Globe artichoke is a handsome, mostly hardy perennial, valued for its tight edible flower buds and grey, architectural foliage. It makes a dramatic feature in a sunny vegetable plot or mixed border, and can remain productive for several seasons in a sheltered garden.

When and how to sow

Set out rooted offsets or sturdy young plants in April or May, once the ground has warmed and severe frost is unlikely. Choose a sunny, sheltered position with rich, free-draining soil improved with garden compost. Allow 90 cm between plants, as mature clumps are large. 'Green Globe' and 'Violetta di Chioggia' are reliable choices. In northern gardens, a warm wall can improve establishment.

Care

Water during dry spells, especially while buds are forming, and mulch with compost to conserve moisture. Remove weeds while plants are young. Crop lightly in the first year, then cut back tired stems after harvest. In colder districts, protect crowns over winter with a dry mulch or fleece. Divide or replace plants every three years.

Common problems

Slugs and snails can damage new growth, so check beneath foliage and keep surrounding soil tidy. Aphids may gather in developing buds and can be washed away with water. Grey mould is more likely in wet, crowded conditions; provide generous spacing, remove damaged leaves and avoid leaving dead material around crowns.

Harvest

Cut the main bud first, while it is plump, green and tightly closed, using clean secateurs and leaving a short stem. Smaller side buds follow afterwards. Do not wait for the scales to spread, as buds then become coarse. Unpicked buds open into striking purple flowers for pollinators.
