Who Am I? (squash version)

I was planted in spring.
I grew all summer long.
My vines have grown thick,
Hearty and strong.

I am orange like a basketball,
But I do not bounce.
I have lots of seeds inside -
Too many to count.

My stem is dark green.
My flesh is shiny and bright.
I've also been known
To glow at night.

I taste really good
Baked in a pie.
Can you tell me
Who am I?
