Spring is the best time to plant marigolds. Marigolds can germinate quickly and do not need sunlight until after the seeds germinate and sprout. They will bloom in abundant sunlight for about eight weeks after being planted. It takes 7 to 14 days for the plant to sprout after planting the seeds.
The most common type is the French marigold, also known as Tagetes patula. It has fern-like leaves and flowers ranging from yellow to orange to red. French marigolds typically grow to a height of 10 to 12 inches.
Another common variety is the African marigold or Tagetes erecta. They are taller than the French marigold and have larger leaves. It has large, ruffled, and almost pompom-shaped flowers, with colors ranging from yellow to orange. Typically grows reaching 12 to 20 inches tall.
