Fruits.  Paula and Yvonne

I grow on vines

I grow on bushes

Pale green

Dark blue

Colorful

Dry me up I become a raisin

Homebrewed jam

I am sweet

I become wine

Iconic, like Abraham

Classy

Crush me and I change shape

On the contrary,

We’re NOT vegetables

I am a grape

I am a blueberry

We’re fruits
