Nature Names Chosen by Celebrities

Most of the notable Rivers have been male, but this nature name certainly flows as well for a girl. The name River is still rising for both genders, with about 3500 baby boys receiving the name last year vs. 1900 baby girls.

Sky is an ambigender nature name that was first legitimized as the character of Sky Masterson in the 1950 musical Guys and Dolls, played in the film version by Marlon Brando. It's a name we appreciate for its clear, wide-open feel, less hippyish than others like Rainbow and Starlight, and makes an appealing middle name possibility.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Although most people don't think of it like this, Indigo might also be considered among the most stylish Greek baby names in use today. Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

The Forest variation of Forrest, used by actor Whitaker, nudges the meaning more toward the woods and away from the woodsman.

Nature names like Ocean and River are flowing back into favor, especially with nature lovers and green-oriented parents.

Though some may find such names rather harsh and severe, increasing numbers of parents are gravitating toward this kind of flinty, steely, stony single-syllable name.

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.

Though associated traditionally (and fashionably) with boys, it has been used occasionally for girls as well – by Garth Brooks, Nicolas Cage, and Facebook founder Mark Zuckerberg, for example. But August is used significantly more often for girls these days than traditional feminine variations Augusta and Augustina, and makes for a fresh twist on traditional month names like April and May, as well as an updated spin on season name Autumn.

One of the more unusual of the current crop of strong, single-syllable boys' names, evoking the images of both old-fashioned blackboards and modern stepping-stones and countertops.

Most parents today would prefer the softer-sell Stella. But Star has symbolic power related to Christmas, so this could make one of the perfect names for December babies.

Attracted attention as the stepmother of Princess Diana.

The original oddball celebrity baby name, via Frank Zappa's daughter Moon Unit, who claims she's always liked it.

There is a whole new species of bird names open to the baby namer, from the light and feminine Lark to the sleek and powerful Falcon.

Other wild animals like Fox, Wolf and Bear are catching on as baby names, and Tiger is a rarer option with several famous namesakes, including golf champ Tiger Woods, who was born Eldrick. Other famous Tigers include Indian actor Tiger Shroff, born Jai, and British actor Tyger Drew-Honey, who spells his name with a Y.

Colorful, yes, but also probably among the hippiest of hippie names. Holly Madison recently chose it for her little girl.

With other bird names such as Lark and Phoenix on the rise, why not chirpy Sparrow? Nicole Richie and Joel Madden named their son, born in 2009, Sparrow James Midnight.

Has an old-time country feeling, perhaps due to Ma Rainey, considered the "Mother of the Blues". This is the most popular spelling of the name, given to about 50 girls last year, with half as many called Rainy and a quarter named Rainie, the spelling used by Andie MacDowell for her now-grown daughter.

Stormi is like Sunni, with angst. If naming your child Storm or Stormy is asking for trouble, naming her Stormi -- as Kylie Jenner and Travis Scott did -- is asking for trouble of several different kinds. But we're sure she'll be adorable and as celebrity baby names go, this one is nearly normal.

An ubercool and mysterious name, brought to you by director M. Night Shyamalan.

While we don't see many parents adopting Otter as a name for their own babies, Zooey Deschanel put this one in the lexicon when she used it as a middle name for her adorably-named daughter Elsie Otter. Even in the celebrisphere, Otter is one of the most unique baby names we've heard.
