Lemon Queen Sunflower seeds produce yellow bloom on 61–72 in upright/erect plants. Annual growth and Summer/Fall bloom make it useful for sunny borders, cut flowers, pollinator use, seed heads, and seed saving. About Lemon Queen Lemon Queen is an annual sunflower with yellow color, 61–72 in mature height or spread, and an upright/erect habit. Harvest form or size: Flower or head form characteristic of Lemon Queen; mature plant 61–72 in. Botanically it is Helianthus annuus. Maturity or first bloom: 70-79 Days; germination: 7-14 Days at 65–80 °F. Best for sunny borders, cut flowers, pollinator use, seed heads, and seed saving. Ornamental bloom and mature seed use depend on the named strain and harvest stage. History and provenance Sunflower, Helianthus annuus, originated in North America and was cultivated by Native peoples for food, oil, dye, and other uses before its spread around the world. Modern named garden strains emphasize differences in plant height, branching, ray color, head form, seed size, and days to bloom. Public records do not document a single breeder for every catalog name, so the named strain is retained without adding an unsupported release story. A complete public breeder or release record for the named Lemon Queen strain has not been located. The cultivar name is retained, but no person, community, date, or place of origin is assigned without reliable documentation. Growing facts Scientific name Helianthus annuus Life cycle Annual Maturity / first bloom 70-79 Days Germination 7-14 Days at 65–80 °F Seed depth 1 in Plant height / spread 61–72 in Growth habit Upright/Erect Spacing 12 in between plants; 30 in between rows Sunlight Full sun Soil Loamy; pH 6.0–6.5 Water Moderate Support No-Support Starting Lemon Queen from seed How to grow Lemon Queen Sunflower Botanical identity: Helianthus annuus. Life cycle: Annual. Sow 1 in and use a seed-zone temperature near 65–80 °F. Expected emergence: 7-14 Days. Use clean seed-starting conditions, the listed depth and temperature, and steady moisture without saturation. Plant during Late Spring. Space plants 12 in apart with 30 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 Lemon Queen, 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 7-14 Days; the listed maturity or bloom timing is 70-79 Days. Harvest, bloom, and uses Lemon Queen is suited to sunny borders, cut flowers, pollinator use, seed heads, and seed saving. Its yellow flowers and 61–72 in stature help determine whether it belongs in a border, cutting row, container, meadow edge, or restoration-style planting. Ornamental bloom and mature seed use depend on the named strain and harvest stage. Saving seed Save seed from several healthy, true-to-type Lemon Queen plants identified before harvest. Confirm the pollination system of Helianthus annuus, separate compatible varieties that flower together, and remove clear off-types before they shed pollen or seed. Allow fruit, pods, ears, or seed heads to reach full biological maturity, then clean and dry the seed completely. Label the lot with variety, source, year, isolation method, number of seed plants, and any selection notes; store it cool, dark, and dry and test germination before an important planting. 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; bird or squirrel feeding on maturing heads; stem lodging on giant plants. 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 Lemon Queen 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 7-14 Days near 65–80 °F; actual emergence changes with moisture, seed condition, and soil temperature. How large does it grow? About 61–72 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: Sunny borders, cut flowers, pollinator use, seed heads, and seed saving. Ornamental bloom and mature seed use depend on the named strain and harvest stage. 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. Minimum Seed Count:50 seeds
