Rare fruit/vegetable question.

I have one fruit/vegetable to get/find to complete collection. It's listed as rare, so I'm looking for a complete list of rare fruit/vegetables so I can at least figure out the name of the one I'm missing. (Don't know if this helps but the greyed out picture looks like a vine with swirly vines shooting out of it. If anyone could help I would appreciate it, it's driving me crazy that I can't fine the last one I need to complete the collection. Thank you.
