If you’re on the hunt for a birthday gift for your sister and aren’t sure where to start, let this guide serve as inspiration. From beautiful blooms tailored to her tastes, to personal birthday messages and practical presents she’ll actually use, we have plenty of ideas to inspire a smile on her big day.

Send flowers that speak her language


We may be biased, but we think it’s hard to find a gift better than flowers. Not only do we ethically source our blooms and send them in 100% recyclable, compostable or reusable packaging, but we also pride ourselves on our varied collection that tailors to every taste and style. If you’re seeking a gift that reflects your sister’s personality, why not opt for a bouquet that echoes her character, or is steeped in sentimental meaning?

For the bold type
For vibrant personalities who brighten the room, a bouquet of blooms in uplifting hues is surely the way to go. Capture their spirit with sunshine yellow flowers, a fitting symbol of friendship, along with orange blooms that exude excitement and bright pink to represent love and joy.

For the truly elegant
If she embodies beauty and grace, send her flowers that match. Soft pastel hues are elegance in floral form, and even better if you choose a bloom that mirrors this. A bouquet of roses in sweet shades is truly timeless – just like her.

For love from afar
If you don’t live near one another, you may be wondering ‘how do I surprise my sister on her birthday’? Our letterbox flowers are the perfect birthday gift for a sister who lives far away. Packaged in a specially designed box that will fit through most standard letterboxes, this beautiful option can be easily delivered even if the recipient isn’t home. They also come unarranged, giving her the opportunity to put her flower arranging skills to the test.

What to write in a birthday card for your sister


Sending a thoughtful message along with your flowers will help to make her feel loved on her big day. Make it personal with a trip down memory lane, or remind her how important she is to you. Here are a few lines to get you started:

  • Happy birthday to the most wonderful sister. May your day be as amazing as you are.

  • Friends may come and go, but sisters are forever. Happy birthday!

  • Cheers to another year around the sun! I hope you have a great day.

  • Happy birthday to my best friend. I'm so lucky to have you in my life.

  • I'm proud to call you my sister. Happy birthday!

  • Wishing the world's best sister a very happy birthday.

  • "Flowers arrived on time and were of very good quality. My sister was delighted with them." – Anna, Arena Flowers customer

    Small gifts she’ll actually use


    The beauty of gift giving is finding something that the recipient wouldn’t buy themselves, and even better if it’s something they’ll actually use. For a thoughtful-yet-useful gift for a sister, why not send her a pamper kit for an evening of TLC? A beautiful candle with her favourite fragrance, a beauty set of deliciously-scented products and a bottle of fizz makes for the perfect night in. If she’s a foodie, send her a box of her favourite chocolates, or gift her a DIY meal or baking kit to put her cooking skills to the test.

    Cute, creative ideas to show you care


    For a truly sentimental and unique birthday gift for your sister, send her something steeped in meaning. A photo timeline or scrapbook of your best memories together, a playlist of your favourite songs growing up, or organise a game’s night featuring boardgames from your childhood.

    FAQs

    What should I get my sister for her birthday?
    Why not send her a bouquet of flowers? This thoughtful gift can be sent straight to her door, and will make her feel loved and appreciated on her special day. Flowers also make a great last-minute birthday gift for a sister, as you can enjoy next-day delivery until 9pm the day before.
    What flowers symbolise sisters?
    There are a few different flowers that symbolise sisters, sisterly love or the sentiment behind a sibling relationship. Asters are often associated with sisters thanks to a Cherokee legend, a story of two sisters who turned into flowers – one being a blue aster and the other a goldenrod. Symbolising love, affection and enduring bonds, asters also carry sentiments often associated with siblings. Yellow flowers, too, are steeped in positive meaning, many of which echo the love between sisters – yellow roses, for example, represent friendship and strong bonds, sunflowers are a symbol of happiness, and daffodils speak to affection. Light pink roses, meanwhile are a symbol of love and care, and make a thoughtful addition to birthday bouquet for a sister. If it’s dahlia season, a bouquet featuring the queen of the Autumn garden will carry messages of kindness, grace and beauty, all sentiments associated with sisterhood.
    Should you get your sister flowers on her birthday?
    We certainly think so! There’s nothing quite as lovely as receiving flowers, so why not lift your sister’s spirits on her special day?
    What is a simple yet thoughtful gift for my sister?
    Simply beautiful, flowers make for a thoughtful gift for any birthday. Whether sending a surprise letterbox selection or gifting them a luxury bouquet for a big day, nothing quite beats beautiful blooms.
