Looking back, we’ve been styling from an early age. As children, we were outdoorsy, climbing trees and making dens all day. Our mother would ring a bell that could be heard fields away to call us in at mealtimes. Our cottage had a tiered garden running down to the River Avon with sweet peas and an apple tunnel. Our business came about over a coffee in Oxford. I had taken up flower arranging as a pastime a few years earlier, with the aid of a few old Constance Spry books. An internship at Saipua, a floral design studio in Brooklyn, New York, opened my eyes to a way of treating flowers as an artistic medium outside of the traditional realm of floristry. When I came back, we decided the time was right for us to combine our skills. We chose the name Aesme because we love the way it looks and feels. Esme is a family name, as well as being the name of the protagonist in a couple of our favourite books - Rules of the Wild: A Novel of Africa by Francesca Marciano and For Esme - with Love & Squalor by JD Salinger. We added an ‘A:. to make it look graphically pleasing and modern, while the pronunciation remains feminine. Foraging is in our nature. A lot of the foliage, vines, grasses and branches that we use are foraged, especially the wild, wispy, sculptural elements that characterise our designs. But we also have a cutting garden in Hampshire which accommodates several varieties of tulips, ranunculi, anemones and narcissi, which are followed by old-fashioned garden roses, sweet peas, bearded irises, cosmos, foxgloves and Japanese anemones in the summer. We also buy from a variety of British growers and add seasonal blooms from Holland. We’re sisters but also very close friends. We’re very different, with contrasting characters and temperaments. In the beginning, this was frustrating because we both tried to do everything. Now, we play to each other’s strengths. I communicate with clients, source flowers and write the blog, while Jesse photographs, illustrates and prepares design boards. Our arrangements are an artistic collaboration. The juxtaposition of living and working in the city but sourcing and growing in the countryside is endlessly inspiring. The city provides us with the metropolitan buzz of commerce and an endless source of cultural inspiration, including museums, galleries and fashion. The countryside is somewhere we feel equally at home. It’s a place to breathe, put our hands in the earth and watch the seasons change. Our style of arranging is natural, loose and somewhat old-school. We have a great love of old-fashioned varieties of garden roses, nuanced colours and intricate vine elements. We lean towards different styles - Jesse loves Scandinavian design and mid-century furniture, while I’m into English country-house interiors and eclectic Bloomsbury prints:’ Aesme, 020 8741 3543, Photography/ Alun Callender
