Botanical Name: Cynara scolymu.s
Height: 3' - 4'.
Spacing: Space seed when planting 3" - 4", in rows 36" - 48" apart. Thin to 24" - 36" apart.
Depth: 1/4" - 1/2" deep.
Sun/Shade: Full sun.
Yield: Nearly 3 times the yield of older varieties - Green Globe had 6-10 buds per plant. Yields of 3 1/2" - 4" chokes (preferred by the fresh market) vary from 400 - 500 cartons per acre. Cartons average 23 lbs each with 24 or 36 chokes per carton.
Fruit: Primarily green globes can have some purple tinting.
Days To Maturity: 85 days (105 - 160 direct sown).
Soil Requirements: Well drained, humus enriched soil.
Seed Count: Approximately 25 seeds per packet.
Size: 3 1/2" to 4" diameter round green chokes with purple highlights.
Comments: Select a planting site that is in full sun and has well-drained soil and lots of organic matter. Most ground that is heavily amended with compost and other humus will have the right acidity level. Set transplants, offsets and juvenile plants out after the soil temperature is 50 degrees F. or higher, and the danger of frost is past. Make sure the soil is loosened to at least 12" in depth, so tap roots can be positioned straight down. Space plants widely, since they will eventually grow to 5 feet in height and more than 40" in width. If the climate is hot, mulch plants thickly to keep the soil cool. If soil temps exceed 85 degrees F. plants will go into sSmmer dormancy and they will not produce buds (from Mother Earth News).
