how allergenic are these foods?

I have some jars of baby food that don't show up on my lists of
commonly- and rarely-allergenic foods. Do any of you know how
allergenic these are? (OK to eat now at 9 months, wait until a year,
wait until adulthood...)

green beans
prunes
peas
spinach
potatoes

We're being fairly cautious about allegies (family history) but so far
everything's been fine.
