Floral arrangements can range from simple to exotic, but it is best to seek advice from professionals for unique bouquets that will touch the heart of a loved one Traditionally, Valentine's Day is the busiest day of the year for florists, and roses, especially red ones, are the most sought-after stems. But there is a growing trend for designed floral gifts, which are more personal than a production line bouquet. For a unique bouquet that will touch the heart of your loved one, enlist the help of a professional. Kelvin Tang, founder and director of The Mozz, said designing a bouquet was like painting. Choosing the right flowers and leaves to create the perfect balance between colour, texture and density is an art. Sometimes simple arrangements can surprise. One of The Mozz's designs uses only white peony and deep burgundy calla lily with no leaves or other flowers. The shapes of the two flowers complement each other and the black and white colour scheme creates an elegant arrangement. 'To give a floral gift is to deliver a message,' Mr Tang said. 'For example, if you want to express that you are passionately in love with a person you might want to send a 3D heart covered with red roses and with rattan around the heart. You can also mix flowers and compose a story on how you think each kind of flower represents a quality of the receiver. We sometimes help our customers to make stories.' Mr Tang said the scent of flowers was also an important element, but was often forgotten. He said smells affected peoples emotions in a delicate way. Different flowers had different smells. Some made people happy, some made them feel refreshed. The receiver's character is as important as the message. Miranda Ma, the florist at Flowers by Miranda, said it was important to understand the sender's needs, the receiver's character and the couple's personal love story. She said before deciding on the species, colour scheme and arrangement, the sender should know what the receiver liked and why they wanted to send flowers. 'I treat the people who place requests as friends, rather than customers,' said Ms Ma. 'I care about every project, I think from their perspective, understand why they are sending the gift and how they want to impress their receiver. I take time to discuss with them and insist that the senders be involved in the whole process.' A specially designed floral gift was more than flowers, Ms Ma said. The thought process behind it was what really counted. For the hundreds of floral gifts Ms Ma designed, every one was different, she said. Last year, one of her designs was for a man who wanted to propose. It was an arrangement with different colours of spray roses making the shape of a cake, which was put into a cake carrier. When the cake was delivered, the receiver was in a meeting. She thought it was a real cake and put it in the fridge. When she got back, she took out the 'cake' and was greatly surprised when she found it was flowers - with a diamond ring in the middle. The customer called Ms Ma to thank her and praise her for her thoughtfulness. 'It is a great joy to receive unique flower arrangements and the joy grows with the blossom of the flowers,' Ms Ma said. 'I am always amazed to see how flowers show a different kind of beauty every day.' For every order, Ms Ma picks the flowers from the wholesalers and picks the best for floral arrangements. Sindy Chow, director of Charlie's Floral Design, said the convenience of the design also counted. Knowing where the receiver was going to put the floral gift was a consideration on what arrangement to choose. 'For material girls the bigger the bouquet the better, of course. For people who like to parade with their flowers, you might not want a huge bunch because it is too inconvenient to carry. You might want a small and special bouquet, or flower basket. For people who are going to keep the flowers at the office or home, you can choose a floral arrangement in a box or in a stylish vase,' Ms Chow said. She also gives suggestions on how to make flowers last. If it is a bouquet, remove the packaging, cut the stem in a cross shape and put it in a vase. Avoid putting flowers near fruit, wind and sun. Change the water every day.
