Look closely: the exquisite flowers you see here not only appear fresh but are natural – yet will last at least a year without water. Just launched in Miami Beach by specialist rose florist Palatial Petals, Timeless Luxury Roses are perfectly formed blooms that are preserved in oils to maintain their beauty for at least 12 months, and up to three years. They are available in a wide range of colours – from classic reds, pinks and champagnes to extraordinary shades, including a searingly bright spring green, dark velvet green, royal blue and black.

If your taste leans towards formal arrangements, Timeless Luxury Roses score highly: because of their flexibility and texture, they are more versatile than fresh flowers and can be fashioned into incredible displays (such as the  XL Deluxe Rose Box) $999; other  XL Rose Boxes)at $499). For those who prefer a minimalist approach, a Mini Timeless Luxury Rose Box costs from $49. A fabulous, Heart Shape Rose Box with 40 roses is $399 – which, when the cost of just a dozen fresh, non-lasting roses in Miami is taken into account (about $100), is not as expensive as one might think. And what a way to show everlasting love.
