Dianthus: A Top-Recommended Perennial for Canadian Gardens

There are some plants I have come to love as a mature gardener, though I certainly didn’t appreciate them in my early years as a greenhouse kid. Dianthus isn’t one of them – I have always admired them, with their spicy clove-like fragrance being the big draw. Their common name, pinks, refers to the edges of their petals that resemble the blades of pinking shears.

Combining long-lasting blooms, beautiful fragrance, cold hardiness, and a low-growing, tidy mounded habit, Dianthus is top-recommended perennial for Canadian gardens.

Proven Winners has taken all those classic Dianthus qualities and elevated them with larger blooms, improved flowering and exceptional garden performance. Their Fruit Punch^® and Paint the Town series of Dianthus are hardy to zone 4, making them reliable perennials for much of Canada. Once established, they return year after year with very little fuss.

Where to Grow Dianthus

Dianthus are perfect for sunny gardens, thriving in full sun to part sun, which means they receive six or more hours of sunshine per day. Well-drained soil is essential for Dianthus, as soggy soil can cause crown rot. Raised beds, rock gardens, edging borders, cottage gardens, and containers all work for these perennials. Their compact size and fragrance makes them ideal for planting near paths or patios where their fragrance can be enjoyed up close.

Dianthus Flowers and Foliage

Flowering typically begins in late spring to early summer. Fruit Punch and Paint the Town varieties will continue blooming or will rebloom intermittently throughout the growing season if deadheaded regularly.

Dianthus flowers come in shades of coral, pink, magenta, red, and white, and often bear a contrasting eye that attracts pollinators like bees and butterflies. The Paint the Town series features profuse 2 - 3 cm (.75 - 1 in) single flowers, and the Fruit Punch^® series has fully double 3 - 5 cm (1.25 - 2 in) flowers. All are equally fragrant, and I am a fan of every single one in these series!

Another standout feature is their foliage which adds ornamental value beyond the flowering season. Even when not in bloom, the evergreen to semi-evergreen, blue-green, neatly mounded foliage provides color, structure and texture to the garden.

How to Care for Dianthus

Dianthus is refreshingly easy to grow. Here is what I’ve found that works for Canadian gardens: Plant in well-drained, evenly moist soil. Avoid soggy soil; these plants do not like having wet feet.

• Plant them in a sunny location with good air circulation.
• Avoid planting them in overly rich or wet soil.
• Water them regularly while the roots are establishing. Once mature, Dianthus are relatively drought tolerant for short periods of time.
• Removing the spent flowers encourages additional blooming and keeps plants looking tidy.
• Every few years, mature clumps can be divided if needed to refresh the plants’ vigor and encourage continued flowering.

For gardeners looking for a perennial that offers fragrance, pollinator appeal, an extended bloom time and excellent cold hardiness, Proven Winners’ Dianthus checks all the boxes. They are proof that low-maintenance plants can bring plenty of beauty and charm to the garden.
