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.

Amaryllis

Atlas is one of those names that was previously thought too powerful for a baby boy, who would have to be strong enough to carry the world on his shoulders. Now Atlas has joined the pantheon of Greek and Roman god and goddess names in the realm of possibility, along with Mars, Zeus and Apollo.

 Atlas was one of the fast-rising names on the list in recent years in the USA, jumping from oblivion in 2012 into the Top 500 in 2015, and climbing several hundred places higher since then. Anne Heche was one of the first to make this audacious choice, but several celebrity parents have followed suit.

 As well as the mythological connection, Atlas is a cool geographical word name – perfect for the child of parents who love traveling or who hail from different parts of the globe.

Atlas

Avis is a bird name that's been in hibernation for awhile, possibly due to the car rental association, but it could make a return on the wings of Ava. Baldwin brother Daniel chose it for his daughter.
 Avis Everhard is the fictional narrator of the Jack London dystopian novel The Iron Heel. In the Harry Potter books, Avis is not a character, but a spell.

Avis

Although Greek in origin--in the fourth century, a bishop by that name established the principles of the Greek Orthodox Church--Basil for years took on the aura of aquiline-nosed upper-class Britishness of Sherlock Holmes portrayer Basil Rathbone, then spiced with the fragrant aroma of the herb that entered with the Pesto generation.
 Now, it's time to take a fresh look at Basil.
 Basil was on the U.S. popularity list quite regularly up till 1970, reaching a high of Number 328 in 1904. Its history includes several rulers of the Byzantine Empire and Eastern Orthodox saints, including one whose grandmother, father, older sister and two younger brothers were all saints as well.
 Basil has also been seen as a figure of fun, as in the manic Basil Fawlty in the British TV comedy classic "Fawlty Towers," in the Disney movie "Basil of Baker Street," and as Basil Brush and Basil Wombat in other kids' entertainment.
 The Russian version, Vassily, is another possibility.

Basil

One of the most usable of the pleasant, newly adopted nature/water names (like Lake and Ocean), especially in middle position. 
 There was a character named Bay Kennish on the show Switched at Birth; conservative political commentator Bay Buchanan was born Angela Marie.
 Other associations with bay are the bay laurel tree, prized since ancient times for its medicinal and culinary (bay leaves!) properties, and the reddish-brown color usually applied to horses.

Bayou?  No, but it sounds the same, and since both the Indonesian name and the English word have appealing nature meanings, this is a perfect choice for the family that wants to bridge cultures.

Bayu

Originally a form of the saint's name Blaise, though now more likely to be a hot word name used for both sexes, though heavily weighted toward the boys. It has been in the boys' Top 1000 since the year 2000.
 br>On the pop culture side of things, Blaze Bayley is a singer and musician who has been connected to the bands Wolfsbane and Iron Maiden.

Blaze

Brisa is commonly used in Latino families, all but unheard of in others. 

Brisa

One of the rare cases where spelling a name with a y makes it less rather than more feminine.  Birdie might be the freshest choice in this aviary.

Byrd

Clay is a rich, earthy one-syllable name with a southern-inflected handsome-rogue image, featured on soap operas and reality TV. Its longer forms are Clayton and Clayborne. 
 There have been TV characters called Clay on The Wire, Sons of Anarchy, and 13 Reasons Why, and the name's most prominent recent bearers are American Idol Clay (born Clayton) Aiken and Green Bay Packer linebacker Clay (born William Clay) Matthews.

Clay

Doris had long been on our so-far-out-it-will-always-be-out-for-babies list, and seemed to be written there in indelible ink. But there are signs of a sea change, that Doris could profit from the revivals of Dorothy and Dorothea.
 She may not look it now, but Doris was considered the paragon of grace when she was part of a group of s-ending names (Phyllis, Frances) fashionable in the 1920s, and it got another shot of life when attached to the perky Doris Day in the fifties. In classical Greek mythology, Doris is the daughter of Oceanus, god of the sea, who gave birth to fifty golden-haired sea nymphs.

Doris

Unlike Amber, which is in decline, this name still has a bit of a glow left -- though confusions between the two will inevitably arise.

Ember entered the Top 1000 in 2009 and has risen steadily in the years since. The Em beginning can make it an original route to the nickname Emmy.

Ember

Irish town names are now fair game -- as are most other places with connections to Ireland -- but are much better suited to boys. 

Ennis

This phonetic Anglicization of the Irish name Eithne was made familiar by the single-named Irish singer and composer. St. Eithne was the daughter of a king and an early Irish convert to Christianity.

Enya

Flanna is an uncommon name for a red-haired girl, not as familiar -- or some would say, as pretty -- as its nickname, Flannery. 

Flanna

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.'

Forrest

The name of the Greek mythological earth goddess and universal mother; actress Emma Thompson stated that she was attracted by its ecological element, so other "green" parents may want to follow her lead.
 
Gaia is also an unrelated Latin name, the feminine form of Gaius. This is thought to come from gaudere, "rejoice".

Gaia

More uncommon and powerful than garden varieties like Rose and Lily. Named for Scottish botanist Dr Alexander Garden.

Gardenia

This name from the ancient Gilgamesh Epic would be a challenging choice; Hamish makes a more user-friendly option. 

Hanish

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

Hestia is the name of the Greek goddess of the hearth, home and chastity. Though Hestia has been long dormant as a name, it's a possibility for the parent in search of a classic name with deep roots that's also unusual. It's one of the <a href-="https://nameberry.com/list/624/gorgeous-greek-goddess-names-for-babies">Greek goddess names</a>that's both familiar and distinctive.

Hestia

Though it may not be as sweet and gentle as, say, Violet, the purple-hued Hyacinth still might hold some appeal for the parent seeking a truly unusual flower name. 
 
In Greek mythology, Hyacinthus was a Spartan youth accidentally killed by Apollo, from whose blood sprang a beautiful and fragrant flower, and it is also the name of several saints; Hyacinth became exclusively female in the nineteenth century. To the ancients, Hyacinth was, in addition to being a bluebell-like blossom, the name of a precious stone.
 
Hyacinth Bridgerton is the youngest child of the fictional Bridgerton family, named in alphabetical order from A-H. There is a character named Hyacinth Robinson in Henry James's The Princess Casamassima and Hyacinth Bucket is the social-climbing character on the British sitcom Keeping Up Appearances, with sisters named Daisy, Rose, and Violet. To underscore her pretentiousness, Hyacinth Bucket insisted that her last name be pronounced as "bouquet".
 
You might also consider the Spanish version, Jacinta.

Hyacinth

Io may be one of the slightest names in the book, but there aren't many two-letter names with as much substance as this Greek mythological example.  Io, a name used for the largest moon of Jupiter, was in classic myth raped by Zeus and escaped from him by changing herself into a cow. 

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 P. 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.

Juniper

Laguna Beach is a famous California spot -- though there's "goonie" teasing potential.

Laguna

The name of the Roman god of war began to sound less intimidating when Erykah Badu gave it to her daughter, and musicians Thomas and Bruno Mars (the latter born Peter Hernandez) have given it a modern edge. Mars actually could make a pleasant, planetary middle name for either sex.
In Roman mythology, Mars was the god of not just war, but also agriculture, and was more down-to-earth and less cold and ruthless than his Greek counterpart Ares. He was considered a father of Rome, as he was the father of mythical founder Romulus.

Mars

Feminine spin on Moses and European river name that's also the name of a wine. 

Moselle

Maren, Marin

Unlike Pearl and Ruby, this is one gem name suited for boys, the final x making it sound strong and virile. Musician Iggy Azalea chose the name Onyx for her son.

Onyx

This may be a bit quirky to make it as a name, especially in first place.  If you love it, you might try it in the middle.

Quartz

One of the many variations of Silvanus, the name of the Roman forest god, and a little-used member of the freshly stylish Sylv- family of names. Silvan is the sleek German and Dutch form. Given to less than 100 boys each year in the US, it's nevertheless in the Nameberry Top 500.

Sylvan

Thames

This Indian name with a Slavic sound definitely has potential. 

Varsha

This name of a showy, lemony plant makes an unusual entry into the name garden. 

Verbena

Wade has never been outside the US Top 1000 for boys - there's a reason for that. It has a clean spelling, fresh sound and is neither too trendy (unlike Kade or Cade) or too old-school (like Richard or Albert). We think Wade is a winning name.

Wade

Zephyr may not be a name often heard in the U.S., but its variations are used throughout Europe. Zephyrine, a cousin in sound and feel if not in fact to such lovely names as Severine and Seraphina, has distinctive possibilities.
