Also known as beach sunflower or cucumberleaf sunflower. Native to the Southeast and mid-Atlantic coast of the U.S. Grows 5 to 7 feet tall. Drought tolerant and salt tolerant, making it the perfect choice for a coastal garden or sandy soil.

When to Grow

Sow seeds outdoors after the last frost when soil temperatures are consistently above 60 F. In cooler climates, you can also start seeds indoors 2-3 weeks before the last frost for a head start. The plant matures in about 70-90 days​. 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

Direct sow seeds 1/2 inch deep, spacing them about 16 inches apart. For growing in containers, use a well-draining potting mix. Keep the soil moist during germination, which usually takes 7-14 days​.

How to Grow

As with all others, Ice Cream sunflowers thrive in full sun (at least 6 hours of direct sunlight daily). Water deeply but infrequently once established, to encourage deep root growth. Staking might be needed in windy areas​.

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.
