Special Instructions: For the straightest stems, stake plants, especially in windy, rainy, or part-sun areas. If fall planting in mild climates with winter precipitation, plant in raised beds or containers to ensure good drainage. For longest vase life, cut flowers when 1/3 of the flowers are open on a stem, and remove most of the foliage. Row covers at sowing or transplanting help prevent flea beetles.
Special Care: Light aids germination; do not cover seeds with soil.
