Stop Sign Mix Zinnia seeds produce red bloom on 25–30 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. Stop Sign Mix produces a vibrant display of large, single flowers in multiple warm colors, with individual plants varying in tone, petal gradient, and pattern. Robust upright plants tolerate summer heat and dry periods in full sun. Repeated bloom provides lively garden color while inviting bees and butterflies.
About Stop Sign Mix
Stop Sign Mix is an annual zinnia with red color, 25–30 in mature height or spread, and an upright/erect habit. Harvest form or size: Flower or head form characteristic of Stop Sign Mix; mature plant 25–30 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 Stop Sign Mix 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 Stop Sign Mix from seed
How to grow Stop Sign Mix 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 Stop Sign Mix, 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
Stop Sign Mix is suited to cut flowers, warm-season color, pollinator gardens, borders, and seed saving. Its red flowers and 25–30 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
Stop Sign Mix 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.
Frequently asked questions
When is Stop Sign Mix ready?
70-79 Days from sowing to the primary bloom or market stage used for the listed maturity range
How long does germination take?
Expect 5-10 Days near 70–85 °F; actual emergence changes with moisture, seed condition, and soil temperature.
How large does it grow?
About 25–30 in with an upright/erect habit. Support: No-Support.
Can it grow in a container?
Possible in a large container, raised bed, or in-ground planting with room for the mature plant
How is it used?
Primary role: Cut flowers, warm-season color, pollinator gardens, borders, and seed saving. Grown for ornamental or habitat use rather than as a food crop.
Can I save seed?
Yes where the crop biology allows, but keep compatible varieties isolated, use several healthy plants, wait for full seed maturity, dry thoroughly, and label the lot.
