Aspen is part of two groups of stylish and unique baby names: <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a> and place-names. The name of a graceful tree in the poplar family with heart-shaped leaves so delicate they quiver in the gentlest breeze, Aspen is also the name of a trendy Colorado ski resort. Aspen started as a unisex name possibility but now is much more frequently worn by girls.
 Aspen entered the popularity list in 1993 and is a good bet to start climbing higher as more and more parents respond to the appealing place and nature image it evokes.

Crisp and colorful, Autumn is the most popular season name now -- the only one in the Top 100 in recent years -- with Autumn's coolness only surpassed by Winter. Jennifer Love Hewitt named her daughter Autumn James.

Autumn is one of those unusual names that's been popular for many years without ever becoming wildly overused, which can be a real plus if you're looking for a name that's familiar without being too trendy.

Bjorn is one of the most recognizable <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>, thanks in large part to tennis great Björn Borg, winner of five consecutive Wimbledon singles titles and six French opens and something of a rock star figure.
 
Bjorn has been in use since the days of the Vikings, but got a boost in popularity when Borg ruled the courts. There have also been other notable Bjorns in various fields in Sweden, Norway and Germany, ranging from the first king of Norway to a member of the pop group ABBA.
 
And if you do pick this name for your son, your baby Bjorn can be carried around in a Baby Bjorn.

Bjorn

It's a nature name evocative of rushing waterfalls. But also a dishwashing detergent. 

Cascade

Colt is the kind of unconventionally macho name that is so trendy right now, because of or in spite of its association with horses and guns. 
 Samuel Colt was the inventor and industrialist credited with popularizing the revolver.
 Colt is a perfect jock name, associated both with Washington Redskins quarterback Colt McCoy and an entire football team, the Indianapolis Colts.

Colt

This appealing name has a good chance of catching on due to the popularity of Ewan McGregor, and the trend towards Gaelic names in general. Pronunciation is YOO-un.
 Ewan has a complex family tree, with connections to John, Owen, Hugh, Evan and Eugene. Other spellings are Ewen, Eoin and Euan.
 In Willa Cather's novel My Mortal Enemy, there is a character called Ewan Gray.

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. 

Falcon

The doe-eyed Fawn is as gentle and soft as the baby deer it represents. And much like that baby deer, it carries with it the potential of new life. Fawn was featured at the bottom of the Top 1000 throughout the '60s and '70s — around the same time that Bambi came into play. But unlike Bambi, Fawn maintains relevance in the 21st century, thanks to its warmth and ties to the natural world. We would love to meet more baby girls named Fawn.
 
Fawn would work as update to the now-dated Dawn, and is one of our favorite <a href="https://nameberry.com/list/479/middle-names-for-girls">middle names for girls</a>.

Of all the botanicals, Fern has been one of the slowest to move back from the front parlor into the nursery, despite the appealing girl character in the children's classic Charlotte's Web. Fern was most popular from the turn of the last century through the 1940s, reaching a high of #152 in 1916. We can certainly see her rejoining the long list of popular greenery names.
 
Reality TV stars Jessa Duggar and Ben Seewald recently named a daughter Fern, which could easily give it a boost.

Fern

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

Forest

Animal names are on the rise, especially more of the aggressive Hawk-Fox-Wolf variety than cute little Bunnys or Robins, and Hawk is a prime example. 
Hawk is more commonly heard as a surname, represented by uber-skateboarder Tony Hawk, a pioneer of modern vertical skateboarding. Variations include Hawke, as in actor Ethan, Hawks, as in Golden Age movie director Howard, Hawking, as in scientist Stephen, and Hawkins, as in musicians Coleman, Screamin' Jay and Sophie B, and was recently given to his baby boy by quarterback Tony Romo. There have been characters named or nicknamed Hawk in The Revenant, The Path and Robert B. Parker's Spenser novels. Hawk ranks at Number 699 on Nameberry.

Hawk

Heron may feel like a very usable nature name -- the heron is a long-legged wading bird -- but it was also the name of a 1st century Greek inventor and of an Egyptian saint. Highly unusual yet easy to understand and meaningful on several levels, Heron is a fantastic choice.

Heron

Lark is getting some new and well-deserved attention as a post-Robin and Raven bird name. Although it was first recorded as a name in the 1830's, it has never appeared on the Social Security list.
 'The Lark' was used as a nickname for Cosette in Les Miserables; Lark Voorhees was a star of Saved by the Bell, and Jennifer Connelly and Paul Bettany used Lark as the middle name of their daughter Agnes.
 
The expression "happy as a lark" gives this songbird name a cheery image, as well as a 'lark' being a synonym for a merry time..
 Larkin is a pretty extension, as is Skylark, which is rich in cultural associations: there's the Percy Bysshe Shelley ode To a Skylark and the jazz classic Skylark written by Johnny Mercer and Hoagy Carmichael..

Lark

Meadow's upward popularity trajectory certainly suggests that the name has transcended its connection to The Sopranos.. In the US, more than 750 baby girls were named Meadow last year, a number we expect to keep rising.

If it can happen to Scarlett (O'Hara) and Atticus (Finch), it can certainly happen to lovely pastoral Meadow.

Before we let go of the Sopranos connection, how perfect was it that Tony Soprano's daughter's name was Meadow, suggesting that the TV mobster was once a kinder, gentler young dad?

Meadow

Peregrine is considered to be an elegantly aristocratic name in England, but has never made it to the U.S., where it has been seen as extravagantly eccentric. In the new naming climate, though, it's not beyond consideration &mdash; in fact it's already been chosen by at least one Berry.
 The meaning of Peregrine, which was borne by several early saints, relates to the transitory nature of life on earth, having nothing to do with the peregrine falcon. In literature, it is best known from the central character of Tobias Smollett's novel Peregrine Pickle.
 Historically, Peregrine was the name chosen for the first English child born in the New World &mdash; actually on the Mayflower when it was docked in Provincetown.
 And there's always the Mad Men-era nickname Perry to make Peregrine more user-friendly.

Peregrine

Bird name Raven, once a symbol of pride for both African-American and Wiccan parents, is finding new life as a superhero name. Raven Darkholme is the real name of Mystique, heroine of the X-Men films played by Jennifer Lawrence. And there is another Raven superheroine in Teen Titans. Some parents may still choose Raven to signal black pride or mystical powers or maybe even Edgar Allan Poe fandom, but we are guessing most inspiration is coming from the comics.

Raven

Sage is an evocatively fragrant herbal name that also connotes wisdom, giving it a double advantage. It entered the Top 1000 at about the same time for both genders in the early 1990s, but it has pulled ahead for the girls. Toni Collette named her daughter Sage Florence.
 The Greeks and Romans wrote that the smoke from burned sage leaves imparted wisdom, and in the tenth century, Arab physicians said that sage brought about immortality, or at the very least, a long and healthy life.
 In Vampire Diaries, Sage is a beautiful vampire possessing super strength and speed.

Sage

With related choices such as Lark and Phoenix gaining popularity, why not Sparrow? Though it's usually thought of as a female name, Nicole Richie and Joel Madden chose it for their son.

Sparrow

Spring doesn't sound half as contemporary as Winter, which has become the cool season name. 

Spring

An ancient tree that figures in literature from Shakespeare to Harry Potter and is believed to possess magical powers, Willow is a lovely name, as graceful as its inspiration.
 Willow's use as a given name derives directly from the willow tree, whose name was derived from the Old English word welig, meaning "willow." Willow trees are associated with grace and elegance, which gave way to the adjective "willowy." Other names with meanings related to willows include Arava, Willoughby, Dozier, Wellesley, Selby, and Salton.
 
This elegant and charming nature name has been chosen for their daughters by Will Smith and Jada Pinkett Smith, Michelle Monaghan and Pink. It's been a fast riser in recent years, climbing along with other Will names Willa, William and Will, having taken off here a year after the character of Willow was introduced on Buffy the Vampire Slayer in 1997.
 
Willow is also popular in other English-speaking countries: Australia and the UK, Canada, Ireland, and Scotland.
 
The name has transcended its one-time hippie aura to move into the realm of reappraised and appreciated <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a>. The willow is believed by the Romani to possess the ability to heal the sick and rejuvenate the aged.
 
Pink was quoted as saying her choice was influenced by a willow tree she grew up near, and that it is the most flexible tree that nothing can break—no wind, no elements, it can bend and withstand anything.

Willow

Fresher, brisker and, yes, cooler than Summer or Autumn or Spring, Winter is now a full-fledged female choice, especially since Nicole Richie and Joel Madden used it for daughter Harlow's middle name, and Gretchen Mol picked it as her daughter's first, as did media mogul Sean Parker. Winter continues to be the preferred spelling and has risen in popularity significantly over the past few years.
 Although Winter entered the U.S. Top 1000 in 1978, it was been used as a first name as early as the seventeenth century.
 Some interesting international words for winter: Aeneva (Cheyenne, Native American), Cole (Chinook, Native American), Hima (Sanskrit), Jara (Hindi), Saradi (Hindi), Vandi (Kashmiri), Zaya (Old Persian) and Zima (Russian, Bulgarian).
