You can ride one, you can use it as a baby name – or, as is often the case, both! Harley is currently trending up for girls and down for boys in the US, although it remains predominantly masculine in the UK. A lesser-used -ley ending choice for boys, Harley has a current sound but an old-school biker appeal.

Acacia is an attractive, rarely used Greek flower name enhanced by its popular beginning-and-ending-with 'a'-construct, and is gradually beginning to catch on as a new member of the stylish girl names starting with A.

An x makes any name cooler, so that Baxter has a bit more pizzazz than the original Baker. Baxter had some currency as a first name a century ago--it was on the popularity lists sporadically from 1880 till the 1920s, peaking at Number 515 in 1886-- which means it's just about due for a comeback. And we can see Bax as a worthy follow-up to Max and Jax.

Azalea is one of the fresher flower names, along with Zinnia and Lilac, that are new to the name bouquet — in fact, it entered the Social Security list for the first time in 2012. So if Lily and Rose are too tame for you, consider this brilliant pink springtime blossom with a touch of the unusual that has been growing in popularity.

Coco came to prominence as the nickname of the legendary French designer Chanel (born Gabrielle) and has lately become a starbaby favorite, initially chosen by Courteney Cox for her daughter Coco Riley in 2004. At first it was the kind of name that the press loves to ridicule, but we predict Coco's heading for more broad acceptance and even popularity.

The name Barney is hot among hip Londoners and it has been above the Top 500 in the UK since 2012. You can see why - it's got a friendly happy sound and a lovely meaning and is more easily worn than Barnabas. However, Barney is a more difficult sell in America, due to Barney the Dinosaur and Barney Gumble, the loveable lout from The Simpsons. In the positive column for Barney are jazz clarinetist Barney Bigard and guitarist Barney Kessel. For those who love the name but can't get past the dinosaur, may we suggest the related names Bernard or Barnaby?

This evocative green nature name, heard much more frequently as a surname, is associated with playwright Moss Hart (born Robert), who co-wrote (with George S. Kaufman) such enduring Broadway comedies as The Man Who Came to Dinner and You Can't Take it With You.

A Native American tribe name which is found in the names of two US states, Dakota was one of the first trendy nineties place names, but is now flagging a little in popularity. The cultural question around using a Native American tribe name as a baby name may be partly to blame.

Once a macho biker name, Harley is now showing its softer side. In the UK, Harley is predominantly masculine, but it's currently more popular for girls than boys in the US.

Florence, Flora, and a whole plethora of botanical names are in style at the moment, but simple Flower remains rare. Perhaps it's the association with the little skunk in Bambi, or because it rhymes with flour used for cooking, but with Clover and Meadow in the charts, perhaps Flower might be one to reconsider.

Similar in sound to Harley, Marley, and Arlo, this surname-style name is familiar in Brazil and a Top 1000 choice in England and Wales. Pronounced as AHR-lee in English and ahr-LAY in Latin America, it may be a habitational name, relating to rabbits, hares, or eagles, depending on what Old English root you follow, though it may also relate to the names Arlette, Arleth, and Arlington, lending it the meaning "noble".

This name made it into the Top 1000 for the first time in 2013, one of only four girl names starting with O to rank that high. A decade letter, it's aiming for the Top 100.

Bunny may be adorable, but is it really enough of a name for your daughter? Plus if Buffy is fluffy, what would that make Bunny?

Windswept and dramatic, but perhaps asking for trouble. Quite popular in Denmark and Sweden, where it derives from Stromr, which is a fairly common surname.

Herbie is a diminutive form of Herbert, a Germanic name combining 'hari' (army) and 'berht' (bright), meaning 'bright warrior' or 'illustrious soldier.' Popularized in the mid-20th century, Herbie gained notable recognition through jazz musician Herbie Hancock and the fictional Volkswagen Beetle in Disney's 'The Love Bug' films. The name has a friendly, approachable quality with a vintage charm that evokes mid-century Americana. Though its popularity has declined since its peak in the 1950s and 60s, Herbie retains nostalgic appeal as a nickname. It exemplifies the trend of shortened, affectionate forms that became independently used given names in their own right.
