Supra Purple Pinks

Dianthus 'Supra Purple' is a compact, fast-flowering selection in the Supra interspecific series, with vivid purple flowers whose petals have finely cut, fringed edges. The breeder describes Supra as a first-year flowering perennial and lists Purple among the series colors; Brookgreen Gardens also records this exact cultivar as a perennial. [Hem Genetics](https://www.hemgenetics.nl/en/assortment/dianthus%20%20interspecific/supra) · [Brookgreen Gardens](https://www.brookgreen.org/plant-collection/name/dianthus-supra-purple) ## Garden Use The exact Purple selection is listed at about 25–30 cm (10–12 inches) tall and is suited to a sunny flower bed, container, or cutting garden. The breeder's broader series listing gives a garden spread of about 25–35 cm (10–14 inches), so allow a little room around the mound. Brookgreen Gardens reports successful warm- and cool-season plantings in its region, while the breeder lists the series as hardy from USDA Zone 5; local flowering and winter behavior will vary with climate.

The breeder describes the series as heat and cold tolerant. Choose a well-drained site so the crown does not remain wet.

Remove spent stems to tidy the mound and make room for fresh growth. [Brookgreen Gardens](https://www.brookgreen.org/plant-collection/name/dianthus-supra-purple)
