Depiction in the series
Lemon Hearts is commonly featured as a background pony. During running sequences, her eye color turns blue and her eye style often changes to one resembling Rarity's.

She makes her first appearance in Friendship is Magic, part 1 in Canterlot. She appears before Twilight Sparkle, alongside Twinkleshine and Minuette, while carrying a present on her back. She has no spoken lines in the scene, but she receives Twinkleshine's remark about Twilight when the studious unicorn turns down the offer to join them at Moondancer's get-together. Later in the episode, she appears at Pinkie Pie's party in Ponyville's library and is among the ponies who visually yell "Surprise!" to Twilight. Since then, Lemon Hearts has been a common sight in Ponyville.

She attends the Grand Galloping Gala in The Best Night Ever and makes it into the V.I.P. section. She takes photos of Wonderbolts Spitfire and Soarin with fellow Gala attendees "Charm" and "Masquerade". In Putting Your Hoof Down, she offers two bits for the cherry Fluttershy wanted to buy for Angel's salad. In The Crystal Empire - Part 1, she is among the ponies at the Crystal Fair when Rainbow Dash flies back to the Crystal Empire castle with the flag. In Spike at Your Service she looks from the window as Spike slides down the roof. In Games Ponies Play she sells baked goods for "Cotton Cloudy".

Lemon Hearts appears in Princess Twilight Sparkle - Part 1, Flight to the Finish, Power Ponies, Rainbow Falls, Pinkie Pride, Simple Ways, Filli Vanilli, and It Ain't Easy Being Breezies. She appears in For Whom the Sweetie Belle Toils at the Cutie Mark Crusaders' play, having extended lines of dialogue. She also appears in Leap of Faith, Trade Ya!, Inspiration Manifestation, Equestria Games, Twilight's Kingdom - Part 1, and Twilight's Kingdom - Part 2.

Re-use of color
A few background ponies who share Lemon Hearts' color scheme appear in the series. In many crowd scenes, a pony with the same design as "Lavenderhoof" but with Lemon Hearts' color scheme appears off to the side, looking ahead diagonally. In Winter Wrap Up, a pony with the same design as Golden Harvest and Daisy, but with the aforementioned color scheme, plows the snow with the plant team.

A pony with a similar color scheme and name is Lemony Gem, a unicorn pony with the same design as Amethyst Star, Diamond Mint and Lyra Heartstrings who appears in The Ticket Master, Call of the Cutie, Green Isn't Your Color, The Best Night Ever and Sweet and Elite, usually wearing a pink saddle with a light pink skirt underneath. However, she is much more differentiated from Lemon Hearts due to her cyan eye color and different cutie mark, which is seen in The Best Night Ever.

Merchandise
A mini-figure toy named Lemon Hearts was released as part of the first wave of mystery packs in November 2010 and as part of the Toys "R" Us exclusive Friendship Celebration Collection. The toy uses the Rarity mold but features the show character's color scheme and cutie mark. Her name comes from the packaging of the toy releases. According to the back of the European mystery pack collector card, Lemon Hearts "is loving and kind". The description on the back of the Australia/U.S. mystery pack collector card adds, "She always takes time to show her friends how much she cares." The illustration on the front of both versions of the card depicts Lemon Hearts standing outside Carousel Boutique. The Friendship Celebration Collection toy package has a different description and reads, "LEMON HEARTS and PEPPERDANCE play together in a band!"

Lemon Hearts appears as one of the guests attending the wedding of Shining Armor and Princess Cadance in the My Little Pony First Look and Find book, with the same design as on the first collector card.

A second Lemon Hearts mini-figure toy and collector card pair is part of the eighth wave of mystery packs. Unlike the toys, the first collector card, and the First Look and Find book, this collector card features the show character's mane style. According to this collector card, "LEMON HEARTS always takes time to show she cares!"

A third Lemon Hearts mini-figure toy and collector card pair is part of the tenth wave of mystery packs, which has been displayed at the 2014 American International Toy Fair. This collector card uses the same mane style and description as the previous collector card.

Lemon Hearts is also named with a trademark symbol on her Enterplay collectible card game Canterlot Nights expansion set card, which attributes to Mint Jewelup the quote "Now if only every pony with 'Lemon' in their name was half as nice as Lemon Hearts..."
