Details
The dark centers of Red Sun's 5-6 inch flowers are surrounded by glorious warm bronze-maroon petals that are yellow at the base. Slightly less intense red than Prado Red, it is also later, which extends the red sunflower season. The plants are 5 1/2-6 feet tall with 10 or more buds per plant. These are exceptional cut flowers with long stems, lasting up to 10 days in the vase.
