About Red Treviso
Red Treviso is an annual selection of leaf chicory, with an upright/erect habit and an expected height or spread of 13–18 in. It is best suited to salad leaves, cooking greens, forcing or blanching where appropriate, and seed saving. Notable traits include red coloring; harvest leaves or heads at the intended market stage; forcing types need separate handling; pleasant bitterness balanced by crisp texture.
Treat Red Treviso as a named seed line with its own observations, not as a generic stand-in for the entire leaf chicory crop.
History and provenance
Leafy greens have been selected for rosette form, head type, color, texture, bitterness, season, and bolt resistance. Mixtures and market classes should not be given a single invented pedigree, and forcing chicory, endive, lettuce, and spinach remain botanically distinct crops. Endive Seeds - Red Treviso 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. Radicchio types color and head best under cool conditions and should not be described as ordinary green endive.

Harvest and use
Approximately 60-69 Days, from direct sowing or transplanting to the listed leaf or head stage. Weather, soil temperature, and planting method can shift the actual harvest date. Harvest: Harvest leaves or heads at the intended market stage; forcing types need separate handling. Uses: Salad leaves, cooking greens, forcing or blanching where appropriate, and seed saving. Flavor: pleasant bitterness balanced by crisp texture. Seed saving: Open-pollinated herb or leafy crop. Best uses include salad leaves, cooking greens, forcing or blanching where appropriate, and seed saving. Flavor and eating quality: pleasant bitterness balanced by crisp texture.
Saving seed
Select several healthy, true-to-type Red Treviso plants that match the expected upright/erect habit and overall plant form. Avoid saving seed only from the earliest or largest individual unless that is your deliberate selection goal. Pollination system: Open-pollinated herb or leafy crop. Compatible plants of the same species may cross to varying degrees through insects or wind. Separate compatible varieties that may flower together, or use cages, barriers, hand pollination, or another documented control appropriate to the crop. Allow selected plants to pass the eating stage and reach full botanical seed maturity. Harvest only when seed heads, pods, or fruits have matured enough for sound seed development. 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: Aphids, slugs, leaf miners, caterpillars, damping-off, bottom rot, and premature bolting under stress. Management: Use clean beds, even moisture, spacing for airflow, crop rotation, and harvest before heat or crowding lowers quality. 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.
