HELIANTHUS Annuus Grey Stripe (Sunflower, Grey Stripe) is a variety of the common sunflower. It is characterized by its distinctive grey-colored seeds and striking appearance.
'Grey Stripe' Sunflower is a tall annual plant that typically grows to a height of 5 to 10 feet (1.5 to 3 meters) and spreads about 2 to 3 feet (60 to 90 cm) wide. It has thick, sturdy stems and large, rough-textured leaves. The plant produces a single large flower head at the top of each stem.
The flower head of 'Grey Stripe' Sunflower is the focal point of this variety. It is composed of numerous individual flowers, each with a dark brown center known as the disc florets and surrounding yellow ray florets. The flower heads are typically large, reaching up to 12 inches (30 cm) in diameter.
The seeds of 'Grey Stripe' Sunflower are the distinctive feature of this variety. They have a greyish or blackish color with white stripes, hence the name "Grey Stripe." The seeds are larger than those of other sunflower varieties and are often used for culinary purposes or as bird feed.
'Grey Stripe' Sunflower typically blooms in summer, from mid to late summer, depending on the specific growing conditions and climate. The flowering period can last several weeks, providing a burst of color and attracting pollinators to the garden.

Additionally, the mature seeds are highly appealing to birds, making this variety a great addition for bird-friendly gardens.
'Grey Stripe' Sunflower thrives in full sun and well-drained soil. It is relatively adaptable to different soil types but prefers fertile, loamy soil. Regular watering is needed, especially during dry periods, to support healthy growth and flowering. The tall stature of this sunflower variety may require staking to prevent the stems from bending or breaking under the weight of the flower heads.
'Grey Stripe' Sunflower is typically grown from seeds. Sow the seeds directly into the garden soil after the danger of frost has passed, or start them indoors a few weeks earlier and transplant the seedlings outdoors. Provide adequate spacing between plants to accommodate their size. The plants will benefit from regular watering, especially during dry spells, to support healthy growth and flowering.
