- Life cycle
The life cycle of 'Earthwalker' sunflower (Helianthus annuus 'Earthwalker') starts with seed germination in warm soil, usually occurring in spring or early summer when the soil temperature reaches at least 50-60 degrees Fahrenheit. Upon germination, the seedling emerges and develops its first true leaves, after which it enters a vigorous vegetative growth phase characterized by rapid stem elongation and leaf development. In the reproductive stage, the plant forms a thick stalk and a flower head that can reach several inches in diameter, displaying a variety of colors from deep red to burnt orange. Pollination occurs predominantly through insect activity, particularly by bees, leading to fertilization and subsequently, seed development within the flower head. As the plant matures, the flower head dries out and the sunflower seeds become ripe, at which point they can be harvested for consumption or replanted. After seed dispersion or harvest, the annual plant completes its cycle and typically dies, leaving behind seeds to continue the species in the next growing season.
- Propogation
Propogation time
Spring to early summer
Propogation: The Helianthus annuus 'Earthwalker', commonly known as the Sunflower 'Earthwalker', is a variety favored for its deep, warm hues which can range from yellow to deep red-brown. The best time to propagate the Earthwalker sunflower is in late spring after the last frost when soil temperatures have reached at least 50°F (10°C), promoting optimal germination and growth. The most popular method of propagation for this sunflower is by direct seeding in the garden. To propagate by seed, find a sunny location with well-draining soil. Plant the seeds about 1 inch (2.54 cm) deep and space them about 6 inches (15.24 cm) apart to allow the seedlings ample space to grow. Water gently but thoroughly after sowing to encourage good soil-seed contact, and keep the soil moist until germination, which typically occurs in 7 to 14 days. Thin the seedlings to about 18 to 24 inches (45.72 to 60.96 cm) apart as they grow to ensure they have enough room to mature. The Earthwalker sunflower will generally reach maturity and flower in late summer to early fall, depending on the local climate.
