Zinnias (Zinnia elegans) are among the most popular annual flowers for cut arrangements due to their vibrant colors, long vase life, and prolific blooming habit. Native to Mexico, these heat-loving plants thrive in full sun and produce sturdy stems, making them ideal for bouquets. When selecting zinnia varieties for cutting, consider factors like stem length, bloom size, and color diversity.
Below are some of the best zinnia varieties specifically bred or favored for cut flower production:
This series is a favorite among florists and gardeners alike. Known for its large, dahlia-like blooms (3–4 inches in diameter) and strong, tall stems (up to 36 inches), 'Benary's Giant' offers a wide range of colors, including deep red, bright pink, and pure white. The flowers are long-lasting in vases and resist fading.
A unique choice for arrangements, the 'Queen Lime' zinnias feature muted, lime-green to blush-pink blooms. Their unusual color palette adds elegance to bouquets. Stems grow up to 30 inches tall, and the double-flowered heads provide texture and visual interest.
For smaller but abundant blooms, the 'Oklahoma' series is exceptional. These zinnias produce dense, pom-pom-like flowers on 24–30 inch stems. Their compact size makes them perfect for mixed arrangements, and they come in shades like salmon, white, and crimson.
A standout in the cut flower world, 'Uproar Rose' boasts vibrant rose-pink blooms with a slight gradient effect. The stems are robust and reach up to 40 inches, making them excellent for tall centerpieces. This variety is also disease-resistant, ensuring consistent quality.
To maximize the quality and quantity of zinnias for cutting, follow these cultivation practices:
Sow zinnia seeds directly in well-drained soil after the last frost. Space plants 9–12 inches apart to promote airflow and reduce disease risk. Crowding can lead to shorter stems and smaller blooms.
Pinch back young plants when they reach 8–12 inches tall to encourage branching. This results in more stems and flowers per plant, increasing your harvest for arrangements.
Cut zinnias early in the morning when blooms are just beginning to open. Use sharp shears and place stems immediately in water. Remove lower leaves to prevent rot and change the water every 2–3 days to prolong vase life.
Zinnias are generally low-maintenance but can face challenges like powdery mildew or aphids. Choose resistant varieties (e.g., 'Benary's Giant') and avoid overhead watering to minimize fungal issues. Insecticidal soap or neem oil can control pests without harming pollinators.
Zinnias offer unparalleled color options, from bold primaries to pastels. Mix varieties like 'Purple Prince' (deep violet) with 'Polar Bear' (creamy white) for contrast. Their versatility suits rustic, modern, or romantic arrangements, and they pair well with foliage like eucalyptus or basil.
