These Windsor residents are trying to grow a giant pumpkin on their front lawn

Over the past few months, whenever people walk by Greg Underwood's Walkerville home, in Windsor, Ont., and see him outside, they often point to his front lawn and ask, 'what is it?' 

"I've told a few people that have passed by that it was a giant pumpkin," said Underwood. 

It's a familiar fall sight, just in an unfamiliar place. The pumpkin itself isn't as big as Underwood had hoped, but the plant has almost completely blanketed his front lawn. 

"I had no idea that it would, in fact, take over the yard," he said with a chuckle. 

Underwood had been on a business trip when he saw that a client of his had a photo of a massive pumpkin.

"I said, 'so do you grow giant pumpkins? And he said, 'sure, are you interested? ... I thought, 'gee that would be kind of neat to try and replicate that.'"

He says the expert grower from Michigan, Cecil Weston, gave him an entire giant pumpkin growing kit, which included several seeds from his past champion pumpkins that have won contests. 

Underwood took some of the seeds and started growing them in a container indoors this spring, before eventually planting them outside. 

"After I started them, I realized we didn't have a real good place to put them in our yard and I thought if they get real big, how am I going to move them? So by default I guess they ended up in the front yard." 

Underwood was already dreaming of using the pumpkins in the big Halloween display he and his wife, Paula Brook, do every year outside of their home. 

"The movie about Christmas vacation and how he had 20,000 lights around his house, that's kind of what our house looks a little bit like, lots of lights, inflatables ... banners hanging, that sort of stuff," he said. 

But he wanted to surprise Brook, so for months he kept the plant's identity a secret. A few weeks ago, Brook caught on when she saw the pumpkins that started growing. 

Though it's unlikely the pumpkin will grow that much bigger in the coming weeks, Underwood and Brook are hoping nothing happens to it so that they can display it with their other Halloween decor.
