Magnolia macrophylla #3 (Bigleaf Magnolia)

Bigleaf Magnolia is an ancient and interesting deciduous understory tree that is native to Southern Ohio and the Appalachian Mountains. With leaves reaching up to nearly three feet in length and up to a foot wide, it is very easy to identify with only one look-alike: our native Umbrella Magnolia. The massive leaves can be an overpowering feature in small residential landscapes, making this tree a better fit for large areas or a broad expanse of lawn as an intriguing specimen. A somewhat mature tree will bloom in June with creamy white flowers that can measure up to 14″ across and are stained purple toward the base of the inner petals. They have a pleasant fragrance, but often bloom so far off the ground that it is easy to miss.

Beetles are the primary pollinators of Magnolia spp. Pinkish-orange, cone-like fruits mature in the fall. The seeds are covered in a fleshy, high fat exterior that provides food for many small mammals and birds, especially those seeking high-energy food sources for southern migration. The foliage of Magnolia spp. hosts at least 21 species* of Lepidoptera, including the Eastern Tiger Swallowtail butterfly.

Bigleaf Magnolias appreciate moist but well-draining and acidic soils in partial sun. A protected location out of strong winds and direct afternoon sun will help to preserve the leaves throughout the growing season. They turn a rusty yellow-brown color in fall before dropping their massive, papery leaves.
