Ash has Southern charm plus the arboreal-nature appeal. Plus your little boy will prize Ash as the name of the hero of the Pokemon cartoons. Ash can also be a dashing short form of Asher, Ashton, or any other "Ash" name.

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 has been steadily climbing ever since. It currently peaked in 2022 when it rose to the Top 200, as more parents respond to the appealing 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. It entered the UK Top 100 for the first time in 2023.

Birch is a rarely used nature name that calls to mind the lovely image of the tall, strong but graceful white-barked tree. 
 The best known bearer of the name is former high-ranking Democratic Senator Birch Evans Bayh, who carried the name of his father and was the principal Senate sponsor of the Equal Rights Amendment.
 The birch tree has many notable qualities and uses &mdash; including the making of furniture, paper, canoes, and drums, is considered the national tree of Russia (where it used to be worshiped as a goddess), the state tree of New Hampshire, and has spiritual significance in several cultures.

Cedar is, like Ash, Oak, Pine and Ebony, one of the new tree/wood names that parents are starting to consider; this one is particularly aromatic.
 In the Bible the cedar is mentioned in Psalm 92:12: "The righteous shall flourish like the palm tree and grow like a cedar in Lebanon." The Lebanon  Cedar was used to build King Solomon's temple in Jerusalem, and there are now several hospitals called Cedars of Lebanon, plus a U2 song by that name.
 A contemporary bearer of the name is the jazz pianist Cedar Walton, while Cedric and Cypress are similar options.

Cedar

A sweet and rare spice name, which made its first and only appearance on the US baby name charts in 1969 – the year Neil Young's song "Cinnamon Girl" was released.

Crimson could be a possible competitor for Scarlett's success, though it's lacking that Johansson charm.
 
Crimson tends to be disproportionately popular in Alabama — the University of Alabama's athletic teams are called Crimson Tide.

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

Fox is one animal name backed by a longish tradition, and then popularized via the lead character Fox Mulder on X Files. Fox is simple, sleek, and a little bit wild, and could make an interesting middle name.
 It was reported that the TV character's first name was not a tribute to the Fox network which aired The X-Files, as often assumed; show creator Chris Carter said he had a childhood friend named Fox. Fox was one of the fastest-rising boys' names of 2016, perhaps because of the popularity of the X-Files revival.

Originally a unisex nickname for a redhead -- red hair is called "ginger" in Britain -- or for the name Virginia, Ginger perennially wears pink gingham and spike heels.

Juniper is a fresh-feeling nature name -- it's a small evergreen shrub -- with lots of energy. A new favorite of fashionable parents, Juniper joins such other tree and shrub names as Hazel, Acacia, and Willow. 
 
Juniper has an interesting variety of associations -- it's mentioned in the Old Testament, was used in Renaissance paintings to represent chastity, has berries used to flavor gin, and Juniper is the Saint of Comedy. A male St. Juniper was a follower of St. Francis of Assisi. 
 Goodnight Moon and The Runaway Bunny author Margaret Wise Brown sometimes used the pen name of Juniper Sage. And in the Junie B. Jones kids' books, Junie's full name is Juniper Beatrice. There also have been Junipers is cartoon series (The Life and Times of Juniper Lee) and comic strips as well.
 
The name got something of a hippieish vibe via the 1969 hit Donovan song, 'Jennifer Juniper.'
 
Juniper entered the U.S. Top 1000 for the first time in 2011 and has risen to the Top 150.

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..

The graceful, natural image of the verdant shade tree transcends any connection with President Johnson.
 A sturdy tree that can live for centuries, Linden was actually quite a popular boys' name from the 1930s to the 1960s--as was the presidential spelling Lyndon--but has now become unisex.

Linden

Magnolia, a sweet-smelling Southern belle of a name made famous via the iconic Edna Ferber novel and musical Showboat, is one of the latest wave of botanical names, along with unexpected blossoms Azalea and Zinnia. It is named for French botanist Pierre Magnol.
 Magnolia has been chosen for his daughter by Adrian Young of No Doubt—which happens to be a fabulous baby-naming consortium as well as a great musical group.
 In Showboat, the Magnolia character goes by nicknames Noa, Nollie, and Maggie.
 Magnolia charted on the popularity list almost every year from 1880 to 1940, topping at Number 420 in 1909—but it's now making a comeback.
 Magnolia Breeland is a character on the TV show Hart of Dixie, who happens to have a sister named Lemon and a father named Brick.
 Maminydjama Magnolia Maymuru is an Indigenous Australian model.

Maple is one of those sweet-spot word names that sounds so almost name-like that it doesn't feel outlandish or strange, despite its relative newness as a given name. Just as Juniper is adjacent to June or Pippa, Clover like Chloe or Clara and Ember like Emma or Ebba, Maple is enough like Mabel, Maisie and Mae that it blends in well and has a touch of borrowed vintage charm.
 
Quietly used since the 1890s - yes, really - Maple has been rising up the charts in recent years. Currently given to around 180 girls each year, it ranks similarly to Marjorie, Emilie, Mariel, and Rue. Jason Bateman and Amanda Anka named their daughter Maple Sylvie in 2020, which has shone a spotlight on the name.
 
The name appeared very briefly in the US Top 1000 back in 1902 and there's even a poem about a girl called Maple by Robert Frost which dwells on the significance choosing a name for a child. Also associated with strength and endurance, Canada, syrup and pancakes, autumn and shades of red, we predict Maple will continue to rise in coming years.

Mila is a popular name that took a 125 year nap, ranking in the Top 1000 in 1881 and then not ranking again until 2006, after actress Mila Kunis appeared on That 70s Show.
 
Ukrainian-born Kunis was named Milena, and indeed Mila originated as a short form for names such as Ludmila, Milena, and Milica. Mila can be a nickname for any name containing the element mil, meaning "gracious" or "dear." 
 
Mila has ranked in the Top 100 in the US for a decade now, and is firmly established as a modern classic along with popular sister Mia. Mila has also found a good measure of international popularity, ranking highly throughout the English-speaking world and in several Eastern European countries along with Germany, Switzerland, and even Chile.
 
It's also a versatile nickname: former President Bush's daughter Jenna named her daughter Margaret Laura, after the child's two grandmothers, called Mila.

The menu of usable month names seems to expand every, well, month, with such choices as November, October, and January joining more established names like April, May, June and August. Logical November nicknames include Nova, Novi, or Ember, making this a natural (if adventurous) choice for a baby girl. November is also, obviously, one of the perfect <a href="https://nameberry.com/list/605/names-for-november-babies">names for November babies</a>.

November

Oak, a symbol of solidity, strength, and longevity, is joining Cedar and Pine as a viable name, one that would work especially well in the middle.
 If you'd prefer to take the longer route to the name, you can consider the surnames Oakes or Oakley.

As sturdy as Oak, but with stronger roots as a first name, Oakley ticks lots of boxes for modern trends. With its unisex vibe, it's nature-based meaning, it's surname-y feel, and it's popular -lee ending, it's not wonder Oakley is on the rise. 
 
In the US, it's been in the Top 1000 consistently since 2011 and now sits comfortably in the US Top 400 for boys and in the Top 200 for girls. Meanwhile, across the globe, Oakley is Top 100 boy name in the New Zealand and a Top 50 choice in the UK. 
 
Though it may sound like a modern unisex invention, Oakley was actually used as a boys' name in the US at the end of the 19th and early 20th centuries. While it did become an obscure choice until it was revived in the 2000s, it was nevertheless consistently but quietly used in the intervening years
 
Right now, for boys, Oak variations Oakland, Oaklen, and Oaklee are also quite popular and S-ender Oaks or Oakes are gaining in popularity too. Combine this with all the girls called Oakley, Oaklynn, and Oaklee, and it begins to feel much more popular than its ranking might first suggest.

Oakley

What is so rare as a month named June? October – and November and December – are a lot rarer. Brisk and substantial, they're so much more memorable and modern than April or May. October got its name via being the eighth month in the old Roman calendar. Some related, more feminine variations are Octavia and Ottavia.
 October was chosen by innovative author/editor Dave Eggers and wife Vendela Vida for their daughter. And Neil Gaiman wrote a story personifying the month in his collection Fragile Things entitled October in the Chair.

October

Among a small shower of rain-related names, this pure version can have a cool, refreshing image. 
 Richard Pryor named his now-grown daughter Rain, and Rain is also one of the nature-named Phoenix family siblings. More recently, 24 actress Marisol Nichols named her daughter Rain India.
 Rain also makes a nice nature middle name--Brooke Burke called her daughter Heaven Rain.
 If you want to embellish this simply spelling (and alter the meaning), you might also consider Raine, Raina, Rainn, Rayne, Reine or Reign, the middle name of Willow Smith. Or you could take the Holly Madison route all the way to Rainbow.

Rain

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.

Parents are beginning to turn away from springtime months like April and June and are moving toward the cooler and crisper three-syllable September, October, November, and December. 

September

Sorrel is a gentle, amber-hued herbal and autumnal name that's used most often to describe the color of a horse. Sorrell is a variant spelling. Both make excellent <a href="https://nameberry.com/list/351/names-for-autumn-babies">names for autumn babies</a> and can be used for either gender.

Wolf is a name with a split personality. It can be seen as one of the fierce animal names, like Fox and Bear and Puma, with a touch of the werewolf, or it can be viewed as a quieter, Wolf Blitzer kind of name, fairly common in German (where is pronounced Vulf) and Jewish families, sometimes as a short form of Wolfgang, or even Wolfram or Wolfhart.

 CNN newscaster Blitzer inherited the name from his grandfather. Other Wolfs of note include British screenwriter Wolf Mankowitz, who was instrumental in the early James Bond films, painter Wolf Kahn, and the hero of Jack London's 1904 novel The Sea-Wolf, Wolf Larsen.

 
Despite all it has going for it, Wolf is relatively rare and has never been given to more than 80 babies in a single year. But now that Kylie Jenner and Travis Scott chose it for their infant son, Wolf is primed to climb the charts.

 Spelling variations Wolfe or Woolf push it into surname territory, while nickname Wolfie definitely domesticates it.
