A quaint and quirky flower name, until recently considered a bit too prim for most American classrooms but brought back to life in recent years by the attractive character of Primrose "Prim" Everdeen in the Hunger Games series. In the Top 300 girl names in England and Wales and on Nameberry, Primrose remains rare in the US, but is made more accessible by a raft of sweet nickname options, including Rosie and Posy.

Among a small shower of rain-related names, this pure version can have a cool, refreshing image.

There's definitely a cold front of names for winter babies moving in, with Summer, Spring and Autumn giving way to Winter--plus North, January, Frost--and Snow. This name feels brisk, fresh, pure, evocative -- and magical. A haunting middle name choice.

The girls have dibs on Spring, Summer, and Autumn, leaving this name evocative of snowy landscapes as the one possible seasonal choice for boys. And naturally, it's one of the most obvious names for winter babies.
