About Imperator 58
Imperator 58 is a biennial selection of carrot, with a rosette habit and an expected height or spread of 13–18 in. It is best suited to fresh roots, storage, cooking, color diversity, and seed saving. Notable traits include harvest when shoulders reach the expected cultivar width and roots have developed full color; sweet and aromatic with texture shaped by soil and harvest age.
Imperator 58 is kept under its own packet name and should not be treated as interchangeable with every other carrot selection.
History and provenance
Cultivated carrots were shaped from Eurasian wild carrot populations, with early selection emphasizing aromatic roots and later regional selection producing familiar orange, yellow, white, red, and purple garden forms. Modern market classes such as Nantes, Danvers, Chantenay, Imperator, and round forcing types describe root form more reliably than an unsupported pedigree story. Carrot Seeds - Imperator 58 belongs to a plant lineage long associated with Mediterranean and Old World garden agriculture. It was selected over generations for kitchen, market, ornamental, or herbal value and remains useful in modern home gardens. Imperator types are long and slender and need deeply prepared soil for straight roots.

Starting Imperator 58 from seed
Sow 1/4 in deep and keep the seed zone evenly moist. Expect emergence in 10-21 Days when the seed-zone temperature is near 55–70 °F. Germination preparation: Direct sow into a prepared, weed-free seedbed; avoid disturbing developing roots or dense stands. Light requirement: Cover evenly to 1/4 in. Soaking: Optional short soak; do not leave seed waterlogged. Stratification: None required. Scarification: None required.
Planting and care
Plant during spring and provide full sun. Space plants 2 in apart with 12 in between rows. Use sandy loam with a pH near 6.0–6.5, and follow a moderate watering plan. Support requirement: No-Support. Frost response: Semi-Hardy. Good container fit with drainage, even moisture, and the listed spacing
Harvest and use
Approximately 70-79 Days, from direct sowing to market-size roots. Weather, soil temperature, and planting method can shift the actual harvest date. Harvest: Harvest when shoulders reach the expected cultivar width and roots have developed full color. Uses: Fresh roots, storage, cooking, color diversity, and seed saving. Flavor: sweet and aromatic with texture shaped by soil and harvest age. Seed saving: Insect-pollinated umbel crop. Best uses include fresh roots, storage, cooking, color diversity, and seed saving. Flavor and eating quality: sweet and aromatic with texture shaped by soil and harvest age.
Saving seed
Select several healthy, true-to-type Imperator 58 plants that match the expected rosette habit and overall plant form. Avoid saving seed only from the earliest or largest individual unless that is your deliberate selection goal. Pollination system: Insect-pollinated umbel crop. Compatible plants of the same species can cross through insect activity; wild relatives matter for carrot and parsnip. Separate compatible varieties that may flower together, or use cages, barriers, hand pollination, or another documented control appropriate to the crop. Imperator 58 is a biennial. Seed production may require overwintering, vernalization, or more than one growing season, depending on climate and crop biology. Clean the seed carefully, dry it thoroughly away from direct heat, label the lot with variety and year, and store it cool, dark, and dry. Test germination before an important planting or distribution season.
Common problems
Common concerns: Carrot rust fly or root maggot where present, aphids, caterpillars, leaf spots, damping-off, and uneven emergence from crusted soil. Management: Use clean seedbeds, rotation, careful watering, prompt thinning, airflow, and locally appropriate exclusion methods. Diagnosis note: Similar symptoms can have different causes. Compare plants of the same age, record weather and irrigation, and use local Extension or diagnostic support before applying a control.
