Helianthus F1 ‘Sunrich Gold’

Helianthus F1 'Sunrich Gold'

Trial: Annual

Years Trialed: 2003

Good Qualities:

Green centers (6); Great petal color (4); Pollenless (3); Overlapping petals, very good flower size, good foliage size, good gold, uniform height and timing; Well formed heads; Strong stem not too thick; Very strong, great eyelashes, thrips left it alone, very large head; Size, sturdy stem – I loved this one – And customers found it a nice change from brown center, while still having a typical showy sunflower image; Nice new color disc, same quality stem as ‘Sunrich Orange’, performed equally well in our direct seed trial in August; Market prefers black disc; Even, steady growth, will grow again, a nice sunflower; Nice size, blooms about 6 inches in diameter, heads were held upright on strong stems. I managed to get to these before the beetles could, customers liked these and bought them eagerly.


Lot of rust, light disk is main problem; When aged, has cobwebby, off-white, look of centers (loses green color); plants were nipped off by some little varment right at ground level; Only got one cut per plant, useful branching did not happen but we were quite droughty here all summer.


Similar to ‘Sunrich Orange’; Good single stem, a few axillary branches for bouquets; My customers chose these over all my other sunflowers, and they sold out before any others started moving; Will add to our farm mix next year, top trial at our farm for 2003; Have grown before, nothing too special for my market; The thrips love the ‘Sunrich Yellow’, but not the gold or orange; Began blooming 9/17 – about 2 months after seeding; We will be selling this, I really liked this one; One trialer’s results:
