Safety Overview
1.Centaurea Dealbata — Overview
Centaurea Dealbata, commonly known as Persian Cornflower or Whitewash Cornflower, is an exquisite perennial herb belonging to the Asteraceae family. Native to the Caucasus region, specifically Armenia, Azerbaijan, Georgia, Iran, and Turkey, it thrives in rocky slopes, open woodlands, and grasslands, adapting to a range of temperate conditions. This robust plant typically forms a bushy mound, reaching heights of 30 to 60 centimeters (12 to 24 inches) with a spread of similar dimensions, though it can occasionally grow taller.
Its distinctive foliage consists of deeply lobed, pinnatifid leaves that are silvery-green on the upper surface and often covered with a fine white tomentum (hairy coating) underneath, providing a striking textural contrast. The magnificent flowers, which bloom profusely from late spring through early summer, are large, thistle-like capitula, typically a vibrant fuchsia-pink or magenta with a contrasting creamy-white or pale yellow center, giving it the 'whitewash' moniker. Each solitary flower head is borne on sturdy, upright stems, attracting a host of pollinators.
Centaurea Dealbata is highly valued in horticulture for its ornamental appeal, drought tolerance, and ability to naturalize in suitable environments, making it a popular choice for borders, rock gardens, and naturalized areas. Its resilience and unique floral structure contribute significantly to garden biodiversity and aesthetic charm.

11.Centaurea Dealbata — Growing Guide
- ✓Climate and Hardiness — Centaurea Dealbata thrives in temperate climates, hardy in USDA Zones 3-8, tolerating cold winters and hot summers.
- ✓Sunlight Requirements — Prefers full sun exposure (at least 6 hours direct sunlight daily) for optimal growth and abundant flowering.
- ✓Soil Preferences — Requires well-drained soil; tolerates average to poor soil but prefers moderately fertile, neutral to slightly alkaline conditions.
- ✓Watering Regimen — Drought-tolerant once established, but benefits from moderate, regular watering, especially during prolonged dry spells and blooming periods.
