When can I harvest globe artichokes?

June to August in most UK gardens — but only from year 2 onwards. Year 1 plants should have any flower buds removed early to let the plant establish; cropping starts in year 2. Cut buds when fully formed but tightly closed — the scales should still be pressed together, the bud feels firm. Use secateurs, leaving 5–10 cm of stem. Once the scales start to spread (the bud is becoming a flower), it's too late — the choke inside has developed.

Will globe artichokes survive a UK winter?

Hardy in most UK gardens with proper protection (RHS H4) — survives down to about -10°C with a thick crown mulch. Main UK risk is cold wet winters on heavy soils: the crown rots. Protection regime: cut spent stems to 30 cm in November, pile 15–20 cm of dry mulch (bracken, straw, leaves) over the crown, remove mulch in spring. In very cold gardens (Highland Scotland): grow in a large pot that moves to a cold greenhouse for winter.

How many globe artichokes will one plant produce?

4–6 buds per year at peak (years 3–5). Year 1: zero (let it establish). Year 2: 1–3 buds. Years 3–5: full cropping (4–6 buds). Years 5+: declining (3–4 buds). For a household: plant 2–3 globe artichokes spaced 1 m apart for a regular weekly harvest from June through August during peak years. Each bud is a single artichoke serving.

What's the difference between globe artichoke and Jerusalem artichoke?

Completely different plants — and the names mislead. Globe artichoke (Cynara cardunculus var. scolymus, this plant): a thistle relative grown for the unopened flower buds. Jerusalem artichoke (Helianthus tuberosus — see separate jerusalem-artichoke slug): a sunflower relative grown for the underground tubers. The Jerusalem name is a corruption of the Italian girasole (sunflower); they have no botanical or culinary connection to globe artichokes despite sharing the word.

Why are my globe artichoke buds small or spiny?

Three causes. (1) Seed-grown plant: seedling artichokes are variable — many produce small spiny buds with poor flavour. Replace with named-variety offsets (Green Globe, Violetto di Chioggia). (2) Too young or too old: year-2 plants produce smaller buds than peak (years 3–5); year-5+ plants decline. Plant fresh offsets every few years. (3) Drought stress: artichokes shut down in dry weather, producing small tough buds. Water deeply weekly in dry spells.

Can I grow globe artichokes in a pot?

Yes — and in cold gardens it's often the only way. Use a 50 cm deep pot of peat-free compost mixed with garden compost. Position in full sun. Advantage: the pot can move to a cold greenhouse or sheltered porch for winter protection. Disadvantages: pot plants are smaller and crop less (2–4 buds vs 4–6); they need more regular feeding (monthly liquid feed) and watering. Repot every 2–3 years; refresh top compost annually. Lift offsets from pot plants the same way as ground plants.

Alcachofa

Cynara scolymus

Plante los brotes de alcachofa en primavera, a pleno sol y en un suelo profundo y bien drenado; se trata de unas hermosas plantas perennes (de 1,5 m de altura) que se cultivan por sus capullos inmaduros, que se consumen antes de que se abran. Las alcachofas son moderadamente resistentes (RHS H4) y sobreviven a la mayoría de los inviernos del Reino Unido con un mantillo grueso en la corona; en jardines fríos o húmedos pueden morir. Green Globe y Violetto di Chioggia son las variedades más populares en el Reino Unido. Plante los brotes (pequeños tallos enraizados que salen de la base de las plantas adultas) en lugar de semillas, ya que las plantas cultivadas a partir de semillas son variables y a menudo espinosas. Corta los capullos cuando estén completamente formados pero aún bien cerrados; una vez que se abren las escamas, ya es demasiado tarde, el capullo se ha convertido en flor. Reemplázalos cada 4-5 años plantando esquejes nuevos; las plantas establecidas se vuelven menos productivas. Su forma es lo suficientemente arquitectónica como para merecer un lugar en tu jardín, incluso si nunca las cosechas.
