When choosing a vase, the first thing to consider is the number of flowers in your bouquet, and therefore the number of stems.Crowding too many flowers into a narrow-necked vase will make it look cramped, while too few will make it look sparse. Likewise, keep in mind that large-headed flowers will take up a lot of space. Choosing the right bouquet for the right vase depends on several factors, including size, shape and foliage.Below, we'll look at the shapes of designer vases and the type of floral arrangements that best suit each one.Bottleneck vases: As their name suggests, narrow-necked vases, like a bottle's, are perfect for supporting stems and keeping flowers upright. They're especially suited to thin-stemmed flowers; it's best not to crowd too many in so it doesn't look overloaded. Often smaller, narrow-necked vases suit small tables, mantelpieces, shelves or windowsills. Bottleneck vases are perfect for lilies, magnolias, cherry blossoms, catkins and hydrangeas.Vases en pichet (ou carafe) : A pitcher vase gives your arrangement a raw, rustic and natural effect. Smaller flowers and abundant foliage give it a freshly picked look, and pitcher vases are also perfect for dried flowers. Jug-shaped vases are perfect for small flowers and plants.Vases cubiques : With their many angles, cube vases make an excellent alternative to rounded shapes and showcase imposing, bold and colorful flowers like hydrangeas. In general, the shorter cube vases are better suited to short-stemmed flowers. Cube vases are perfect for large-headed flowers, including hydrangeas, roses and succulents.Vases arrondis : Reminiscent of a fishbowl, rounded vases are perfectly suited to tight bouquets and heavy flowers. They also make excellent terrariums. Round vases are perfect for roses, peonies and hydrangeas.Decorative vases: Decorative vases can take pride of place throughout the home and come in a variety of sizes and shapes. They're often unique, striking and can be just as bold as the bouquet itself. Decorative vases will pair perfectly with your favorite flower, and both simple and adventurous arrangements suit them well.Flared vases: The flared vase is the quintessential vase shape, with a neck wider than the base, echoing the shape of the flowers it holds. It's an ideal vase for those unfamiliar with home flower arranging, as it suits most bouquets. Flared vases suit most flowers, but are particularly well suited to roses, tulips and lilies.Vases de centre de table : A centerpiece draws the attention of all the guests; so a vase must be up to the task and catch every eye. A vase should be large and bold, able to hold a sumptuous, memorable bouquet. Centerpiece vases suit almost any type of flower, foliage or even unique objects to really make a centerpiece stand out.Footed vases: A footed vase adds a touch of elegance and draws attention as the focal point of a floral arrangement. Generally similar to a flared vase but raised on a round base, they're tall and make a perfect centerpiece. Footed vases are perfect for sunflowers, delphiniums and lilies.
