Bigleaf Magnolia

Highlights

The bigleaf magnolia is a breathtaking beauty, boasting the largest leaves and flowers of any tree native to North America. In a yard, it looks like something tropical. Magnolias are beloved plants; many species have a long history of cultivation. In China, certain species of magnolias have been cultivated for centuries. In Europe, the magnolia became symbolic of the aristocracy. However, it was the North American specimens that gave these plants their name.

Is bigleaf magnolia right for my yard?

Plant it if…

• You have a big, open space. If you have no idea what to do with a boring patch of land, this plant can help you.
• You have fertile soil. Former farmland, lots of compost: these things will make your plant very happy.
• You have a sheltered spot in your garden. Already have other trees? Great! They can help protect these large leaves.
• You appreciate fragrant flowers. Magnolias are traditionally pollinated by beetles, so their flowers are strongly scented.
• You have acidic soil. The bigleaf magnolia can grow in more neutral soils, but it prefers acidic conditions.
• You like magnolias, but want something more rare and unique.

Skip it if…

• You live in an urban area. The bigleaf magnolia is highly sensitive to pollutants, which are all too abundant in the big city.
• The winters are long where you live. Magnolias in general are very sensitive to frost, and the bigleaf magnolia is no exception. Untimely frost can leave your beautiful flowers brown and droopy.
• Your yard is small. This magnolia needs room to grow, so you may want to try a more compact species. In that case, the umbrella magnolia (Magnolia tripetala) might be your friend: it has a shrub-like habit that is easier to fit in a tiny space.

If you’re worried about the cold…

Cucumber magnolias are better for cold winters

If you live in the Northeast or Midwest and want to plant a magnolia, consider a cucumber magnolia. It has a similar look, but can handle colder winters.

Why bigleaf magnolia matters

Given the sheer size of its leaves and flowers, we’re a little surprised this plant isn’t more well-known. If there was a record for biggest flowers of any tree in North America, the bigleaf magnolia would be a record holder. The flowers are 8–14 inches wide, about the size of your head. The leaves are also a sight to behold, measuring 3 feet long and 1 foot wide. It may not have the same cultural spotlight as the southern magnolia (Magnolia grandiflora), but its size makes it the hidden queen of the forest. Like a queen, it provides for its subjects. Butterflies and hummingbirds enjoy the nectar, while birds and small mammals snack on the seeds.

This is a rare plant

The bigleaf magnolia is quite rare, growing in lowland forests in the southeast United States. They are often found in ravines and valleys, resulting in a fairly scattered distribution. The IUCN Red List classifies it as least concern. However, it was last evaluated in 2007 and likely does not account for the separation of the bigleaf magnolia into different species. Both Ohio and Arkansas have labeled them as endangered.

Where bigleaf magnolia shines in your yard

• Naturalized areas: If you want something low maintenance, leave it in a natural spot with moist soil and lots of leaf litter.
• Shade tree: The large leaves of this plant can provide some cooling shade during the summer.
• Specimen tree: Plant this tree in your lawn somewhere it can dazzle with its giant flowers and leaves.
• Woodland gardens: This tree is already used to the part shade of a woodland canopy, so why not plant it in an area that will feel like home?
• Shade garden: Pair it with some shade-loving natives for a lovely shade garden.

Bigleaf magnolia cultivars

When it comes to cultivars, other magnolias tend to be more popular. For example, the saucer magnolia (Magnolia × soulangeana) has hundreds of cultivars. The long history of magnolia cultivation has also resulted in a variety of nonnative magnolias. However, there are a few cultivars that give the bigleaf magnolia some love:

• ‘Julian Hill’: It looks fairly similar to the straight species, but it is considered hardier.
• ‘Mississippi Clone’: It has slightly larger leaves, but the pure white flowers are the true draw of this cultivar.
• ‘Palmberg’: The flowers are larger than the straight species.
• ‘Purple Spotted’: This cultivar is distinct for its purple markings in the center of the flower.

Related species

The bigleaf magnolia is not the only magnolia species with impressive leaves. There used to be two varieties of the bigleaf magnolia that have since been reclassified as their own species. If that wasn’t confusing enough, there are also other species that can resemble it at first glance. Here are a few related magnolia species:

• Ashe magnolia (Magnolia ashei): Previously considered a subspecies or variety of the bigleaf magnolia. It’s shorter and more shrub-like than the bigleaf magnolia, with smaller leaves and flowers, and is native only to Florida.
• Cloudforest magnolia (Magnolia dealbata): Another former variety of the bigleaf magnolia, native to Mexico. The common name comes from the habitat they live in; a rare type of forest found in the mountains and perpetually shrouded in mist.
• Cucumber magnolia (Magnolia acuminata): A smaller-leaved, but taller magnolia species. It has the widest native range, stretching from Canada to the southeast United States. Some indigenous tribes used wood from this plant to make canoes.
• Umbrella magnolia (Magnolia tripetala): A shorter species of magnolia typically found beneath the thick forest canopies of the Appalachian Mountains. As a result, it is a true shade-lover.

How to grow bigleaf magnolia

Where to plant

Full sun or somewhere a little shady will do just fine. All you need is space for it to grow into its best self. The soil is what you’ll really need to worry about. The bigleaf magnolia doesn’t like extremes, so make sure the spot you plant it is moist, but not wet.

Spacing

Leave about 25 feet of space for this magnolia to grow. It is slow growing, so you don’t have to worry about it being overcrowded right away.

Watering

Water thoroughly while the roots are establishing, using a few gallons two to three times per week. After that, as long as the soil stays moist, you don’t have to worry.

When to plant

Deciduous magnolias, which drop their leaves in winter, are best planted when they are still dormant. This way, they can concentrate on growing out a strong root system. The Magnolia Society recommends planting in “late fall or winter in warmer climates and early spring in cold climates.” You can follow this advice when planting the bigleaf magnolia, taking extra care to water thoroughly if you’re planting in the spring.

What pairs well with bigleaf magnolia?

The large leaves of the bigleaf magnolia will cast shade on any plants it is paired with. Additionally, the fall leaf litter could be a challenge for smaller groundcovers. As such, the best companions for it are shade-loving perennials and shrubs.

Where can I buy bigleaf magnolia?

Most big-box garden centers don’t carry true natives, but bigleaf magnolia is easier to find than you might think. Your best bets are a native plant nursery near you, a native plant society sale, or a trusted online grower that ships to your region.

Potential challenges with bigleaf magnolia

Finding bigleaf magnolia

Given its rarity, the bigleaf magnolia can be difficult to find in nurseries. Steve Pettis from the NC Cooperative Extension wrote, “Whatever you do, protect natural plant populations by avoiding collecting plants in the wild. Collecting seed is ok. Bigleaf magnolia seeds should be stratified for 3 months at 35-45 degrees.”

If that sounds too complicated for you, don’t worry. There are a few online nurseries that sell the bigleaf magnolia, which are listed here:

• Monticello (Charlottesville, VA)
• Direct Native Plants (Middle River, MD)
• Sheffield’s Seeds (Locke, NY)
• Woodlanders (Aiken, SC)

Why are we including the states alongside the sellers? It’s a secret gardening tip that picking plants grown in your area gives you a leg-up when it comes to survival. Here’s why:

The leaves

While the leaves are a major draw of the bigleaf magnolia, they can also make landscaping with this plant a challenge. This is a plant that requires personal space, and the large leaves may seem like a hassle when they drop in the fall. According to the IFAS Extension, the leaves decompose more slowly.

Thankfully, this isn’t a problem without its solutions. If leaf litter worries you, you can cut up the leaves with a mower, or by hand, to help them decay more quickly.

Large leaves also risk wind damage

When planted out in the open, strong winds can cause the leaves of this plant to tear. This can make it look ragged and messy, as well as potentially harming the tree. To combat this, place it in an area that’s shielded from the wind. Other trees, as well as your house, can give it the shelter it needs.

Magnolias were once seen as a symbol of the aristocracy. European nobility brought in Chinese magnolias for their estates, and southern magnolias (Magnolia grandiflora) were planted at plantations in the South. However, they all passed over the queen of magnolias: the bigleaf magnolia. It has huge, fragrant flowers and sprawling fan-like leaves that provide for all the animals of the forest. If you’re looking for something unique and beautiful, then this plant might just be for you.
