The 2x Pot \u0026amp; Compost option is two plants supplied with pots and compost.\u003c\/p\u003e\n","brand":"Lincolnshire Pond Plants","offers":[{"title":"1 \/ 7cm Bareroot","offer_id":54368597868877,"sku":"MP088-plug","price":2.6,"currency_code":"GBP","in_stock":false},{"title":"1 \/ 9cm Bareroot","offer_id":54368597901645,"sku":"MP088-9cm","price":6.8,"currency_code":"GBP","in_stock":false},{"title":"1 \/ 9cm Potted","offer_id":54324723056973,"sku":"MP088-9cmpot","price":8.8,"currency_code":"GBP","in_stock":false},{"title":"1 \/ 1Ltr Bareroot","offer_id":54368597934413,"sku":"MP088-1ltr","price":10.72,"currency_code":"GBP","in_stock":false},{"title":"1 \/ 1Ltr Potted","offer_id":54324723122509,"sku":"MP088-1ltrpot","price":12.67,"currency_code":"GBP","in_stock":false},{"title":"1 \/ 3Ltr Bareroot","offer_id":54368597967181,"sku":"MP088-3ltr","price":19.5,"currency_code":"GBP","in_stock":true},{"title":"1 \/ 3Ltr Potted","offer_id":54324723188045,"sku":"MP088-3ltrpot","price":23.4,"currency_code":"GBP","in_stock":true},{"title":"1 \/ 2x Pot \u0026 Compost","offer_id":54368597999949,"sku":"MP088-2xpot-2xcompost","price":24.0,"currency_code":"GBP","in_stock":false},{"title":"3 \/ 7cm Bareroot","offer_id":54368598032717,"sku":"MP088-Plug-3x","price":7.41,"currency_code":"GBP","in_stock":false},{"title":"3 \/ 9cm Bareroot","offer_id":54368598065485,"sku":"MP088-9cm-3x","price":19.38,"currency_code":"GBP","in_stock":false},{"title":"3 \/ 1Ltr Bareroot","offer_id":54368598098253,"sku":"MP088-1Ltr-3x","price":30.55,"currency_code":"GBP","in_stock":false},{"title":"3 \/ 3Ltr Bareroot","offer_id":54368598131021,"sku":"MP088-3Ltr-3x","price":55.58,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/6961\/6973\/files\/Persicaria-amphibia-Polygonum.jpg?v=1788253273","url":"https:\/\/thefoalyard.co.uk\/products\/lincolnshire-pond-plants-persicaria-amphibia-amphibious-bistort-native-floating-leaved-pond-plant","provider":"The Foalyard","version":"1.0","type":"link"}
