Iowa Native Plants
A plant is considered native if it has occurred naturally in a particular region or ecosystem without human introduction. There are many benefits in growing native plants. First, these plants are better adapted to soils, moisture and weather than exotic plants that evolved in other parts of the world. They need less fertilizers, pesticides or use less water. Second, they are unlikely to escape and become invasive, destroying natural habitat. Third, they support wildlife, providing shelter and food for native birds and insects, while exotic plants do not.
Noted for its lovely fall color, Acer rubrum (Red Maple) is a relatively fast-growing deciduous tree of pyramidal habit when young, becoming rounded to oval at maturity. In early spring, tiny red flowers, borne in erect clusters, appear before the leaves and are followed by red fruit. Emerging red tinged in spring, the leaves change to dark green with whitish undersides and often develop dazzling yellows and red in the fall. This Red Maple also provides some winter interest, with its attractive, smooth gray bark, often ridged and furrowed with age.
Noted for its spectacular fall color, Acer saccharum (Sugar Maple) is a large, deciduous tree with a straight trunk, wide-spreading branches and a dense, oval to rounded crown. Its foliage of five-lobed leaves, 3-6 in. (7-15 cm) ranges from medium to dark green in summer, and changes to a brilliant palette of yellows, oranges, and reds in the fall.
Striking all summer long, award-winning Actaea racemosa (Black Cohosh) is a beautiful perennial with deep green, finely divided foliage, enhanced by gracefully arching wands of fragrant white flowers in late summer and fall. The blooms are packed in fluffy spikes, up to 2 ft. long (60 cm), which rise well above the foliage, and mature into attractive seed pods.
Perfect for shade gardens, Actaea rubra (Red Baneberry) is herbaceous perennial forming bushy clumps of finely divided, bright green foliage, enhanced by clusters of small fluffy white flowers in late spring and early summer. Borne on conspicuous red stems which rise above the foliage, they give way to pea-sized glossy scarlet berries in summer.
Agastache foeniculum (Anise Hyssop) is an upright, clump-forming perennial with attractive spikes of small, tubular, lavender to purple flowers from early summer to early fall. Adding lovely vertical lines to the landscape, they are attractive to bees, hummingbirds, butterflies and beneficial insects.
Allium stellatum (Prairie Onion) is a bulbous perennial forming a very compact clump of flat, slender, grass-like green leaves, 12 in. long (30 cm). In midsummer to early fall, profuse, rounded umbels, 3-4 in. across (7-10 cm), tightly packed with rose-pink to lavender flowers are borne atop leafless stems just above the foliage.
Early-flowering, Amelanchier arborea (Downy Serviceberry) is a large deciduous shrub or small tree of rounded habit boasting a profusion of 5-petaled, showy, slightly fragrant, white flowers in early to mid spring. Borne in drooping clusters, they appear before the leaves emerge.
Amelanchier laevis (Allegheny Serviceberry) is a large deciduous shrub or small multi-trunked tree of dense, fine-textured branching habit with purplish to bronze young leaves. In mid spring, abundant sprays of small, slightly fragrant, white flowers emerge as the leaves unfurl.
