{"product_id":"agastache-black-adder","title":"Agastache 'Black Adder'","description":"\u003cp\u003eAgastache 'Black Adder' is a superb plant.  We think that this is one of the best plants recently introduced. It is a clump forming deciduous perennial with smokey-lilac flowers opening from dark purple buds over a long period from July to October. Approx. 1m tall or taller so good at the back of a border or planted to make a statement. Fantastic at attracting bees and butterflies. Best in sun in a very well-drained, soil. Can be cut back to encourage a second flush of flowers.\u003cbr\u003e \u003cbr\u003et mixes well with other plants of similar colours or with contrasts.  Nepetas with their lilac-blue flowers and silvery foliage, Echinacea in pink or white forms, Coreopsis or Anthemis. \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e2 Litre Pot\u003c\/p\u003e","brand":"Caths Garden Plants","offers":[{"title":"Large","offer_id":32279856152610,"sku":"agastache-black-adder-barerooted","price":9.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0291\/1957\/8146\/products\/E3B9D177-84AF-487B-8567-0F76BF51A418.jpg?v=1599680443","url":"https:\/\/www.cathsgardenplants.co.uk\/products\/agastache-black-adder","provider":"Caths Garden Plants","version":"1.0","type":"link"}
