Globe artichoke 'Imperial Star'

Keep in mind when planting that Imperial Star is thought of as half hardy, so it will need cloching or fleece protection when the temperature dips. Imperial Star needs a loamy and sandy soil with a ph of 5.6 to 6.6 (weakly acidic soil).

These seeds should be stratified (kept at a temperature between 33 and 49 degrees Fahrenheit) for at least 500 hours. Start indoors eight weeks before last frost date.

Try to ensure a gap of at least 1.95 feet (60.0 cm) when sowing to prevent overcrowding your seedlings. Soil temperature should be kept higher than 18°C / 64°F to ensure good germination.

By our calculations, you should look at sowing Imperial Star about 48 days before your last frost date.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Imperial Star is a half hardy plant.

Six to eight artichokes per plant.
