Which flower's name literally means "nose-twister"?

Grows well in Australia, wild in some places. Is a useful plant. The young green seed pods when pickled substitute for capers and the smaller green leaves and flower petals of many different colours add a peppery taste to a salad besides making it look 'tres exotic '

I love nasturtiums, their flowers, seed pods, leaves can all be eaten, so a joy for the eye and a delight for the palate.

never heard of it, but the name kind of gave it away.
