{"type":"firestarter.listing","listing":{"id":"lst_5Yw2Mtwz","product_name":"Harris Model Parsnip","category":"Vegetables","description":"Parsnips are rewarding--primarily because they are at their best when the garden is at its meekest. From late February until mid-April, whenever the ground is unfrozen, head to your garden to unearth big, sweet parsnip roots to eat. Or, if you leave a few well-spaced parsnips in the ground to flower, they will make quite a cheery show in early spring: the tall 4-6 foot stalks have masses of yellow umbels that attract a buzzing diversity of native pollinators and beneficial garden insects. Parsnips are unbeatable roasted, and--mashed and whipped into your favorite muffin recipe--they make terrific baked goods. They do occupy garden space the whole season long, but they are delightfully free of troubles. Just plant them, weed a few times when young.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Harris-Model-Parsnip-vendor-unknown-1630675748.jpg?v=1735580409","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/40_971b42e7-1a94-47a1-b16d-ed3a227daf00.png?v=1740004164"],"price":5.39,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.743Z"},"share_url":"https://firestarter.network/l/lst_5Yw2Mtwz","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
