ABOUT

The 'Choco Sun' sunflower is a striking plant notable for its richly colored flowers. This particular variety features a distinctive flower head, comprising a dark brown, almost chocolatey central disk that stands in bold contrast to the vibrant yellow petals surrounding it. The petals have a classic sunflower shape, broad and mildly pointed at the tips, radiating outward from the center like the rays of the sun. The central disk, where the seeds will eventually develop, is made up of smaller individual flowers that can attract bees and butterflies. The foliage of 'Choco Sun' is typically green, with leaves that can have a slightly rough texture. The leaves are heart-shaped, sometimes with serrated edges, providing a lush backdrop for the striking blooms that sit on top of sturdy stems. Overall, the coloring of this sunflower variety is reminiscent of chocolate, giving it a warm and inviting appearance that can add a touch of brightness to any garden setting.

Pruning
  • water dropWater

    Sunflowers, specifically the 'Choco Sun' variety, require deep watering about once a week, ensuring that the soil is thoroughly moistened. This typically translates to about 1.5 gallons per watering for outdoor plants, depending on weather conditions. It’s important to avoid over-watering, which means allowing the soil to dry out slightly between watering sessions. During hot or windy weather, the plants may need additional water, and potted sunflowers might require more frequent watering, about two to three times per week, due to the limited soil volume.

  • sunLight

    Sunflowers, including the 'Choco Sun', thrive in full sun exposure, requiring at least 6 to 8 hours of direct sunlight daily. They grow best in locations where they receive unfiltered sunlight for the majority of the day. A spot that gets early morning light is ideal as it helps the plant's leaves dry out quickly, reducing the chances of fungal infections.

  • thermometerTemperature

    Sunflowers, like 'Choco Sun', perform well in warm conditions and can tolerate temperatures as high as 90°F or higher. They can survive a minimum temperature of 34°F but frost can damage them. The ideal temperature range for optimum growth is between 70°F and 78°F.

  • scissorsPruning

    For sunflowers like 'Choco Sun', pruning is generally not necessary as they are annual plants. However, removing any dead or damaged leaves and spent flowers can encourage further flowering and help maintain plant health. Pruning should be done as needed throughout the blooming period, primarily to enhance appearance and plant vigor.

  • broomCleaning

    As needed

  • bambooSoil

    Sunflowers, such as 'Choco Sun', thrive best in well-draining soil with a pH between 6.0 and 7.5. A good soil mix for these sunflowers would be a blend of loamy garden soil, compost, and a bit of sand to improve drainage. It's crucial to ensure the soil is rich in nutrients, so incorporating aged manure or a slow-release fertilizer will support their growth.

  • plantRepotting

    Sunflowers like 'Choco Sun' are typically grown as annuals and do not require repotting. They are planted directly into the ground or outdoor containers where they will grow for the season and then die after blooming and producing seeds.

  • water dropsHumidity & Misting

    'Choco Sun' sunflowers are quite adaptable and do not require specific humidity levels; average outdoor conditions are suitable. These plants are tolerant of both humid and dry atmospheres as long as their soil moisture needs are regularly met.

  • circleLife cycle

    The common name for Helianthus annuus 'Choco Sun' (PBR) is the 'Choco Sun' sunflower. The life cycle begins with seed germination, typically in the spring after the last frost when the soil has warmed. Seedlings emerge and grow into young plants with a central stem and leaves, relying on sunlight and water to undergo photosynthesis and grow. As the plant matures, it develops a bud that unfolds into a large, typically yellow flower with a dark brown center, attracting pollinators. Following pollination, the flower head matures into a seed head containing numerous seeds. The plant completes its life cycle by senescing and dying back, usually after seed dispersal in late summer or early fall, with seeds capable of overwintering to begin the next generation.

      Spring-Early Summer

    • The Helianthus annuus 'Choco Sun', commonly known as the 'Chocolate Sun' sunflower, is typically propagated through seeds. Propagation by seeds is the most popular method for this plant and is generally done in the spring after the last frost when soil temperatures reach around 70 to 85 degrees Fahrenheit (21 to 29 degrees Celsius). To propagate 'Chocolate Sun' sunflowers, seeds should be sown directly into well-drained soil, at a depth of about 1/2 inch (1.27 centimeters), spaced 6 to 18 inches (15 to 46 centimeters) apart to allow adequate room for growth. The plants need a full-sun location to thrive. Regular watering is needed until the seedlings are well-established, and in 7 to 10 days, germination will usually take place, leading to the development of a hardy and vibrant sunflower suited to a range of garden settings.
