120 Days. This hybrid fits between our Howden Biggie and Atlantic Giant in size, and it requires more than one person to get it out of the field. It can grow from 75-150 lbs., depending on the care you give it. With a fairly uniform shape for a big pumpkin and a consistent, bright reddish-orange color, Prizewinner is an excellent contest pumpkin. Its typical pumpkin shape with shallow ribs makes it a good fit for roadside displays, too. 10 seeds/pkt. View Home Gardener Description
