We love to grow zinnias. This Mexican, annual flower creates loads of color from mid summer to fall and is a magnet for pollinating bees and butterflies.
There are many types of zinnias. Most fall in the Zinnia elegans species. They range from a few feet tall to 5 feet tall. We like the old fashioned 'State Fair Mix' and 'Benary Giants' for big, gaudy, colorful flowers. If powdery mildew is an issue in your garden try the 'Oklahoma Series'. If you're looking for shorter zinnias, check out the 'Profusion' and 'Zahara Series'. These have white, pink, red and yellow selections on 1 foot tall, mounding plants that flower all summer. They're great in the front of a border or in containers.
Zinnias come in different flower shapes as well. The cactus flowered zinnia has long, curved and twisted petals, like a chrysanthemum, on 3 foot tall plants. The newer 'Queeny Series' features a mix of colors, such as orange and lime or red and lime, with 3 inch diameter flowers. The blooms are semi double and make great cut flowers.
If you're looking for a more wild zinnia, try the Zinnia haageana species. Known as the Mexican zinnia, this 2 foot tall plant produces small, colorful, double blooms. 'Persian Carpet' and 'Jazzy Mix' are favorites for us.
Start zinnia seeds indoors about 1 month before transplanting into the garden to get a jump on the season. Don't rush to transplant as they like the warmth. Give them plenty of room to grow, especially the large flowered types. You can top them when small to induce bushier growth.
