Triple-tested seed qualityRegular quality and germination checks support every packet.

We regularly test seed quality and germination as lots move through storage and packing. We stand behind the seed we send and want customers to contact us when a packet does not perform as reasonably expected.

1-year seed warrantyCoverage begins on the date of purchase.

When properly stored, planted, and cared for, we guarantee reasonable germination and true-to-type growth for one year from the date of purchase. Conditions outside our control—including extreme weather, pests, unsuitable storage, and gardener error—are excluded. Contact us when something is not right so we can review the situation and work toward a replacement, refund, or another fair resolution.

California Giant Mixed Zinnia seeds produce mixed bloom on 37–48 in upright/erect plants. Annual growth and Summer/Fall bloom make it useful for cut flowers, warm-season color, pollinator gardens, borders, and seed saving. California Giant Mixed produces large, fully double flowers in red, orange, pink, purple, yellow, white, and intermediate tones. Strong upright stems make the tall plants useful in cutting rows, while regular harvest or deadheading encourages continued summer bloom.

About California Giant Mixed

California Giant Mixed is an annual zinnia with mixed color, 37–48 in mature height or spread, and an upright/erect habit. Harvest form or size: Flower or head form characteristic of California Giant Mixed; mature plant 37–48 in. Botanically it is Zinnia elegans. Maturity or first bloom: 70-79 Days; germination: 5-10 Days at 70–85 °F. Best for cut flowers, warm-season color, pollinator gardens, borders, and seed saving. Grown for ornamental or habitat use rather than as a food crop.

History and provenance

Zinnias are native to Mexico and nearby parts of the Americas. Garden breeding transformed relatively simple wild flower forms into broad color ranges, dwarf bedding lines, tall cutting strains, cactus-flowered forms, and striped or bicolored selections. The named cultivar is treated as the maintained seed strain offered under this name; a breeder or release date is not added without a reliable record. A complete public breeder or release record for the named California Giant Mixed strain has not been located. The cultivar name is retained, but no person, community, date, or place of origin is assigned without reliable documentation.

Starting California Giant Mixed from seed

How to grow California Giant Mixed Zinnia

Botanical identity: Zinnia elegans. Life cycle: Annual.

Sow 1/4 in and use a seed-zone temperature near 70–85 °F. Expected emergence: 5-10 Days. Use clean seed-starting conditions, the listed depth and temperature, and steady moisture without saturation.

Plant during Late Spring. Space plants 10 in apart with 18 in between rows or planting bands.

Provide Full sun, moderate water, and loamy near pH 6.0–6.5. Support: No-Support.

Garden performance and care

For a longer display of California Giant Mixed, remove spent blooms unless seed is being saved. Give the plant its listed spacing, cut flowers with clean tools, and leave selected heads to mature fully for seed. Expected emergence is 5-10 Days; the listed maturity or bloom timing is 70-79 Days.

Harvest, bloom, and uses

California Giant Mixed is suited to cut flowers, warm-season color, pollinator gardens, borders, and seed saving. Its mixed flowers and 37–48 in stature help determine whether it belongs in a border, cutting row, container, meadow edge, or restoration-style planting. Grown for ornamental or habitat use rather than as a food crop.

Saving seed

California Giant Mixed contains more than one genetic line or species. Seed collected from the planting will not reproduce the original packet proportions. If saving seed, identify species separately, prevent unwanted crossing where possible, harvest only fully mature seed, dry thoroughly, and label each lot by species, year, and source.

Common problems

Common concerns: damping-off from saturated media; poor emergence from wrong temperature or depth; leggy seedlings from weak light; crowding and weak airflow; lodging in wind or rain; feeding damage from slugs, caterpillars, beetles, or mammals; foliar disease under prolonged leaf wetness; powdery mildew and bacterial leaf spotting under crowded, wet foliage. Management: use clean media, the sowing depth and temperature, strong light, appropriate thinning, and morning irrigation at soil level. Match support to plant height before wind becomes a problem. Inspect regularly and use the least disruptive control appropriate to the pest, plant, and pollinator setting. Remove diseased debris and rotate annual flower beds where recurring disease is severe.
