Zinnia 'Key Lime Pie'

Key Lime Pie (Zinnia elegans)

Key Lime Pie Zinnia Mix is a lively and unexpected delight in the garden, blending the soft chartreuse tones of Green Envy with the crisp, pure white of Polar Bear. Fully double, dahlia-like blooms measuring 4–6 inches across crown long, sturdy stems, perfect for cutting into bouquets that glow with freshness and elegance. Each flower brings a playful yet sophisticated touch to garden beds, borders, or floral arrangements, while its unique combination of greens and whites creates a luminous, refreshing palette unlike any other.

Vigorous plants reach 3–4 feet tall, holding strong through summer heat and rain with low susceptibility to powdery mildew. Their cut-and-come-again habit provides multiple harvests over the season, offering continuous blooms with excellent vase life.

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.
