Plant Type: Perennials

Scented flowers of the richest, deepest crimson with dark green tinged with purple leaves. Once they've finished flowering cut right back and leave for even better flowers in the second year.

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.
