Good Qualities
Uniform (6); Nice color (6); 7 to 10 days earlier than ‘Sunrich Orange’ (2); Easy to grow (2); A nice addition to the Sunrich series (2); Appearance great for retail florist arrangements; Not too tall, nice petal shape; Same great quality as ‘Sunrich Orange’; 4 to 5 inch blooms with orange-gold petals and small dark center, pollen-free, some secondary branching not useful; Classic sunflower; Long vase life, the first of all my sunflowers (‘Sunbright’, ‘Procut’, ‘Sunrich’) to bloom; Sturdy stem, quick to bloom, overlapping petals and attractive bloom; Big flowers, easy to work with! perfect height!; Not significantly different than other Sunrich cultivars, but we really liked the brown unopened disc flowers; Bloomed 60 days from seeding; Size of head, and height; Under summer growing conditions, performed well, producing strong stems and large, attractive heads (7.5 cm disk diameter), about 4 to 7 days before ‘Sunrich Orange’.
Problems
None (2); Not as early as ‘Procut Orange’; Stems less thick than other sunflowers, flowers smaller – We just like others better, erratic germination; Too big and clunky and stems too thick, maybe with tighter spacing would be better, I would like more double – lose one petal and it is compost, planted with #22 Gardenway seeder like all my other sunflowers- they didn’t get so chunky; Small bloom size; Some erratic opening of ray flowers – non uniformity; Had some rabbit damage, why the yield was low – I row cover sunflowers to keep rabbits out, this is troublesome; Like ‘Sunrich Orange’, this variety is photoperiod sensitive, flowering 19 days earlier under short day conditions than if treated by long days in the seeding stage, with much shorter plants and smaller flowers (disk diameter 3.8 cm) – so if you want an early crop of sunflowers in a tunnel, this one will be too short and small to be attractive. The photoperiod treatments were applied by exposing the seedlings to either 12 hrs. or 16 hrs. in the first three weeks after emergence, then planting the seedlings to the field.
Similar Cultivars
‘Sunrich Orange’ (3), ‘Sunbright’ and ‘Solara’; ‘Pro-cut’, which survived the frost!
Postharvest
Cut just when petals are starting to lift and unfurl from bud; Clean, cold water; Little preservative, lots of water; I cut all my sunflowers into warm water with Chrysal Professional #2 solution and let them sit for 6-8 hrs, then they go into the cooler. Note: Check out the separate postharvest article in this issue for more information on postharvest vase life and treatments.

Comments
Stem length disappointed – definitely climate related; A viable commodity to compliment ‘Sunrich Orange’, the finding of consistent quality in the later seeding is contrary to the recommendation from breeder, who said that it was suited to long day production only; Could harvest one longer stem, or cut first, shorter stem with good development of side shoots; My florists love local sunflowers because of how they last and no shipping damage, my farmers market customers can’t believe how long they last; You can’t go wrong with sunflowers! Everyone loved them!; Although this was billed as 10 days earlier than ‘Sunbright’, they bloomed in the same day for me, both grow in unheated high tunnel; I will probably try more of this throughout the season to get a true feel from customers if they like it or not; Seeded directly to a 128 cell tray 4/20/06, harvest period 6/21-7/8; I like how they didn’t all bloom on the same day, nice color.
