The Mammoth Sunflower (Helianthus annuus ‘Mammoth’) is a variety of sunflower known for its impressive size and large flower heads. Here are some key features and characteristics of the Mammoth Sunflower:
Size: As the name suggests, Mammoth Sunflowers are known for their exceptional height and large flower heads. They typically grow to towering heights of around 8 to 12 feet (2.4 to 3.7 meters), though some specimens may reach even greater heights under optimal growing conditions.
Flower Heads: Mammoth Sunflowers produce massive flower heads that can measure up to 12 inches (30 centimeters) in diameter or more. The flower heads consist of a central dark brown or black disc (disc florets) surrounded by bright yellow petals (ray florets), creating a striking and dramatic appearance.
Growth Habit: Mammoth Sunflowers have an upright growth habit, with sturdy stems that support the weight of the large flower heads. The tall, robust plants make a bold statement in the garden and are often used as focal points or background plantings in landscapes.
Blooming Period: Mammoth Sunflowers typically bloom in mid to late summer, producing an abundance of cheerful flowers that attract pollinators such as bees, butterflies, and birds. The long blooming period adds seasonal interest to the garden and provides a valuable food source for wildlife.
Cultural Requirements: Mammoth Sunflowers thrive in full sun and well-draining soil. They are relatively low-maintenance plants and are tolerant of a wide range of soil types and growing conditions. Regular watering, especially during dry periods, can help promote healthy growth and flowering.
Versatile Use: Mammoth Sunflowers are versatile and can be used in various garden settings, including flower beds, borders, and cutting gardens. They make excellent cut flowers for floral arrangements and bouquets, adding a bold and cheerful accent to indoor spaces.
Seed Production: Mammoth Sunflowers are also valued for their large seeds, which can be harvested for snacking, bird feed, or seed saving. The seeds are rich in protein and nutrients, making them a popular choice for human consumption and wildlife feed.
