The original improved artichoke, Green Globe flowers in early summer. The flower buds are deep green with a light purple tinge. A good harvest of 3–4 heads can be expected throughout the summer. They are 3–5 inches in diameter and have thick, flavorful hearts. They will need a very fertile soil in a sunny, sheltered position. To grow from seed, sow seeds in module trays indoors in March – plant them on in to larger 10cm pots and plant out in June after hardening off. Space them at least 1 meter apart. Cover the plants with fleece if there is a risk of frost. Offsets are planted about 5cm deep. Trim the leaves to 13cm after planting. Keep plants weed free and water well. In the first year remove the flowerhead as soon as it appears – this will give you a better crop the next year. To prepare plants for the winter, remove any dead stems and dying foliage. Harvest the largest, top globe first when it turns fat and soft and just before the scales start to open out. Cut a short length of stalk with it. Then harvest the other heads as they mature. You will get approx a dozen of them between June and August. Globe Artichokes will produce globes every year for 3-4 years and then they start to produce progressively less. At this stage, it’s worth propagating new plants by cutting offsets from old ones. So their lifespan is about 5 years in total.
