Botanical Information

• Scientific Name: Tithonia rotundifolia
• Common Names: Mexican Sunflower, Tithonia
• Family: Asteraceae

Plant Characteristics

• Growth Habit: Mexican sunflower is an annual that grows rapidly, typically reaching heights of 4-6 feet (1.2-1.8 meters), though it can grow taller under ideal conditions. It has a bushy, upright growth habit.
• Leaves: The leaves are large, coarse, and dark green, with a slightly hairy texture. They are broadly ovate and can grow up to 6 inches (15 cm) long.
• Flowers: The flowers are large, daisy-like, and vibrant orange or red, measuring 3-4 inches (7-10 cm) in diameter. They are borne on long, sturdy stems and have a central disc that attracts numerous pollinators.
• Blooming Season: Blooms profusely from midsummer to the first frost, providing continuous color and interest in the garden.

Growing Conditions

• Climate: Mexican sunflower is well-suited to warm climates and is hardy in USDA zones 5-10. It thrives in summer heat and is relatively drought-tolerant once established.
• Sunlight: Requires full sun for optimal growth and flowering. It needs at least 6-8 hours of direct sunlight per day.
• Soil: Prefers well-drained soil with moderate fertility. It can tolerate poor soils but performs best in slightly acidic to neutral pH soils.
• Water: Needs regular watering to establish but can withstand dry conditions once mature. Overwatering should be avoided as it prefers moderately dry soil conditions.

Planting and Care

• Seed Starting: Seeds can be sown directly in the garden after the last frost. For earlier blooms, start seeds indoors 6-8 weeks before the last expected frost date. Seeds germinate quickly and easily.
• Transplanting: Transplant seedlings outdoors when they have several true leaves and the danger of frost has passed.
• Spacing: Space plants about 2-3 feet (60-90 cm) apart to allow for their large size and to promote good air circulation.
• Pruning: Minimal pruning is required, but removing spent flowers (deadheading) can encourage continuous blooming and prevent the plant from becoming too leggy.
• Fertilization: Fertilization is generally not necessary, but a light application of compost at planting time can promote healthy growth.

Benefits and Uses

• Ornamental Value: Mexican sunflower’s vibrant flowers and tall stature make it an excellent choice for borders, backdrops, and cutting gardens. It provides a bold, colorful display that attracts attention.
• Pollinator Attraction: The flowers are highly attractive to butterflies, bees, and hummingbirds, making it a valuable addition to pollinator gardens.
• Cut Flowers: The long-stemmed flowers are ideal for cutting and can be used in fresh flower arrangements.
• Drought Tolerance: Once established, Mexican sunflower is drought-tolerant, making it a good choice for low-water gardens.

Cautions

• Self-Seeding: Mexican sunflower can self-seed prolifically. To prevent unwanted spreading, deadhead spent flowers before seeds mature.
• Height Considerations: Due to its height, it may need staking or support in windy locations to prevent the stems from breaking.

Mexican sunflower (Tithonia rotundifolia) is a vibrant and easy-to-grow annual that brings bold color and height to gardens.
