SULPHUR PINK SEEDS

Dianthus knappii

An obscure little Dianthus with yellow flowers. Rather inconspicuous during the day, these flowers literally glow during the crepuscular hours, beckoning moths and insects and the odd curious human. Impossible to photograph, it is a phenomenon that must be witnessed firsthand.

Like most of the genus, Sulphur Pinks prefer to grow in full sun and well-drained soil. This species especially is a marvelous companion for Lavender angustifolia and Salvia nemorosa. Both the lush green foliage and yellow flowers make for fantastic contrast. Ideal in a moon garden with Helichrysums and Artemisias.

Start indoors 8-10 weeks before the last spring frost. Sow seeds just below the surface of moist soil, pressing to keep seeds snug. Mist with warm water and cover with plastic. Kept warm (70°F) and moist in bright light, seeds will germinate within a week or two. Prick out seedlings once they have true leaves to grow on in individual 3" pots in bright light at warm room temperature. Water from the bottom, and allow to dry out slightly between waterings. Fertilize weekly with dilute fish and seaweed extracts to hasten root development. Transplant outdoors into well-drained soil in full sun once all danger of frost has passed.

Very slow-growing initially, plants are tough once established and very long-lived. Hardy to at least zone 5, but requires drainage to overwinter. Moderately deer-resistant. Flowers are edible, but lack the sweet scent of other species. Best as an ornamental. Flowers in late spring. In a perennial border it works well with Lamb's Ears, as well as Echinaceas, which begin blooming just as this species stops.

Packet contains at least 50 seeds.
