Dianthus barbatus 'Scarlet Fever'

Border Carnation

This sport of 'Heart Attack' has bright, red-orange flowers when the sunlight shines on them, compared to the black-red color of its parent. This type of Dianthus forms large panicles of flowers, filling in the medium height category with a much-needed red color. 'Heart Attack' made waves when it was introduced because of its perennial characteristic rather than biennial and 'Scarlet Fever' shares this same attribute.

Border Carnation Growing and 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.
