Zinnia elegans (Common Zinnia)

Common Zinnia (Zinnia Elegans)


Common Zinnia (Zinnia elegans) is one of the most rewarding summer flowers with its brilliant colors and its profuse blooms over a lengthy season extending from early summer to frost. Adored by butterflies, they are also highly popular amongst gardeners thanks to their wide variety of plant heights, flower sizes, forms and colors - a diversity to suit every need!

  • Typically growing 1-3 ft. tall (30-90 cm) on upright, branching stems, they offer short varieties that are perfect for the front of the border and giants that look best in the middle or back of the border.
  • Flowers may be single with one row of petals leaving their center exposed, semi-double with several rows of petals still leaving the center exposed, fully double with several rows of petals hiding the center of the flower, or cactus-like with long petal whose edge rolls back along part of their length, giving the flowers a spiky look. As the flower matures, a circle of small golden stars surrounds its center disk.
  • Extremely easy to grow, Zinnias are annuals which love full sun and prefer a humusy, evenly moist and well-draining soil. Drought tolerant, they relish summer heat.
  • Wonderful plants for beds, borders, cutting gardens, containers, cottage gardens and they are unsurpassed as fresh cut flowers!
  • Don't crowd zinnias to keep them disease-free and avoid powdery mildew. Air circulation is important.
  • Among the easiest plants to grow from seed, you can start seeds indoors 4-6 weeks before the last frost date, should you wish earlier spring blooms.
  • Pinch young plants to promote compact and bushy shape. Deadhead spent flowers to encourage new blooms and maintain a neat appearance.
