These multi-branching plants reach 4 to 5 feet tall and spread about 2 to 3 feet. The blooms reach 5 to 6 inches across. Get the pollinator party started with this All America’s Select Award winner.

Growing Tips: Ring of Fire sunflowers prefer full sun, well-drained soil, and consistent watering early in growth. Their multicolored petals attract pollinators and provide a vivid centerpiece in cutting gardens. Pinch young plants to encourage branching and more blooms. Staking may be needed in windy locations due to their height and branching habit.

Growing Guide

When to Grow

Sow seeds outdoors after the last frost, when soil temperatures are consistently above 60°F. In cooler climates, start indoors 2–3 weeks before the last frost date to get a head start. 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

Choose a sunny location with fertile, well-draining soil. Sow seeds 1/2 to 1 inch deep and space them 12 to 18 inches apart. Water gently but thoroughly. Thin seedlings to the strongest individuals once they reach 3 inches tall.

How to Grow

Water deeply 1–2 times per week depending on weather and soil conditions. Apply a balanced organic fertilizer monthly to support flowering. Deadhead early blooms to extend the flowering season. Support tall plants with stakes or grow along a fence to prevent lodging.

How to Save Seeds

  • When petals die back and heads begin to dry and turn brown, place a paper bag over the heads to protect seeds from birds.
  • After a few days, the heads will dry to a dark brown. Bring the heads indoors and hang them upside down in a dry area in direct sunlight for up to a week, shaking seeds free each day.
  • Store seeds in a cool, dark, dry place.
