planted in the fall, as soon as the temperature becomes cooler at night. They will grow and bloom quietly during the winter and then will give an explosion of flowers at the end of March until May. They are better removed in summer.

Blooming Habits:
The flowers can reach one inch in diameter (2.5 cm) and have a spicy scent.

Propagation:
They can be started outside or inside. In mild winter areas, plant them or start them in late fall. In cold winter areas, start them inside 6 weeks before the last frost date, or sow them in place 2 weeks before the last frost date. Germination takes a week to a week and a half. Cover the seeds with a thin layer of mulch. Transplant or thin out 8 inches apart (20 cm). Deadhead regularly, and trim severely when the blossom slows down to get a second flush.
