|Inca Series Marigolds produce early, fully double yellow, gold and orange flowerheads. In general, marigolds are robust, trouble free plants which branch vigorously. Leaves are finely divided, to 4 inches long, and medium green. Abundant pale yellow to orange blooms with large, dense collections of small petals from early summer to frost. Though thought of as a summer annual, works well for fall plantings too, especially as a chrysanthemum substitute. Great for borders and containers. A natural insect repellant for herb and vegetable gardens. Remove and discard spent flowers to encourage extended flowering and reduce "housing" for insects and disease.
