Estimated Native Range
Summary
Cheirolophus sempervirens, commonly known as Perennial Cornflower, is a perennial herb native to rocky areas and scrublands of Southwest Europe, including the Iberian Peninsula and the Mediterranean region. This plant typically grows to a height of 3-5 feet (0.9-1.5 meters) and a width of 3-4 feet (0.9-1.2 meters), featuring a bushy habit with lance-shaped, green leaves. The flowers are particularly showy, with a vibrant display of purple and pink blooms that appear in the spring and continue through summer and into fall, attracting pollinators such as bees and butterflies.
Perennial Cornflower is valued for its long flowering season and its ability to thrive in poor soils, making it a suitable choice for rock gardens, borders, and wildflower meadows. It is drought-tolerant once established, requiring low to medium amounts of water, and prefers well-drained soils in full sun. While it is not commonly known for any significant diseases or pests, it is important to avoid overwatering to prevent root rot. Due to its potential for invasiveness, it is crucial to consult local guidelines before planting Cheirolophus sempervirens outside its native range to ensure it does not pose a threat to local ecosystems.CC BY-SA 4.0
