4 Foot Tall Multi-Bloom Bi-Coloured Sunflower

This sunflower grows about 4 foot tall on a sturdy stem. It produces 3 inch blooms in a nice dark red and medium yellow that fades with age. The flowers get this nice crackled look that looks great. I havent cut any so I am not sure how it does as a cut flower. All in all if you like the colour of this sunflower than I Highly recommend it as it grows well and isnt very tall.
