Cassia is related to the cassia tree, which has yellow flowers and produces a spice that can be a substitute for cinnamon. Keziah, the name of Job’s daughter in the Old Testament, derives from the name of the plant as well. Cassia also has ties to the Ancient Roman name Cassius, an Ancient Roman family name meaning "hollow."

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.

Though perhaps not as currently stylish as Ruby, Jade, or Pearl, Amber has a colorful history (remember the notorious Forever Amber heroine?). Unfortunately, it does come with the "Amber Alert" connotation for modern parents (and their children).

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names. Grey/Gray is one exception, which could make for a soft and evocative—if slightly somber—choice, especially in the middle. Kaitlin Olson and Rob McElhenney named their son Leo Grey.

Emerald is the intriguing color and jewel name of the deep green stone treasured as far back as ancient Egypt — it's supposed to open one's heart to wisdom and to love and be good for strengthening relationships — which could make for an interesting, unusual name, particularly with the popularity of so many Em-starting names.

Esmeralda came into use as an applied use of the Spanish word for emerald, esmeralda. In the 1831 Victor Hugo novel Notre-Dame de Paris, also known as The Hunchback of Notre-Dame, the heroine was born Agnes, but called La Esmeralda in reference to the jewel she wears around her neck. The name Esmeralda got increased visibility via the Disney version of the story.

Infinitely preferable to the tease-inspiring English version of the word.

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 names for autumn babies and can be used for either gender.

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.

Greyson and Grayson, nephews of Jason, are both on the fast track. Both variations have made their way all the way up to the Top 100 since 2016. Gray/Grey makes a nice nickname. The name of the child in The Nanny Diaries is Grayer, and actor Tyler Christopher opted for the unusual spelling of Greysun for his son. Some parents are considering Grayson -- or Gracen or Gracyn -- for girls as an androgynous spin on Grace.

This Italian name could have a whole new life when viewed as a color name, however, it is traditionally a masculine form of Carmen, pronounced with three lilting syllables. Both provide an arty, distinctive feel, though in different ways.

Among the coolest of the cool color names, particularly popular with celebs as a unisex middle name. While most famous as the name of Beyonce and Jay-Z's daughter Blue Ivy, more than 60 percent of the babies named Blue are boys.

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 color name, a gemstone name, and an ocean-inspired choice, Coral has a lot going for it with its sharp C sounds yet sweet vintage feel. Unlike Scarlett or Violet, however, it is only quietly used in the US these days, perhaps because of its similarity to more 'dated' Carol.

Azure is a colorful gender-neutral choice, currently used equally for baby girls and boys in the US. It refers to a specific shade of blue seen in a cloudless sky. Elon Musk revealed Azure to be the name of his daughter with Shivon Zilis, twin sister to Strider.

Even among the range of blue names on the current baby naming palette -- Blue itself, Azure, Cerulean, Teal, Aqua, Cyan, Indigo -- Cobalt remains the most unusual, not to mention the most masculine.

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names. Gray (or Grey), is one exception, which could make for a soft and evocative--if slightly somber-- choice, especially in the middle. Kaitlin Olson and Rob McElhenney recently named their son Leo Grey.

Bruin is the Old English term for bear, taken from the Dutch word meaning brown. Bruin might be a sports fan's choice or an animal name in hiding. As a kind of hybrid of Roone and Bruno, it's definitely got some cool.

As flower names become more unique, so can gem names move beyond Ruby and Pearl to names like Topaz, Sapphire, and Peridot. Amethyst, the purple birthstone for February, has never been in the Top 1000, but could have some appeal, joining similarly-hued Violet and Lilac, all of which make great names for Aquarius babies or names for February babies.

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