Faux flowers and branches have gotten good enough to fool the experts (are you reading this, Sarah?). A couple of years ago, I spotted some eerily lifelike olive branches at Pottery Barn and decided to take the plunge. Here are some sources for similar branches:
Above: A 33-inch synthetic Olive Branch stem is £29 from the Olive Tree.
Above: A dozen 21-inch-long polyester Olive Branches is $69.90 from Earth Flora.
Above: Crate & Barrel offers a lifelike-looking Potted Olive Tree with concrete container for $199.
