The tallest version of these is 45 inches (about 110 centimeters) high, an impressive presence even without plants. Id imagine these will look spectacular used to display a bunch of tall dry grasses or branches, outdoors or in. The planters, made by Phoenix, Arizona-based Kornegay Designs, are called the Quartz Series.
The company has no inventory, as each planter is made to order. Custom colors shown in the image are azurite, citrine, topaz and amethyst.
