Calypso changes that: an RHS AGM variety bred specifically to resist bolting, giving weeks more usable leaf than an unselected plant.\u003c\/p\u003e\n\n\u003ch2\u003eCoriander Calypso – The One That Actually Works\u003c\/h2\u003e\n\n\u003cp\u003eThe name coriander is said to derive from koris, the Greek for 'bedbug', because the unripe plant smells strongly of the insect. Seeds have been found in tombs from the 21st Egyptian Dynasty (1085–945 BC). The Chinese once believed it bestowed immortality. In the Middle Ages it went into love potions. Given all that, it's a little anticlimactic that coriander's main reputation in British gardens is for bolting in June and being useless by July.\u003c\/p\u003e\n\n\u003cp\u003eCalypso was bred specifically to resist that tendency. It holds the RHS Award of Garden Merit from 2014 (H2 hardiness rating) and was selected for slow bolting, putting energy into leaves rather than rushing to flower the moment the temperature rises. In a sheltered, sunny spot with reasonable moisture, Calypso gives you several weeks of steady harvest where a standard variety would be spinning up a flower stem by week three. Harvest little and often from the top, never stripping the plant, and it keeps going. Plant it outside from mid-May onward in full sun and well-drained soil; it resents cold nights and waterlogged roots.\u003c\/p\u003e\n\n\u003ch2\u003ePlanting Companions\u003c\/h2\u003e\n\n\u003cp\u003eIn the vegetable garden, coriander grows well alongside \u003ca href=\"\/products\/dill-plants\" rel=\"noopener noreferrer\" target=\"_blank\"\u003edill\u003c\/a\u003e and basil.

Not a Factory.\u003c\/h2\u003e\n\n\u003cp\u003eOur coriander is hand-sown from named Calypso seed by our team, grown without neonicotinoids, and arrives in recycled pots.

The plant reads stress as a signal to complete its reproductive cycle. Calypso is bred to resist this and typically gives several more weeks of leaf production in comparable conditions than unselected varieties.\u003c\/p\u003e\n\n\u003ch3\u003eIs Calypso better than other coriander varieties?\u003c\/h3\u003e\n\u003cp\u003eFor leaf production in British conditions, yes. It holds the RHS AGM specifically for garden performance and bolts more slowly than standard varieties. If you want coriander seeds for cooking, any variety does the job; if you want leaves through the season, Calypso is the right choice.\u003c\/p\u003e\n\n\u003ch3\u003eCan I grow coriander in a pot?\u003c\/h3\u003e\n\u003cp\u003eNot ideal. Containers heat up and dry out quickly, exactly what triggers bolting. Coriander in a pot tends to bolt faster than in open ground. If you must use a pot, go large (30cm+), water frequently, and keep it out of direct midday sun.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I harvest coriander to get more leaves?\u003c\/h3\u003e\n\u003cp\u003eSnip individual stems from the top rather than stripping from the base. Never take more than a third of the plant at once. Harvest before any flower stems appear; once the bolt starts, leaf quality drops off quickly and the flavour changes.\u003c\/p\u003e\n\n\u003ch3\u003eDoes coriander come back every year?\u003c\/h3\u003e\n\u003cp\u003eNo. It's an annual: one season and done. It may self-seed if you let it flower, but the seedlings aren't reliable for bolt resistance: Calypso's characteristic doesn't come true from saved seed. Replace each season.\u003c\/p\u003e\n","brand":"Ashridge Nurseries","offers":[{"title":"Potted \/ P9","offer_id":56773228921158,"sku":"HERBCORSATCAL-P9","price":5.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/0351\/8022\/files\/potted-coriander-plant.webp?v=1781530851","url":"https:\/\/www.ashridgetrees.co.uk\/products\/coriander-plants","provider":"Ashridge Nurseries","version":"1.0","type":"link"}
