Helianthus ‘Orange Glory’

Trial: Annual

Years Trialed: 2007

Good Qualities:

Nice color (2); Good head size (2); OK sunflower; Single stem, later to bloom, nice disc size; A nice sunflower, but…; Very tall – so can cut at the needed length; Very drought tolerant, tolerant of severe weather (wind and hail damage); Standard orange cultivar; Excellent sunflower, this is probably going to be among our favorites, very uniform days to harvest- cut all of them in about 8-9 day span, beautiful flowers can cut tight and they open very nice! Did well mid and late (Oct.) season; It did compare to Sunrich Orange and was a little earlier, flowers held well and it was really difficult to tell the difference between this one and Sunrich orange; Great color and form – pollenless – very stout stems – nice height, quick to flower – all came on at once! Excellent vase life! Customers loved!; Classic sunflower – petals are nicely pointed; Nice form, strong neck and stem, good neck posture, perfect height; At each planting an equal amount of ‘Sunrich Orange’, ‘Tosca’ and ‘Orange Glory’ were direct seeded – although the seed of ‘Sunrich Orange’ was over a year old it germinated better than either of the two trial cultivars in all four sowings, during the growth phase all three were indistinguishable. However, at flowering ‘Tosca’ flowered approximately 5-7 days earlier than ‘Sunrich Orange’ at all planting dates. ‘Orange Glory’ flowered at the same time as ‘Sunrich Orange’ at all planting dates. The marketable flowers could not be distinguished by cultivar. In fact ‘Orange Glory’ and ‘Sunrich Orange’ are similar. They could not be identified as separate cultivars; Classic color.


None (3); Slightly shorter plant height (3) – can be an issue for large field production- need to bend for harvesting; Not a stand out; It bloomed on the same schedule as Pro Cut Orange, which is better in every way — thicker stems, more substantial petals. – also, it got too tall as the days lengthened, and took longer to bloom than Pro Cut Orange; Prone to insect leaf damage; Strongly daylength sensitive: Long day plants flowered at 74 days from sowing, 3 weeks later than the short-day treated plants – stem length difference: long day 46 in., short day 28 in.; Some had deer damage, some were attacked by the “Midge”???; I experienced an increase in insect problems over other sunflower cultivars; Insects- All came at once!; Rock-like debris in seed packet; A bit later than the others in our trials.

Similar Cultivars:

‘Sunrich Orange’ (5); ‘Sunbright’ (2); Probably closer to ‘Orange Glory’ than ‘Sunrich Orange’ in flower color; Seemed like ‘Procut’; ‘Tosca’ is 5-7 days earlier ‘Orange Glory’ is not different from ‘Sunrich Orange’ in habit and time of flowering.


It flower slightly shorter and few days earlier than ‘Sunrich Orange’, came into 50% flowering on approximately 5/24/07 (planted on 3/9/07, zone not specified), pollenless flower; Send back to breeder for more work; Nothing special. For me- it was just another sunflower – trends are changing in this area- large sunflowers as well as small flowered sunflowers are selling well, Procut sunflowers harvested before ‘Orange Glory’; In short days, plants short and with profuse flower bud formation on upper nodes, so production should be limited to summer (long day) conditions; I am very impressed and I try a lot of sunflowers, uniform like Procut Orange but a nice flower, comes in just after Sunrich Orange, and with Tiffany- but they all come on together, not like Tiffany which seems to go on for a couple of weeks; I would like to try more of this one next year and really compare it with Sunrich Orange, it’s hard to tell with 1,000 seeds – we do 40,000 Sunrich Orange a year so I would like to try 15,000 and see how they stand up to Sunrich Orange; Center seems to develop quickly even before petals unfold? – smaller than sunbright; Perfect compliment with ‘Sunrich Orange Summer’ for weekly plantings for bouquets; I liked the similarity of the three cultivars. By having ‘Tosca’ flowering earlier gave me flexibility in harvesting to meet my markets.


Cut when petals are ready to open (before the bees get to pollinate), we also remove all leaves. See separate postharvest report for results from NC State University postharvest evaluations.
