Zinnia 'Cresto Red'

Cresto Red (Zinnia elegans)

Cresto Red Zinnia is a sunlit spectacle in the garden, unfurling lush layers of crimson petals in a dazzling scabiosa form. Most blooms are fully double, while a scattering of semi-double and single flowers add a touch of natural variety. Each stem holds its bloom proudly, perfect for snipping and bringing indoors, where its rich colour glows in a vase. This cut-and-come-again wonder offers armfuls of flowers throughout summer and into the cooling days of autumn, each one calling to butterflies and hummingbirds with its vibrant charm.

With its heat-loving nature, drought tolerance, and resistance to deer and rabbits, Cresto Red thrives in sunny beds and cutting gardens alike. The deep, romantic red pairs beautifully with soft peach cosmos, golden rudbeckia, or the airy whites of baby’s breath. Whether woven into bouquets or standing tall in a border, this zinnia brings a bold, almost painterly drama to every view.

HOW TO GROW:
Indoors (recommended): Sow seeds into seedling containers 4–6 weeks before the last frost. Cover the seeds, as they require darkness to germinate. A heat mat will help maintain an optimal temperature of 21–24°C. Lower temperatures will result in slower germination. Do not allow plants to become root-bound. Harden off seedlings for 7–10 days before transplanting them outdoors after all danger of frost has passed.

Direct Seed (alternative): Sow seeds directly outdoors after the last frost. For a prolonged harvest, succession-sow every two weeks until midsummer.

Pinching: To encourage strong branching and a more abundant bloom, pinch the initial bud or bloom from the plant when it is young. Continue to deadhead spent flowers throughout the season.

Soil Preference and Watering: Zinnias thrive in full sun and prefer well-drained, fertile soil. Keep the soil consistently moist, but avoid overwatering, which can lead to mildew.

Fertilizing: Zinnias are heavy feeders. Amending the soil with compost before planting is recommended. You can also use a balanced, all-purpose fertilizer every 4–6 weeks to encourage continuous blooming.

Harvesting: For bouquets, harvest stems when the flowers are fully open but still firm. To check if a zinnia is ready to be harvested, gently shake the stem; if the neck is wobbly, it's not ready. Harvest in the early morning or late evening and immediately place in a vase of water.
