Standing nearly four feet tall, Benary's Giant Blend delivers the bold presence that makes zinnias legendary in cutting gardens and borders alike. The color blend aspect means you're planting mystery and variety in a single packet; each plant expresses its own personality as it unfolds. These are zinnias that don't rush, thriving only when soil and air warm completely, so waiting for true warm weather rather than planting early is the key to robust, floriferous plants.
Benary's Giant Blend is grown primarily for cut flowers, where its height, strong stems, and extended bloom window make it invaluable for arrangements from midsummer through frost. The color blend also serves ornamental borders and cottage gardens, where the mixed palette creates layered visual interest without requiring careful color coordination.

Start seeds indoors 4 to 6 weeks before your average last frost date. Maintain soil temperature between 70 and 80 degrees Fahrenheit for reliable germination. Transplant seedlings outdoors only after the last frost date has passed and soil has warmed; zinnias do not benefit from early planting and will languish in cool conditions.
Transplant outdoors after your average last frost date once soil is genuinely warm. Harden off seedlings by gradually exposing them to outdoor conditions. Space plants 10 to 12 inches apart to allow for air circulation and their full mature height of 36 to 48 inches.
Direct sowing is recommended. Sow seeds outdoors 1 to 2 weeks after your average last frost date, once soil has warmed sufficiently. Do not rush; cool soil will rot seed rather than sprout it.
