Description

(Zinnia elegans). This zinnia is a real showstopper with its deep blood-red blooms that reach 4 to 5 inches across and come packed with double petals. Benary's zinnias are top-notch, with flowers that are bigger, more uniform, and just plain stunning. A classic zinnia from Benary Seeds, a renowned company founded by Ernst Benary in Erfurt, Germany, in 1843.

Growing Tips: Benary's Giant Deep Red zinnias thrive in full sun and nutrient-rich, well-draining soil. Regular deadheading and pinching early on encourage a bushier growth habit and increase the number of flowers you'll see throughout the season.

When to Grow

Start seeds indoors 4 weeks before the last frost or sow directly outdoors after the risk of frost has passed. In the U.S., this is typically late spring​; however, we recommend checking your local frost dates for a specific planting time. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds about ¼ inch deep, spaced 9 to 12 inches apart, to give enough room for air circulation and reduce disease risk. Zinnias germinate quickly, in 4 to 6 days under warm conditions. If starting indoors, use biodegradable pots or other means to minimize root disturbance when transplanting​.

How to Grow

Water deeply but let the soil dry slightly between waterings. These zinnias perform well with light fertilization and tolerate heat, so regular maintenance is simple. Deadheading prolongs the blooming period through summer​.

How to Save Seeds

  • Allow the flowerhead containing the seeds to mature and dry on the plant.
  • Clip off the flowerhead and place it in a paper bag or other container.
  • Working over the top of another clean, opened container, rub the flowerheads between the palms to break them apart.
  • The seeds can be separated from the chaff by first screening and then winnowing.
  • Store in a cool, dry, dark place over winter.
