Moderate-growing, clumping evergreen perennial to 2-4’ tall x 4-6’ wide. With a delicate and airy appearance, it’s easier to understand why this species was given the common name “Asparagus Fern”, though it’s not an actual fern at all. Rather it’s a durable, tuberous perennial exhibiting gracefully-arching, prickly green stems clad with tiny, deep-green, needle-like foliage. Newer foliage emerges bright-green to create an attractive contrast. While primarily favored for its foliage appearance, the bright-red berries that follow its inconspicuous, pinkish-white, summer flowers create additional appeal for this popular landscape favorite. These berries contain seeds that germinate easily in moist soil which should be considered when choosing a planting location as this species can be invasive. This tough and versatile plant is great for providing a texture contrast to broadleaf shrubs and perennials, and makes a superb hanging basket specimen. Tolerates a variety of soil types (provided they’re well-drained), and while this species can survive with little water once established, a more robust appearance is achieved with regular watering. Removing older foliage in early-spring will help promote a re-flush of lush new growth. Thrives in a sun to partial shade exposure. Too much shade will likely produce weaker, yellowish-colored foliage. It should be noted that the berries and stem sap of this species is toxic.
