A popular ornamental is the Sweet William or the Dianthus barbatus. Sweet Williams are short-lived and produce small clusters of picturesque flowers in shades of red, pink, white, and purple. Planting one in late spring will give you full bloom the following year or during the first year for some cultivars.

Dianthus knappii (Knapp’s Pink)

Dianthus knappii (Knapp's Pink)

Another Dianthus species that produces small, solitary flowers is the Dianthus knappii or Knapp’s Pink. The other common names for this dianthus are Yellow Pink, Dianthus Yellow Harmony, and Knapp’s Nelke. It is named after the famed botanist Joseph Knapp.

Knapp’s pink features small green leaves and serrated yellow flowers that measure about ½ inches each. The plant grows only up to about 1 ft in height and spreads about 1 ft. It blooms in midsummer.   

How to Help Dianthus Plants Grow Quickly 


As with other gardening plants, the best way to grow dianthus plants quickly is to provide them with the right care and growing conditions. 

Dianthus plants generally require full sun or at least six hours of direct sunlight daily. These plants tolerate partial shade, but full shade is not ideal and will hinder quick growth and flower production. When planting dianthus, it is also best to consider the soil conditions. Well-drained soil will not only allow the plants to grow quickly, but it will also help avoid diseases that can damage plants, like root rot – especially for mat-forming varieties.

The use of fertilizer every six to eight weeks during the growing season also helps dianthus plants to grow quickly. Apply a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20 for optimum growth and abundant blooms. 

Another practice that works for dianthus plants is deadheading. Removing old blooms will encourage the plant to produce another round of flowers, thus prolonging the flowering period. 

While dianthus is an easy-to-grow and undeniably attractive plant, it is worth noting that some cultivars of dianthus are not safe for pets. Some varieties are toxic to dogs, cats, and other animals when ingested. The flowers attract birds and pollinators.
