Days To Maturity
Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.

Life Cycle
Life Cycle
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).

Hybrid Status
Hybrid Status
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits.
Close
Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next. -
Open Pollinated
Perseo Radicchio Seed

SCIENTIFIC NAME:
Cichorium intybusCULTURE: For North American production, these varieties are vast improvements over older types, but are still not perfectly uniform or completely predictable. Although bred for specific seasons, it is still best to trial more than one variety, using succession plantings to determine which one suits your conditions. Radicchio is hardy and can be planted as early as the soil can be worked. It is a cool weather crop and grows best at temperatures of 60-65°F (15.5-18.3°C). Careful variety selection is important for hot weather plantings. NOTE: Radicchio grows best in cool or mild weather, i.e. fall, winter, and spring. Summer crops can be successful if nights are cool (below 60°F/16°C).THERMAL DORMANCY: Radicchio seed can enter thermal dormancy when exposed to high temperatures above 77°F (25°C). Optimum germination results at soil temperatures of 60-68°F (15.5-20°C). TRANSPLANTING: Sow in flats, 4 seeds/in., or in 3/4" plug trays, barely covering seeds with fine vermiculite, 3-4 weeks before transplanting outdoors. Shade the flats on sunny, warm days if necessary to keep the soil surface cool, below 75°F (24°C), until germination. If sowing into flats, transplant 1-2" apart into flats, pots, or cell-type containers about 2 weeks later. Harden seedlings by reducing water and temperature for 2-3 days before planting outdoors. Properly hardened transplants can survive temperatures as low as 20°F (-6°C). Transplant 8" apart in rows 18" apart. Transplant shallowly so that the base of the plant will be slightly above the soil to discourage bottom rot.DIRECT SEEDING: Seeds will germinate from 41-85°F (5-29°C), but the highest germination percentage will occur around 75°F (24°C), depending on the variety and seed lot. Sow seeds 1" apart, rows 12-18" apart. Cover seed lightly, about 1/8", and firm soil gently. Thin to 8" apart; thinnings may be transplanted. Dry soil must be watered to ensure coolness and moisture, and for uniform germination.DAYS TO MATURITY:
From date of cool weather/spring transplanting. Subtract 10-14 days for warm weather/late spring/early summer transplanting. Add about 14 days for direct seeding.AVG. DIRECT SEEDING RATE: 1M/220', 5M/1,100', 10M/2,200', 131M/acre at 3 seeds every 8" in rows 18" apart.SUCCESSION PLANTING: Sow every 3 weeks for a continuous supply of fresh radicchio. TRANSPLANTS: Avg. 500 plants/M (2 seeds per cell thinned to one seedling).SEEDS/OZ.: See individual varieties.PACKET: See individual varieties.Johnny's is committed to your success, every step of the way.
