Zinnias are one of the easiest flowers to grow from seed. They bloom in bright colors like pink, red, purple, orange, yellow, lavender, white, and green. Zinnias grow fast and are usually 1-2 feet tall. Zinnias are annuals and need to be replanted each planting season.
Plant zinnia seeds in the ground 1/4 inch deep and 4-24 inches apart after the last frost. It is recommended that you plant zinnia seeds directly in the ground because zinnias do not do well when they are transplanted. However, if you would like to start them indoors, make sure you transplant when they are very young. It takes about 60-70 days for zinnias to bloom. Zinnias need full sun to grow. Zinnias represent friendship and look great in flower bouquets!
