Looks like a C. Maxima variety, especially from the photo of the plant I saw in the website.

Hi ccabal,

Thank you for answering my question. I scoured the web for young C. maxima pictures to figure out the variety. The closest one is a giant pumpkin.

I'm not used to seeing those here in Hawaii. Most folks usually grow Kabochas, so the pumpkins I'm used to seeing have all been green when young. The bright yellow fruit on my plant seemed really bizarre.

Reminds me of when my aunt first encountered a purple okinawan sweet potato. She started to peel it, saw the purple flesh, thought it was rotten, and chucked it into the garbage can. She grabbed a second one, saw the purple again, and chucked it too, into the garbage can. After the third one, she came out of the kitchen complaining that I bought a bad batch of potatoes, and proceeded to tell me how she'd never seen sweet potatoes rot and turn purple. I about fell over laughing so hard. I still start giggling when I think about that. It never occurred to me that she might not have seen a purple sweet potato.

Now the jokes on me, pumpkins are yellow from the start.

I guess I'll have to wait and see how these pumpkins turn out.

If it's not something I want to eat, I'm sure my birds and chickens will enjoy it. :-)

so how'd it turn out?
