You don't need to go far or spend money on a beautiful looking flower arrangement. Hydrangea's and hosta are such common summer foliage and lots of times they are overlooked as beautiful cut flower arrangements. These are pretty for your home or they are even elegant enough for a summer wedding centerpiece!
Simply cut long leaves of hosta and arrange them in the back of the arrangement. Fill in the front with shorter cut hydrangea's and the delicate flowers from the hosta. Experiment and arrange the flowers to your taste!
