The Bigleaf Magnolia: A Rare Gem of the Understory   

The bigleaf magnolia is a relatively rare tree, though it may be abundant in small, isolated locations. Visually striking, the tree looks out-of-place amid the understory of temperate forests, as its large leaves give it a distinctly “tropical” feel.

Bigleaf magnolias draw a lot of attention among homeowners and landscapers, but these trees rarely thrive in exposed locations – the leaves simply suffer too much damage.  

Bigleaf Magnolia Identification: Tips & Tricks

Theoretically, the bigleaf magnolia should be very easy to identify, as it has the largest leaves of any North American tree. But in practice, it can be difficult to distinguish between the merely large leaves of its close relatives (the only trees with which you are likely to confuse this species), and the truly gigantic leaves of the bigleaf magnolia.

However, the bigleaf magnolia leaves have two “lobes” at the base, causing it to look like a letter “B.” Meanwhile, the umbrella magnolia (Magnolia tripetala) – one of the most similar-looking species – has leaves that form a “V” at the base. Fraser magnolia (Magnolia fraseri) leaves also have lobes, but they’re rarely larger than 12 inches.
