At least eight florists provide the service here, delivering fresh floral arrangements weekly or monthly to customers' homes and offices for $60 to $150 a bouquet, including delivery charges.
For these florists, such subscriptions account for anywhere from 10 to 60 per cent of their business and this is a growing segment.
The composition of the bouquets is dictated by what flowers are in season, though several florists - such as Charlotte Puxley, Bloomeys and Fleuriste - do take customer's preferences into account.
Others allow clients to choose their bouquet style - modern, romantic or classic.
While customers sometimes request delicate flowers such as hydrangeas and peonies, florists say these do not do well in Singapore's tropical weather.
So, many florists prefer to fill subscriptions with hardier varieties, such as Dutch carnations, Kenyan roses and proteas mixed with sprays and fillers, for a longer-lasting bouquet.
Advance orders mean that florists can plan ahead, place orders for unique flowers and stock only what they know they will need, cutting down on wastage.
Briton Charlotte Puxley, who opened Charlotte Puxley Flowers in Tiong Bahru when she moved to Singapore three years ago, has offered subscriptions on an ad-hoc basis to private clients, but will launch a formal subscription programme next month.
She says floral subscriptions are popular now because they are part of the wave of online shopping.
"Subscriptions are much more convenient for the customer and a great way of ensuring we can provide the freshest and most unique flowers possible."
Beverly's Blooms in The Central in Clarke Quay, which started offering a subscription service 18 months ago, and The Floral Atelier in Tiong Bahru, which launched its service in July 2015, also accept pre-orders of bouquets for occasions such as birthdays, anniversaries and Valentine's Day.
The founder of The Floral Atelier, Ms Lelian Chew, says it launched its Forget Me Not service when it opened after she noticed customers, mostly husbands, coming into the store looking frantic because they had forgotten an important date.
The service allows subscribers to choose up to five dates a year on which floral arragements will automatically be sent to their loved ones. Prices of such subscriptions vary depending on the size of the bouquets and the number of dates selected.
Ms Chew declined to provide exact figures, but says subscriptions now account for almost half of the business.
Ms Sarah Ching, co-founder of Fleuriste, says that subscribers now account for 10 per cent of its annual revenue, up from 5 per cent last year.
She puts the growth down to a greater appreciation of how flowers can beautify a space, adding that Instagram accounts of interior stylists have fuelled demand.
"Customers often ask for arrangements in cool, calming colours such as pastels, blue, or white and green to enjoy at home," she says.
"Once they bring flowers into the home, customers realise how the arrangements can change the look and feel of a space by adding colour and visual interest."
American Marc Whedbee, 36, signed up for Beverly's Blooms' Set It & Forget It Package 11/2 years ago after the birth of his third child.
He spends about $200 on three bouquets to be delivered on three important dates - his wife's birthday, their anniversary and Thanksgiving - each year.
His wife knows about the package and does not think the flowers are any less special because of it.
"We have three kids and she understands how busy we are," he says. "It is something she looks forward to."
For Ms Merissa Lim, 30, who started her subscription with Fleuriste at Chinese New Year this year, the service allows for hassle-free gifting.
Ms Lim, who works in sales, has a subscription of four arrangements for $60 each, which can be delivered any time in a six-month period.
The customised bouquets are typically delivered to her home and she has been so pleased with the service that she now also sends the arrangements as gifts to family members and clients.
"I need not worry about the quality of the flowers. I get a large arrangement worth more than the $60 I pay," she says.
Personalised approach to bouquets
When Australian Min Yong, 35, started Beverly's Blooms 18 months ago, she knew subscriptions would be central to her business.
"I love the idea of bringing beauty, love and calm and ultimately creating happy environments in people's homes and businesses," says Ms Yong, who named the company after her five-year-old daughter.
Currently a monthly service with a minimum subscription of three months, Ms Yong plans to expand to include a weekly subscription option next year.
Bouquets start at $75 and can be customised. They are accompanied by a handwritten note if they are a gift.
Restaurant owner Erika Masiero, 39, who got to know about Beverly's Blooms through Instagram, has been a subscriber for more than a year and looks forward to her flowers every month.
Ms Yong knows Ms Masiero loves hydrangeas and the colour yellow and tries to incorporate this hue whenever possible.
"The flowers brighten up the house and they make me smile. My kids love to smell the flowers, too.
"She arranges the flowers in beautiful ways."
Ms Masiero has also called on Beverly's Blooms for floral arrangements when friends have lost family members or for special events.
Subscriptions account for 60 per cent of Ms Yong's business and have a 75 per cent renewal rate.
Her customers are evenly split between expatriates and Singaporeans, roughly half of whom are men who have purchased the subscriptions as a gift for their partners. The other half are men or women who want beautiful flowers for themselves or their homes.
"After having flowers in their home for half a year, people become used to seeing their beauty and feeling the positive effects on their moods, so they renew their subscriptions," Ms Yong says.
Her personalised approach is another incentive for customers to return.
The florist learns each client's preferences in colour, style and flowers and records the bouquets sent so there are no repetitions.
She also provides a Set It & Forget It service where customers can pre-book bouquets for special events and occasions.
It is a favourite not only of husbands and boyfriends, but also of women who use it to remember their good friends' birthdays, parents' anniversaries or important milestones.
Subscribers will be contacted about a week before the special day and given a few days to think of a note, which will be handwritten on a card and delivered with the flowers.
"I want to make sure the sense of love and appreciation is there, that the recipient feels good because time and effort have been put into the flowers," she says.
She has handwritten notes for customers in German, French and Chinese.
"The notes are just two sentences, but they can change everything."
With Every's subscription service offers weekly delivery of romantic seasonal arrangements for a monthly fee.
Every Monday, the bouquets arrive in jars, which are returned with every incoming bouquet. They come in two sizes: Baby Bloom jars for $260 a month, and larger Posey Bloom jars for $390 a month, including delivery.
