Dianthus Seeds

Spicy Fragrance and Long Bloom from Seed

Dianthus seeds grow into hardy perennial plants known for their finely cut petals and clove-like scent. Many varieties bloom from mid-spring into summer, with some offering repeat flowering when conditions are right. Seed-grown dianthus may vary slightly in color, flower shape, or plant size, which is part of the appeal of growing plants from seed.

Most dianthus varieties are perennial in USDA zones 5–9, though bloom timing and winter hardiness can vary by type. When grown from seed, plants typically focus on root and foliage development in their first season, with stronger flowering in following years.

Growing dianthus from seed gives gardeners more variety and allows plants to adapt naturally to local growing conditions.

How to Start Dianthus Seeds

Start dianthus seeds indoors in a sunny location using a well-drained seed-starting mix. Press seeds lightly into the soil surface and keep evenly moist until germination. Once seedlings develop several sets of true leaves, harden them off gradually before transplanting outdoors after the risk of frost has passed.
