Helianthus annuus
Tuscan Classic Sunflower Seeds (Helianthus annuus) This vigorous sunflower bears large golden flowers with dark centres on tall stems. Plan this variety for an ornamental bed, border, or suitable container, according to its mature size and growing requirements. Adjust watering to rainfall, wind, container size, and the actual moisture at soil level. Good air circulation and adequate spacing help foliage dry normally after rain or irrigation.
Direct sow after the last frost; avoid disturbing the roots. Sow about 1.3 cm deep. Keep the seedbed evenly moist through emergence. Allow 45 to 60 cm for branching types. Provide full sun and avoid standing water. A germination temperature of 21 to 24°C is appropriate for this crop. Thin crowded seedlings early and harden indoor-started plants gradually before transplanting.
Follow the packet's guidance for the appropriate cutting or harvest stage. Tuscan Classic Sunflower is suited to beds, borders, or containers where its form and flowering can be appreciated. Pair it with plants that prefer comparable light, moisture, and drainage. Water regularly at soil level during establishment and flowering. Keep the planting accessible for observation, watering, harvest, or grooming. Use clean tools, remove damaged material, and store unused seed in a cool, dry, dark location. Choose compatible neighbouring plants and maintain enough room for air circulation.
