Easy Math:
basic information
Red Sun Sunflowers (Helianthus annuus) bring bold, vibrant color to any garden with their striking 5-6 inch blooms. Featuring deep red to burgundy petals surrounding a dark brown center, these annuals offer a dramatic contrast to traditional yellow sunflowers. Perfect for cut flower arrangements, they last up to 10 days in a vase. Red Sun attracts pollinators like bees, butterflies, and hummingbirds, while its seeds provide a late-season treat for birds. These sunflowers bloom from mid-summer to early fall, adding a stunning focal point to borders or beds.

How To Grow
GROWER TIP: Sunflowers develop long taproots, so it is best to use a loose sowing medium. They also do not transplant well, so if you decide to start some of your sunflowers indoors, we recommend using biodegradable CowPots. Direct sow in early spring when temperatures are at least 65°F.
