Zinnia 'Oklahoma Ivory'

Zinnia elegans

• Assortment of warm cream, ivory colours
• 35-40mm double and semi-double flowers on tall, sturdy stems
• Long vase life - excellent supporting bloom
• Cut and come again plants

With an assortment of ivory tones ranging from buttery and pale straw to blush-touched cream and soft creamy limoncello, Oklahoma Ivory stands alone while somehow enhancing everything planted beside it. A wonderful companion to roses, other zinnias, cosmos, echinacea, dahlias, purple basil (stunning!), stock, poppies and larkspur, it brings light, movement and warmth both in the garden and in arrangements.

The double to semi-double blooms unfurl with softly twilled petals emerging from the centre, while ageing petals deepen and intensify in colour. Its shifting tones give it an almost chameleon quality in arrangements.

I remember being non-committal about allocating it space.

Oklahoma Ivory should never be an afterthought.

Thank Frank Morton for saving this exquisite little gem from fading away. Tight spacing encourages longer stems. With blooms around the size of a 50-cent piece and a wonderfully high percentage of fluffy, beautifully diverse double flowers, Oklahoma Ivory is a dream accent bloom.

Seed Raising, Growing and Harvest Information

TRANSPLANT (recommended) - Sow into flats or preferred seedling container 4 weeks before last frost. Cover seeds lightly with vermiculite to help maintain moisture. Seeds will germinate in 3–5 days when temperatures are kept at 27–29°C. After germination, grow at 20°C during the day and 16-18°C at night. Harden-off and transplant out after last frost. Do not allow plants to become root bound and avoid disturbing roots; transplant shock or other stress events may cause double-flowering varieties to produce single blooms for a period following stress.

DIRECT SEED - After last frost, and when soil has warmed to 20°C, sow seeds just covering firmly with soil. For cut flower production, thin seedlings or plant plugs at 20-25 cm in rows 30 cm apart.

HARVEST - Harvest in the cool of the day into clean water. Zinnias dislike cold storage. It is best to store them in a cooler set to a temperature above 45°F/7°C or place them in a cool barn, garage, or an air- conditioned room. After Zinnias have cooled from the heat of the field, transfer them into water with a holding solution (a biocide and a pH reducer). This, in addition to changing the water, can extend the vase life to 7 days.

NOTES - Succession-sow/plant every two weeks for prolonged yields of high-quality stems. Pinching of initial bud or bloom and subsequent deadheading is recommended to encourage strong branching and bloom production.
