In the garden

Stokesia laevis 'Blue Star' belongs to the genus Stokesia within the family Asteraceae and is native to the southeastern United States (including Louisiana, Mississippi, North Carolina, South Carolina, Alabama, Florida and Georgia). In the UK it reliably produces flowers between July and September, making it a mid- to late-summer perennial. Select a site with full sun or light afternoon shade; it will tolerate partial shade but flowers best with more sun. The plant prefers well-drained soils, especially sandy to loamy types, and does well in substrates that are acidic to neutral. Keep soil moist but avoid positions that remain waterlogged; good surface drainage is important. It is rated H7 — fully hardy in the UK — so plants may remain in the ground through winter in most locations. Stokesia laevis 'Blue Star' fits well at the front of mixed borders, in a sunny rock garden or planted in containers with free drainage. In containers use a loam-based mix and ensure pots have drainage holes to prevent standing water. Flowering from July to September provides a steady seasonal presence in sunny situations and container displays.
