Zinnia ‘Oklahoma Pink’

Trial: Annual

Year Trialed: 2008

Good Qualities

Productive (11); The pink color is a true cotton candy pink (5); Plant withstands wind better than larger zinnias, good stem length, dependable; Straight stems, overall very uniform petal layerage; Nice range of pink colors in small flowers is popular with both designers and customers; Good vase life; Healthy plants, good medium size for bouquets; Less prone to melt down and weak neck than larger zinnias, gives great texture in bouquets when used with large zinnias or lisianthus; Pretty multi-layered flowers, color very uniform; People and hummingbirds like zinnias; They are cute and mix well with the other Oklahomas, disease free; Easy to grow, bloomed for most of the growing season; Fantastic performers! Tall plants produced long stems, blooms were typically 2 inches or more in diameter and were in a variety of different forms – from standard zinnia to ball dahlia – many with interesting curled petals and/or tones of color, a really intriguing seed mix! Our customers loved these delightful blooms, kids liked them also, we often combined the Oklahoma Pink and Scarlet for a surprisingly cheerful mix!; Flowers held a long time on the plants; Vigorous growth, good germination, easy to transplant and establish in the field.


Found flowers to be too small for our uses (4); Not much different than other OK’s I grown; Lots of different shapes and sizes in the flowers, only ended up with 6 plants out of initial planting of 48; Some washed out pink blooms were produced; All had to be sprayed for fungus, due to our very rainy summer, flowers are too small; Smaller than rest of Oklahoma series; Uneveness of color between plants: some were coral, some lighter or darker pink; Hard to get a really long stem when cutting; many flowers were left unharvested and the yield is not reflective of actual production; Mildew; Standard zinnia problems, weak neck, barely acceptable vase life, we would not choose to grow these zinnias again; Color is so candy pink, a little boring; Sensitive to our high EC water; Only about half flowers fully double, plants tall but usable stems shorter than the ‘Giants’; We had the usual problem of short holding for all zinnias, problems with Japanese beetles and leaf spot; WAAAAAAY too short, and the flower heads are useless to us for the way we sell zinnias- by the stem….couldn’t ask as much for them, therefore I won’t grow them again; None.

I had the following trouble with all of the zinnias, but will write these comments only once: We had more snow here in Maine than people had remembered in 30 or more years, 22 plowable storms which meant the ground never froze, as a result, grub and cutworm populations were extremely high, this fact may explain why I had terrible seed germination as well as high seedling loss in all of the zinnia and sunflowers that were direct seeded – of the ones that survived, we had 16 days of almost continuous rain in July/August along with 3 hail storms, so, the mere fact that I had any flowers at all shows how tough zinnias are in general; Susceptible to Japanese Beetles; Harvested between 7/10-8/8 (transplanted to field April 22), harvested 7/10-8/8 (transplanted to field May 22); Entire zinnia crop was planted late while I was out of town – this year, I pinched in August and cut back severely in late August which did increase stem length, I could have sold all of the large flowered ones if I’d been able to keep the mildew preventative spray; Flower head = 4 cm; Great little zinnias! I liked having the separate pink in addition to my regular Oklahoma mix, it was especially useful for special events when a color theme was used, in the past I only offered a mix of colors.


Remove about 1/3 of leaves (lower ones); Surface sterilize stems in a 10% bleach solution, we don’t use floral preservative with zinnias, we avoid keeping them in the cooler; We only used plain water; Oklahoma Pink benefits from the addition of a floral preservative.
