This graceful Mexican annual finds a sale in the young stage for bedding-out purposes in early summer. It grows about 3 ft. high, has finely divided leaves, and bright rose, purple, or white flower heads, freely produced in warm seasons. It is easily raised from seeds sown in gentle heat in March, the young plants being hardened off for sale by May in small pots or boxes.
