Crystal Series Zinnia is a compact, award-winning annual that thrives in full sun across hardiness zones 3-10, reaching just 8-10 inches tall while delivering an impressive show of small, daisy-like flowers from summer through frost. The flowers bloom in vibrant orange, white, and yellow, and mature in 50-55 days from seed, making it quick enough for even impatient gardeners. This dwarf shrub combines the vigor to handle intense heat with the delicate proportions that work equally well in containers, borders, or cottage gardens.

These compact zinnias pack surprising vigor into a petite 8-10 inch frame, producing an abundance of small, cheerful daisy-like blooms in orange, white, and yellow throughout the season. The flowers are substantial enough to make a visual impact but refined enough to succeed indoors in pots, a rare combination in the zinnia world. Their heat tolerance and rapid 50-55 day bloom time mean you'll enjoy color even in the hottest part of summer, and they'll keep flowering right up until the first frost arrives.
Crystal Series Zinnias are grown primarily as ornamental flowers for summer gardens and containers. Their compact size and abundant blooms make them especially well-suited to small-space gardening, window boxes, and indoor potted displays where larger zinnias would overwhelm the setting. The cut flowers, though delicate, also work in small bouquets or as filler in floral arrangements.

Start seeds indoors 4-6 weeks before your last spring frost in warm soil (around 70-75°F). Seeds germinate quickly and don't require special treatment. Transplant seedlings into larger containers once they've developed true leaves, and keep them in a bright location.
Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before transplanting. Move them outside after all frost danger has passed and soil has warmed. Plant at the same depth they were growing in containers, spacing them 8-10 inches apart.
Direct sow seeds outdoors after the last frost date when soil has warmed. Press seeds lightly into the soil surface or cover with just a thin layer of soil, as light aids germination. Thin seedlings to 8-10 inches apart once they're established.
Pinch back young plants when they're 4-6 inches tall to encourage bushier growth and more prolific flowering. Deadhead spent flowers regularly throughout the season to keep plants blooming continuously; simply remove flowers as they fade.
