I have for a lady I garden for . I normally just pick the prettiest ones to save . They are larger the second year and flower sooner so I would say , yes.
I store mine in a cardboard box with wood shavings , in my unheated garage, pull them out mid/late April and pot up till late May then into the garden.
you can put them directly into the garden and cover them with mulch but they are much slower to sprout, and if they come up early and get frosted off they you have even a longer wait.
This info is from my zone 5 gardening experence .
Don't know your zone.
