If you love both <a href="https://nameberry.com/list/317/unique-baby-names">unique baby names</a> and flower names for girls, Amaryllis might be a perfect choice for you. 

A showier flower name than Lily, but in the same botanical family, Amaryllis is not as outre as it might at first sound. It was used in Greek poetry as the appellation of pure pastoral beauties; Amaryllis is the heroine of Virgil's epic poem Ecologues, after whom the flower was named. 

Other references are characters in the George Bernard Shaw play Back to Methuselah and The Music Man. James Bond-creator Ian Fleming had a half sister named Amaryllis Marie-Louise Fleming, who was a noted British cellist.

Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry. 
 Arlo is even more popular in the UK, Australia and New Zealand. Arlo is also one of the top baby names among Nameberry's visitors from leading US cities.

 
Once strongly associated with shaggy singer Arlo Guthrie, Arlo has an animated and cheery feel, thanks to its upbeat o ending. It was chosen by Toni Colette for her son in 2011, which brought the name back into the spotlight. Previously, Arlo was in regular use in the first half of the twentieth century—it was Number 667 in 1915, for example, but it had dropped off the charts in 1944.
 Arlo has many possible derivations along with its Irish and English roots. It may be a shortened form of the Italian name Carlo or the Spanish Carlos, and in Basque-speaking regions it is the word for area. In English, Arlo was used as a place name, Arlo Hill, by Edmund Spenser in his epic poem The Faerie Queene and is thought to derive from the Celtic word Aherlow, meaning "between two highlands."

 A growing number of girls are also named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this name more into smart surname territory.

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.

As trendy as the chic Colorado ski resort and film festival, Aspen is fast becoming more popular for girls than for boys, but this nature name would work equally well for either.

Aveline is a name that's long been an obscure cousin of more widely-used choices, but may come into its own riding the tail of the megapopular Ava, which may derive from the same root.

 Although Aveline is a cognate of the French word for "hazlenut", the name actually derives from an obscure Germanic root, the meaning of which is not clear. Theories include "desired, wished for" and "water, island".
 
Aveline is different enough to sound distinct, but be warned: You will forever be explaining that no, it's not Adeline, not Evelyn, and so on.

Camellia is a rare flower name with distinct roots related to the Camille/Camila group and has varied associations to the moon, water, wealth, and perfection. It could be thought of as a floral replacement for Amelia. 
 The attractive flowering tree was named by Linnaeus for the Moravian Jesuit botanist Georg Joseph Kamel and has been used, if sparingly, as a first name since the 1930s.
 In the language of flowers, the camellia denotes admiration and perfection, and it's the state flower of Alabama. The Dumas novel The Lady of the Camellias is the basis of the opera La Traviata and the Garbo film Camille.

Camellia

With other fruity names like Clementine, Olive and Plum ripe for the picking, sweet Cherry remains remarkably underused: just 27 baby girls received the name in 2017, down from 343 at its peak in 1948. The unsavory slang meaning no doubt goes a long way towards explaining its fall from grace.

Cherry

One of the rarest of the flower names, that of the blossom celebrated in Japan as a symbol of the sun and a possible object of meditation. One of the rare flower names counted among <a href="https://nameberry.com/list/351/names-for-autumn-babies">names for autumn babies</a>, Chrysanthemum is also one of the most unusual nature-themed <a href="https://nameberry.com/search/girls-names/c">girl names starting with C</a>.

We all heard it on Seinfeld as the long-concealed first name of Kramer, then considered a punchline. Now some pioneering parents are embracing this expansive Greek name, which makes a creative and cool choice for a baby. Influential celebrity couple Scarlett Johansson and Colin Jost chose it for their son, born in 2021, which will likely drive Cosmo up in popularity. In the UK, it currently ranks within the Top 1000 boy names and is trending upwards.

 In literature, Baron Cosmo Bradwardine is a character in Sir Walter Scott's novel Waverly and Cosmo Topper is the befuddled banker in Thorne Smith's humorous novel Topper. In modern times Cosmo has become the short form for Cosmopolitan – both the magazine and the cocktail. And for those wishing to honor a medic in the family, Cosmo is also the name of the Arabian-born patron saint of doctors.

Daisy, fresh, wholesome, and energetic, is one of the flower names that burst back into bloom after a century's hibernation. Originally a nickname for Margaret (the French Marguerite is the word for the flower), Daisy comes from the phrase "day's eye," because it opens its petals at daybreak.

 Daisy has a colorful literary and pop culture history – as the innocent Daisy Miller in the Henry James novella, as Daisy Buchanan, the hero's object of desire in The Great Gatsby, and as many movie and TV characters, including in L'il Abner and The Dukes of Hazzard, as the older Daisy in Driving Miss..., as well as Julia Roberts's character in her breakthrough movie, Mystic Pizza.

 Meg Ryan has a daughter named Daisy True, chef Jamie Oliver has Daisy Boo, and Katy Perry and Orlando Bloom recently named their daughter Daisy Dove.

Fleur is a generic, delicate flower name that emigrated into the English-speaking world when John Galsworthy bestowed it on one of the Forsytes in his celebrated saga. More recently, there was Fleur Delacour, a French witch and the Beauxbatons champion for the Triwizard Tournament in Harry Potter. 
 Fleur is currently in the Top 100 in Belgium and the Netherlands, home of the tulip and other fleurs.

Forrest is one of the earliest appealingly sylvan, outdoorsy choices, borne by newsman Sawyer, actor Whitaker, and football Hall of Famer Gregg. Forrest Gates was a character on "Buffy the Vampire Slayer."
 Forrest was steadily on the US popularity list until 2003, reaching a high of Number 175 in 1913, and then received a somewhat surprising blip after the release of "Forrest Gump." It started rebounding again in 2013, when it reentered the Top 1000 as one of the fastest-rising names on the list.
 Early Forrests were named in honor of Confederate General Nathan Bedford Forrest, head of a famous cavalry force, who advised 'Git there fuster with the mostest men.'

Hollis is a rugged, gentle and quietly used name, given to over 200 boys and 150 girls each year in the US. In 2023, it became one of the newest entries to the US Top 1000, where it fits in with the surnames-as-first-names trend, and other familiar choices like Ellis, Silas, and Holden. 
 
Derived from the English surname meaning "near the holly bushes", it has a number of notable connections. Hollis Thompson is a professional basketball player; Hollis Watkins is a Civil Rights activist in Mississippi; Pete Hollis was a community folk hero; and "The Ballad of Hollis Brown" is a popular Bob Dylan song.
 Combining woodsy sounds and outdoorsy vibes with a surname-y and smart style, Hollis feels sleek and preppy, but adventurous and spirited too.

Iolanthe is known primarily through the 1882  Gilbert & Sullivan operetta of that name, in which the title character is a fairy. Iolanthe is a softer version of Yolanda, and is the kind of multi-syllabic classical name once considered too weighty for a modern baby girl, but now within the realm of possibility--this one as a dramatic twist on Violet. The biggest drawback is its variety of legitimate pronunciations in English.

Iolanthe

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.
 
Iris is directly derived from the Greek word iris, meaning "rainbow." In Greek mythology, rainbow goddess Iris was a messenger for Zeus and Hera who rode the rainbow as a multicolored bridge from heaven to earth. 
 The botanical iris also carries evocative symbols. In ancient times, the Iris was considered a symbol of power and majesty, the three petal segments representing faith, wisdom and valor. This image led to the naming of the colored part of the eye.
In the contemporary world, Iris has amazing international versatility, ranking highly throughout the English-speaking world as well as in a diverse range of countries from Spain to Slovenia, France to Sweden.
 Part of Iris's rise is due to its celebrity power: Jude Law and Sadie Frost, Judd Apatow and Leslie Mann, and Renee O'Connor all chose Iris for their daughters.
 A notable modern bearer was the prolific British novelist Iris Murdoch. Frequently seen on screen, characters called Iris have been played by Jodie Foster, Jane Fonda and Kate Winslet, and Iris Chase is the narrator in the Margaret Atwood novel The Blind Assassin.

The quirky, offbeat and energetic botanical name Ivy is enjoying a deserved revival, propelled even higher by its choice by high-profile parents Beyonce and Jay-Z for daughter Blue Ivy. Ivy is also traditionally used at Christmas, make this one of the perfect <a href="https://nameberry.com/list/577/names-for-december-babies">names for December babies</a>.
 Ivy is derived from the name of the ivy plant, which got its name from the Old English word ifig. Ancient Greeks presented an ivy wreath to newlyweds as a symbol of fidelity. In the language of flowers, Ivy signifies faithfulness.
 British novelist Ivy Compton-Burnett is a notable namesake and Ivy Baker Priest served as U.S. Secretary of Treasury. Another association is the prestigious Ivy League. 
Ivy has been a favorite of scriptwriters—she's appeared on everything from 90210 to Gossip Girl, Dollhouse to Downton Abbey, and is the name of a 1970's American Girl doll.

Lilia is pretty double L name that makes for sparkly, floral choice with plenty of international flair. More distinctive that Lily, less popular than Liliana, Lia, and Lilian, Lilia was a new entry to the US Top 1000 in 2023.
 
A truly cross-cultural choice, the lilting Lilia is heard among the Russian, Spanish, Hebrew, and Hawaiian communities and currently ranks in the UK, France, Poland, and Brazil. It has a number of spelling variations too, including Liliya, Lilya, and Lilja, meaning it ranks in Iceland and Finland too.

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.

This Greek flower and mythological choice doesn't make it into the pantheon of possibilities because of its association with narcissism. But narcissa is December's flower of the month, so Narcissa and Daffodil theoretically make perfect <a href="https://nameberry.com/list/577/names-for-december-babies">names for December babies</a>.

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.

Orchid is a hothouse bloom that has not been plucked by many modern baby namers — yet. In the language of flowers, orchids symbolize love, beauty, and sophistication. 
 In a 1926 silent comedy, femme fatale Gloria Swanson played a burlesque chorus girl named Orchid Murphy.

Poppy, unlike most floral names which are sweet and feminine, has a lot of spunk. Long popular throughout the rest of the English-speaking world, Poppy is finally starting to rise toward the top in the US, where it entered the Top 1000 for the first time in 2016.

 British TV chef Jamie Oliver used the name for his eldest daughter, Poppy Honey Rosie, as did Anthony Edwards, Jessica Capshaw, and Anna Paquin and Stephen Moyer. A notable adult Poppy is Australian Without a Trace star Poppy Montgomery (full name Poppy Petal Emma Elizabeth – she and her sisters are all named after flowers: Lily, Daisy, Marigold and Rosie).

 Due to the flower's bold crimson color, Poppy makes an especially good choice for a redhead. In the UK, it is a traditional <a href="https://nameberry.com/list/605/names-for-november-babies">name for November babies</a>, due to the flower's association with Remembrance Day (Nov 11), honoring the memory of members of the Armed Forces who have died in the line of duty.

 Other Poppy-like names to consider: Pippa, Piper, Posey and Petal.

No, the pronunciation--ro-SHEEN--isn't immediately obvious to the non-Gaelic viewer, but the sound of this shiny Irish version of Rose is pretty enough to make it worth considering. Very popular in its native Ireland, it's one of many <a href="Irish girl names https://nameberry.com/list/753/best-irish-girl-names">Irish girl names</a> finding a wider audience. Earlier generations Anglicized at as Rosaleen, but we stay stick to the original.
 The name has been associated with a 16th-17th century poem called Roisin Dubh (Dark Little Rose), the eponymous heroine of which is usually regarded as a personification of Ireland.
 Singer Sinead O'Connor has a daughter named Róisin.

Roisin

Rose is derived from the Latin rosa, which referred to the flower. There is also evidence to suggest it was a Norman variation of the Germanic name Hrodohaidis, meaning "famous type," and also Hros, "horse". In Old English it was translated as Roese and Rohese.
 
Rose, one of the old-time sweet-smelling flower names, has had a remarkable revival—first of all as a middle name—with parents (e.g., Jennifer Garner & Ben Affleck, Jon Stewart, Eric Clapton, Ewan McGregor) finding Rose to be the perfect connective, with more color and charm than old standbys like Sue and Ann. At this point in time, though, some parents are finding there are too many roses in the middle spot of the garden.
 As a first name, Rose reached its highest point from 1896 to 1921, the early heyday of flower names, when it was in the Top 20, though it had been in use for centuries before. Rosy/Rosie is an irresistibly cheery nickname, very popular on its own in the UK. There are any number of Rose offshoots, including Rosa, Rosetta, Roseanne, Rosanna, Rosemary, Rosamund, Rosalind, Rosalie, and Rosina.
 Rose and Rosie have long been celebrated in song, and notable Roses range from Rose Kennedy to Rose Byrne, and on-screen Roses have featured in a range of films and TV shows, from Titanic to Harry Potter to Golden Girls.

Tansy is a flower name rarer than Rose, livelier than Lily and a lot less teasable than Pansy. 
 Tansy is a perennial herbaceous plant of the aster family that has clusters of small bright yellow blossoms. It was cultivated by the ancients for medicinal purposes, and has found a variety of other uses over the ages, associated with health and immortality.
 There have been a couple of eponymous novels titled Tansy, and it was the name of a character on Hart of Dixie,

Violet is soft and sweet, yet with a vivacious edge. Today, Violet is the top flower name for girls, outranking Lily and Iris in the Top 100, and the second most popular color name for girls after Scarlett. 
The violet is a delicate, sweet-smelling spring flower, associated with faithfulness and modesty, and also the seventh color of the rainbow, named after the flower’s vivid purple hue.
A name that dozed quietly for decades, Violet was popular a hundred years ago, then began its steep descent, bottoming out in the early 1980s. But it started rising again in the late 1990s and climbed even more sharply after Jennifer Garner and Ben Affleck chose it for their daughter in 2005. 
It is now well-used by celebrity parents, including the daughters of Christina Milian, Emily Strayer, Nathan Followill, Dave Grohl, and Emily Blunt. 
In children’s literature, Violet Beauregarde in Charlie and the Chocolate Factory does it no favors, but Violet Baudelaire in Lemony Snicket's A Series of Unfortunate Events</em, and Violet Parr in the animated film The Incredibles, have helped to redeem it for today’s parents.
Violet is also the first name of Dowager Bridgerton, the matricarch in the show Bridgerton, a reminder of the name’s genteel, vintage side. 
International variations of Violet include Viola, as in the heroine of Shakespeare’s Twelfth Night, French Violette, and snappy Violeta and Violetta.

 In the language of flowers, Zinnias symbolize remembrance.
