NC State Extension

Helianthus ‘ProCut Bicolor’

Trial: Annual

Year Trialed: 2004

Year of Trial: First (from 2004 report)

Good Qualities:

Beautiful bi-color (8); Mixed well or by itself, strong stems, well accepted; Strong-stemmed dark colored sunflower, a welcome break from the usual weak-necked darker introductions; Favorite new sunflower, quick crop time; Best bi-color I’ve grown, very uniform production; Flower coloration distinctive, useful for fall bouquets, fast, nice size, consistent, flowers and height plant; Nice petal formation, strong stem, but not too thick, nice head size; Two weeks earlier than ‘Ring of Fire’; Nice flower size.


Drops petals readily in postharvest (2); No problems (2); Stems are very thick! A lot of market customers did not like this, too big for florist use. I would not grow again because of this; Poor germination; Coloration – brownish red; color fades in bright sunlight, final coloring faint; Opens fast and turns sideways, color could be a more contrasting bi-color like ‘Orange Mahogany’; Weak stems, floppy flower heads.


Used Floralife; Did not use any postharvest treatment; Did not refrigerate; water only. Editor’s note: see separate postharvest article in this issue for more information.


Similar to ‘Terra Cotta’, ‘Ring of Fire’, and ‘Orange Mahogany’; One of the better of a 10 varieties tried; Not particularly good, contrast of colors; Will definitely grow again; Good single stem.
