Red Campion
Silene dioica
flowerRed Campion is a biennial or short-lived perennial wildflower native to Europe, known for its vibrant magenta-pink flowers that bloom in spring and early summer. The plant produces loose, airy clusters of five-petaled flowers on branching stems with soft, hairy foliage. It self-seeds readily and attracts pollinators, making it a charming addition to cottage gardens and naturalized areas.

Germination & Seedling
2-3 weeksTiny seedlings with cotyledons emerge and develop first true leaves. Growth is slow initially.
Keep soil lightly moist but not waterlogged. Provide adequate light and good air circulation to prevent damping off. Do not cover seeds with soil.
Rosette Formation (First Year)
3-4 monthsPlant develops a low rosette of hairy, lance-shaped leaves close to the ground. Growth is vegetative with no flowering.
Allow plant to establish a strong root system. Thin seedlings to proper spacing. Water moderately. Remove any flower buds if they appear to encourage foliage growth.
Bolting & Stem Elongation
3-4 weeksTall flowering stems emerge from the rosette, growing 24-36 inches tall with branching lateral shoots. Buds begin to form at stem tips.
Provide support with stakes if grown in windy locations or rich soil (causes leggy growth). Reduce nitrogen fertilizer to prevent excessive vegetative growth at expense of flowers.
Flowering
6-8 weeksLoose clusters of bright magenta-pink flowers (occasionally white) open progressively along branching stems. Flowers are 5-petaled and slightly fragrant.
Deadhead spent flowers to encourage continued blooming and prevent excessive self-seeding. Water during prolonged dry spells. No feeding necessary at this stage.
Seed Maturation & Senescence
4-6 weeksFlowers fade and develop swollen seed capsules. Foliage may yellow. Plant begins to decline as energy shifts to seed production.
Allow some flowers to go to seed for self-seeding next year, or deadhead completely to prevent unwanted volunteers. Stop watering gradually as plant naturally dries down.

Harvest Tips
Red Campion is grown as an ornamental flower, not harvested. Cut flowers for arrangements at peak bloom in early morning when stems are hydrated. For seed collection, allow flower heads to fully dry on the plant, then harvest capsules before they split naturally. Store seeds in cool, dry place for 1-2 years.
Fun Facts
- 🌱 Red Campion is dioecious, meaning individual plants are either male or female—only female plants produce seeds, while males produce more abundant pollen
- 🌱 In the British countryside, Red Campion commonly hybridizes with the closely related White Campion (Silene latifolia), creating pink intermediate flowers
- 🌱 The plant's name 'campion' comes from the Latin 'campus' (field), and 'dioica' refers to its dioecious nature; it's also called Corn Cockle in some regions, though this name more accurately refers to Agrostemma githago
