Growing Duration: Double Variegated Centaurea is a fast growing plant that flowers profusely from spring to summer. Plants begin flowering approximately 8 to 10 weeks after sowing.
Special Features: Double Variegated Centaurea is known for its double flowers, which can reach up to 5 cm in diameter. These flowers are highly prized not only for their beauty, but also for their hardiness and ability to attract pollinators such as bees and butterflies. The plant has an upright growth, reaching a height of 30 to 60 cm, making it perfect for mixed borders and wildflower gardens.
Lighting: Prefers full sun for optimal growth and abundant flowering. Make sure plants receive at least 6 hours of direct sunlight per day.
Watering: Double Variegated Centaurea is fairly drought tolerant once established, but prefers regular watering to keep the soil evenly moist, but well drained. Avoid waterlogging to prevent fungal diseases.
Pests: Centaurea is generally resistant to pests, although it can occasionally be affected by aphids and spider mites. The use of environmentally friendly products, such as potassium soap, is recommended to keep pests under control.
Cold Hardiness: Double Variegated Centaurea is moderately cold hardy and can withstand light frosts, making it an excellent choice for temperate climates.
Substrate: A well-drained and slightly fertile substrate is recommended. Centaurea prefers slightly acidic to neutral soils, but is quite adaptable and can thrive in poor soils.
Harvest: Centaurea Double Variegated flowers are ideal for cutting and use in floral arrangements. Cut the flowers when they are fully open to enjoy maximum beauty and longevity in the vase. To prolong flowering in the garden, cut off spent flowers regularly.
