Key growing notes

• Direct sow outdoors after the danger of frost has passed, planting 1 inch deep and 6–12 inches apart in well-drained soil.
• Soil temperature of 65–85°F supports optimal germination; keep the soil consistently moist until seedlings emerge.
• These sunflowers tolerate a wide range of soils but prefer well-drained soil with a pH of 6.5–7.5.
• Low maintenance and fast-growing, they are an excellent choice for the back of perennial borders or sunny beds.
• Consider bird netting to protect seeds during sprouting and guard large heads as they form.
