Dianthus: Growing Conditions and Characteristics
Sun or Shade

- Shade: While they prefer full sun, Dianthus can tolerate partial shade, especially in hotter climates.
Summer or Winter

Perennial or Annual

- Annual: Some varieties, like annual pinks, complete their lifecycle in one growing season.
- Biennial: Certain types of Dianthus may behave as biennials, blooming in their second year and then dying back.
