John's son, Bruce, carries on the family tradition so you can grow your own! These bright orange pumpkins have strong handles, thick walls, and defined ribs that add to its characteristic Halloween look. Each plant produces 1–2, 18–22 pound pumpkins on long vines.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3113i_Pumpkin-Howden-ORG_pbyav8_5b01ce1c-af8f-43c6-b656-46615e6e5035.jpg?v=1773114593","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3113si_Pumpkin-Howden-ORG_669086b3-9262-4e0b-b091-9e539484645d.jpg?v=1773114593","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3113w_Pumpkin-Howden-ORG_n748sz_004125ec-dcb5-48cf-b9ba-ca48455fc640.jpg?v=1773114593","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/howden-pumpkin-seeds.jpg?v=1773114593"],"price":4.49,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:02.726Z"},"share_url":"https://firestarter.network/l/lst_Citnrzju","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
