{"type":"firestarter.listing","listing":{"id":"lst_hx9nvJHi","product_name":"Black Button Centaurea","category":"Flowers","description":"This isn't your classic light blue cornflower; this is its dramatic, moody cousin. 'Black Button' is a stunning variation of the beloved bachelor's button, offering an abundance of double and semi-double blooms in a rich, super-dark maroon that reads as almost black in the garden. The upright plants grow tall, up to 38 inches (and may appreciate a little staking), providing a long season of striking color. They are a classic for a reason: they make a fantastic fresh-cut flower and are also wonderful for drying, holding their deep color beautifully.\n\nThe flowers are more than just a pretty face; they're also a delight in the kitchen. The edible petals have a mild floral flavor and make a truly sophisticated garnish for salads, desserts, or cheese platters. As a cool-season lover, this plant is easy to grow and will often self-sow, returning for another show the following year. If you can bear to leave the seed heads, you'll also provide a welcome treat for garden birds.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/files/312.png?v=1764359152","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/313.png?v=1764359152"],"price":5.39,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:34.386Z"},"share_url":"https://firestarter.network/l/lst_hx9nvJHi","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
