Zinnias
- Zinnias are hardy annuals with bright, showy heads of yellow, orange, and red.
- They prefer warm, average soil and night temperatures above 50°F (10°C).
- They thrive in full sun and will even tolerate dry conditions.
- Plant seeds ¼ inch (6 mm) deep and 3 to 5 inches (8 to 13 cm) apart.
- They will grow to a height of 20 inches (50 cm).
- Thin the seedlings to 6 to 10 inches (15 to 25 cm) apart for show plants.
- This plant is a hybrid, so don't save the seeds, or they will produce inferior plants next year.
- Buying new zinnias each year will keep your garden looking its best.
