Plants For Concrete Garden Urns
Adding a new concrete garden urn to your backyard garden is a great way to show your own personal style, and add art to your home at the same time. Concrete garden urns will insulate a plant’s roots against temperature extremes, including freezing temperatures in winter and heat in summer. Additionally, concrete garden urns will not rust the way that metal urns will. Selecting plants for a concrete urn is similar to picking species for any other planting location. Here are several good plants for concrete garden urns. Drought-tolerant perennials provide strong uprights in concrete urns. New Zealand flax (Phormium tenax), hardy in USDA zones 9 through 11, provides sword-shaped leaves in an array of colors — red, yellow, pink, green and bronze. Though the leaves are the main attraction, New Zealand flax also produces red summer flowers. Another strong, upright plant is Adam’s needle (Yucca filamentosa), an evergreen member of the agave family that grows between 4 and 8 feet tall. Hardy in USDA zones 5 through 10, Adam’s needle bears tall stalks of fragrant, white, bell-shaped flowers.
Many gardeners like to fill concrete garden urns with annuals, either in single varieties or combinations. In large urns, annuals can also be used to fill in around the bases of tall perennials or shrubs. For easy maintenance use species like creeping zinnia (Zinnia angustifolia), hardy in USDA zones 2 through 11; shade-tolerant bizzy lizzies (Impatiens walleriana), hardy in USDA zones 10 to 11; nasturtium (Tropaeolum ), also hardy in USDA zones 2 through 11; and miniature petunias (Calibrachoa), hardy in USDA zones 10 through 11.
