Helianthus annus - Sunflower Florenza
Pot size: Deep 4 inch, 6 pack
The Florenza variety of sunflower has chocolate centers with mahogany petals and yellow tips. The 4 to 5 inch blooms are produced on sturdy stems from multi-branched plants, making them ideal for cut flowers. They have relatively low pollen for a longer vase life. Great for pollinators with a subtle chocolatey fragrance.
Annual ornamental
Days to maturity: 70 - 80 days
Size: Grows 3.5 to 5 feet tall.
Water: Medium (heavy feeder; will suck nutrients from other surrounding crops)
Sun: Full sun (6+ hours daily); very heat tolerant
Other Notes and Uses: Will continue to bloom from summer into early fall. Removing the main stem when the plants are 12- 18 inches tall will encourage side branches with long stems. while the plant is bushier and shorter, pinching will delay flowering by one to two weeks.
