Imperial Star Artichoke Product Details

Botanical Name: Cynara scolymus. PVP (Plant Variety Protected).

Days To Maturity: 85 days (105 - 160 direct sown).

Seed Count: Approximately 25 seeds per packet.

Size: 3 1/2 to 4 inches in 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. Moist soil 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 inches 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 inches 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 Summer dormancy and they will not produce buds (from Mother Earth News).
