Giant Lilac Heirloom Zinnia Seeds

Giant Lilac Heirloom Zinnias are one of our farm favorites. They produce beautiful oversized blooms in soft lilac tones and flower generously throughout the season, bringing gentle color to cutting gardens and summer bouquets.

The blooms are also popular with bees, butterflies, and other garden pollinators.

What to Expect

• Large blooms in soft lilac tones

• Generous flower and seed production

• Useful stems for cutting and bouquets

• Strong appeal for pollinator gardens

Good to know: Zinnias are warm-season, frost-sensitive annuals that respond well to regular cutting. Pinching young plants can encourage branching and more usable stems.

•
Sun: Full sun, ideally 6–8 hours daily

•
Sowing: Plant about ¼ inch deep after the danger of frost has passed

•
Spacing: 9–12 inches for good airflow and larger plants

•
Care: Consistent water, fertile soil, and regular feeding help support large, full blooms

•
Bloom season: Summer through the first frost

Cut flowers often or remove spent blooms to encourage continued production.

Heirloom note: Bloom color, size, and fullness may vary naturally and can be influenced by growing conditions.
Production note: Zinnias are cut-and-come-again flowers. Pinching when young and harvesting regularly can encourage branching and continued stem production.
