Plant Profile
Earthwalker Sunflowers (Helianthus annuus Earthwalker) are a captivating variety of sunflowers known for their unique combination of colors and striking appearance. These sunflowers typically grow to heights of about 5-8 feet, with flower heads reaching 5 to 7 inches in diameter. The petals of Earthwalker Sunflowers display a stunning array of warm earthy tones, ranging from rusty reds and deep oranges to golden yellows, reminiscent of a sunset or the colors of the earth. The contrasting dark centers add to their visual appeal, making them a standout feature in garden beds, borders, or floral arrangements.
Soil pH
Earthwalker Sunflowers thrive in well-draining soil with a pH no higher than 6.5. They are adaptable to various soil types, including loamy and sandy soils, as long as the soil is fertile and enriched with organic matter.
Sun Requirements
As sun-loving plants, Earthwalker Sunflowers require full sun to thrive. Plant them in an area that receives at least 6 to 8 hours of direct sunlight per day for optimal growth and flowering. Insufficient sunlight may result in reduced growth and fewer blooms.
Watering Requirements
While Earthwalker Sunflowers are relatively drought-tolerant once established, consistent watering is essential, especially during the early stages of growth and during hot, dry periods. Water deeply and evenly, ensuring the soil is consistently moist but not waterlogged. Allow the soil to dry slightly between waterings to prevent root rot. Applying a layer of mulch around the base of the plants can help retain moisture and regulate soil temperature.
Best Plant Hardiness Zones
Earthwalker Sunflowers are well-suited for planting in USDA hardiness zones 4 to 9. These zones provide the ideal climate conditions for sunflowers, with warm Summers and sufficient growing seasons. In these zones, Earthwalker Sunflowers can thrive and produce an abundance of stunning blooms throughout the Summer months.
Additional Tips
Beautiful cut flowers: These late-season blooms echo the shades of Fall. Cut for flower arrangements while blooms are at or almost at their fullest.
Feed the birds: Once the flowers have bloomed and faded, leave the seed heads for your local birds. Goldfinches, cardinals, chickadees and jays love sunflower seeds.
Fertilize sparingly: Earthwalker Sunflowers do not require heavy fertilization but can benefit from a balanced fertilizer applied during the growing season to promote healthy growth and vibrant blooms.
Provide support if needed: While Earthwalker Sunflowers are generally sturdy, providing support such as stakes or cages may be necessary to prevent bending or toppling. You can also plant these sunflowers along a wall or fence.
With their rich earthy tones and striking appearance, Earthwalker Sunflowers add warmth and beauty to any garden or landscape. With proper care and attention to their soil, sun, and watering requirements, these sunflowers can thrive and become a stunning focal point in any outdoor space.
