Common Name: Pinks

(Formerly named 'Siskin Clock') A mesmerizing dianthus! The young flowers have very light pink petals with a deep maroon picotee edge and eye. As they age, the petals fade to white and the picotee edges changes to magenta. These awesome blooms carpet loose mounds of gray-green foliage in early summer. If deadheaded, they will rebloom in the fall.

Homeowner Growing & Maintenance Tips:

Dianthus grow best in loose, well-drained, neutral to slightly alkaline soils. Lime can be added to the soil if it is naturally acidic to raise the pH. Dianthus can be grown in full sun or part shade, but the foliage will not be as lush and fewer flowers will be produced if it is grown in hot, dry areas. Regular watering during prolonged dry spells will be necessary. However, they are tolerant of short periods of dryness.

Do a thorough clean-up in the fall to prevent pest and disease problems, and add a layer of mulch to protect the evergreen foliage. As soon as the weather begins to warm up, remove all of this mulch to prevent crown rot.

Fun Facts:

What came first--the color or the flower? The color we call "pink" was actually named after "Pinks,"  the common name of Dianthus.

Did you know Dianthus flowers are edible?  The individual petals have a sweet taste just like their perfumed scent.
