They also give gardeners season-long blooms of fragrant flowers and even leaves unlike other varieties with pungent odor. Tagetes tenuifolia is also easy to grow, deer & rabbit resistant, and drought tolerant.
The French Marigolds (Tagetes patula) characterized by a bushy, compact size. Don’t let that fool you; tagetes patula’s elegant, dainty, demure flowers and plants growing anywhere from 6 inches to about 2 feet tall. French marigolds require full sun and a well-drained soil. They need to be planted deeper than the bedding container and six to nine inches apart from the other French marigolds seeds.
Desert marigold known for its daisy-like flower petals reaches from a few inches up to a foot high. Although it serves as a short-lived perennial, this plant of yellow flowers produce lots of marigold seeds.

African marigolds also bear the name American marigolds or Aztec marigolds. The African marigold produces blooms of larger flowers. Among other well-known varieties like the French marigolds, this Tagetes erecta is more drought tolerant, loves the full sun, and seem to like a poor soil.

Marigold Plant Care: Question & Answers
Question: Some gardeners suggest that marigolds will keep aphids away from other plants. Is this true? HZ, Illinois
Answer: If the weather is favorable for aphids I’m not sure anything except constant spraying will repel them.
For example, pyrethrum spray made from flowers of the chrysanthemum family is an effective control for aphids.
Yet aphids attack the chrysanthemum plants. A bench of marigold plants in the greenhouse has no effect as a deterrent to aphids on plants in adjoining benches.
