Sharing some House & Garden floral inspiration!
Try splitting taller varieties of flower among complementary vessels, as with these three elegant vases of delphiniums. They stand out on their side table pedestal making a singular statement. Check out http://nicolettecamille.com/ for more ideas.
Even for those who aren't keen on house plants, the glossy, shapely leaves of the humble cheese plant can look wonderful in a vase against dark, jewel-like colours. Just cut some from the garden or wayside - fabulous and free!
Nowhere are the clean, simple lines of orchids more visually effective than when they are used as a palate cleanser against rich chinoiserie pattern, such as in this dining room by Paolo Moschino.
