ëPolaris is a shasta daisy cultivar that typically grows 2-3 (less frequently to 4) tall. It is noted for its unusually large single blooms (4-6î diameter) with white rays and yellow center disks. Multiple flowers per stem. Coarsely-toothed, lance-shaped, medium green leaves (basal leaves to 12î long). Blooms most of the summer. Excellent and long-lasting fresh cut flower. Formerly included in the genus Chrysanthemum.
- Full sun to part shade
- Dry to medium
Easily grown in average, dry to medium, well-drained soils in full sun. Good drainage is essential. Wet soils in winter can be fatal. Tolerates some light shade, particularly in hot summer climates. Remove spent flower heads to promote additional bloom. Divide clumps as needed (every 2-3 years) to maintain vigor. Plants are somewhat short-lived. Consider cutting stems back to basal leaves after flowering to preserve plant energies and perhaps prolong plant life. Plants may be grown true from seed.
