A must-have for any sunflower lover, Red Sun’s vibrant, bronze/maroon petals are offset by dark centers, creating a unique statement in the summer garden. Blooming a little later in the summer and growing to be about 5-6’ tall, this Sunflower extends the bloom season with a splash of vibrant color. Red Sun is a fantastic cut flower, often lasting up to 10 days in a vase. Bonus: bees, butterflies and hummingbirds love this easy-to-pollinate variety!

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
