Evergreen Magnolia Varieties
Magnolias are a diverse group of flowering trees and shrubs, with approximately 125 species. While many people associate magnolias with their large, showy flowers, not all magnolias are deciduous. In fact, there are several evergreen magnolia varieties that provide year-round greenery and beauty.
One of the most commonly grown evergreen magnolia species is Magnolia grandiflora. This majestic tree is native to the southeastern United States and can reach heights of up to 20 meters in its natural environment. However, in the UK, evergreen magnolias typically reach around 10 meters in height.
There are also smaller cultivars of Magnolia grandiflora that are popular for their compact growth habits. ‘Little Gem‘ is a dwarf variety that grows just over 30 feet tall, making it suitable for growing in containers or smaller gardens. ‘Kay Perris‘ is another smaller cultivar with orange-tinted leaves, adding a splash of color to the landscape. ‘Teddy Bear‘ is a compact cultivar with glossy cup-shaped leaves and fuzzy undersides, giving it a unique texture.
Fairy magnolias are another type of evergreen magnolia that is highly prized for its fragrant flowers. These magnolias, which include species such as Magnolia laevifolia and Magnolia figo, produce pink, white, or cream scented flowers that are a delight to the senses. Magnolia x alba, a species from Southeast Asia, is said to bring good luck and is also evergreen.
Growing And Caring For Evergreen Magnolias
Evergreen magnolias are highly adaptable and can thrive in warm to temperate regions. When choosing a location to plant evergreen magnolias, it is important to select a sunny and sheltered spot. Although they can tolerate some shade, they prefer full sun.
For optimal growth, evergreen magnolias require well-drained, slightly acidic soil. It is crucial to keep the soil moist but not waterlogged. During the initial growth stages, it is necessary to provide frequent and deep irrigation to establish the tree, particularly during hot and dry periods. Annual mulching with organic matter helps retain moisture and provides essential nutrients.
If you plan to plant evergreen magnolias in pots, select a pot size that is one to two sizes larger than the root ball. Ensure that the pot has adequate drainage holes and fill it with slightly ericaceous compost. Plant the magnolia at the same depth as it was in its previous container or nursery pot. Regular watering is vital to prevent the large leaves from drying out. Organic ericaceous compost is recommended for potted evergreen magnolias.
In terms of hardiness, evergreen magnolias can generally withstand temperatures down to -10 °C. However, in colder areas, they can be grown in pots and overwintered in an unheated greenhouse to protect against freezing temperatures.
Notable Characteristics Of Evergreen Magnolias
One of the most striking features of evergreen magnolias is their large, dark green leaves. The leaves can grow up to 20 centimeters long and have a fuzzy brown underside, adding texture to the tree’s overall appearance. These leaves remain on the tree throughout the year, providing greenery even in the winter months.
The flowers of evergreen magnolias are equally impressive. Magnolia grandiflora, for example, produces cream-colored flowers that can reach up to 25 centimeters in diameter. Despite their beauty, evergreen magnolias are relatively slow to flower. It can take up to 25 years for a young tree to produce its first flowers. However, if you opt for grafted rootstock, flowering can occur in as little as 5 years.
Magnolia doltsopa is another variety worth mentioning for its large scented white flowers. This particular species is highly valued for its winter interest, as it blooms during the colder months.
There are also cultivars with unique features. ‘Bubbles,’ for instance, is a compact variety with glossy green leaves and white flowers with blushed margins. ‘Scented Pearl,’ or Magnolia laevifolia, has a long spring bloom period and produces creamy ivory flowers.
Best Conditions For Growing Evergreen Magnolias
To ensure optimal growth and flowering, evergreen magnolias thrive in specific conditions. They prefer sunny and sheltered locations, although they can tolerate some shade. The soil should be well-drained and slightly acidic.
In terms of irrigation, evergreen magnolias require regular watering, especially during the early stages of growth and in hot and dry spells. It is important to keep the soil moist but not waterlogged. Mulching with organic matter annually can help retain moisture and provide nutrients to the tree.
While hardy down to -10 °C, evergreen magnolias can be grown in pots and overwintered in colder areas. When planting in pots, choose a size that allows for adequate root growth. Make sure the pot has proper drainage holes and use slightly ericaceous compost.
Safety Precautions When Handling Evergreen Magnolias
When handling evergreen magnolias, it is important to take certain safety precautions. While these trees are not toxic to humans, ingesting the bark, wood, or fruit can cause mild poisoning or irritate the mucous membranes. Therefore, it is advisable to avoid consuming any parts of the tree.
Additionally, evergreen magnolias can cause skin and eye irritation. It is recommended to wear gloves when handling the tree to protect the skin from potential irritation. If any contact with the eyes occurs, rinse thoroughly with water and seek medical advice if necessary.
When it comes to pets, evergreen magnolias are generally not considered toxic. However, smaller animals, such as cats and small dogs, may experience gastrointestinal issues if they consume parts of the tree. As a precaution, it is best to keep pets away from evergreen magnolias.
Tip: To ensure safety when handling evergreen magnolias:
- Avoid consuming any parts of the tree
- Wear gloves to protect the skin
- Rinse eyes thoroughly with water if there is any contact
- Keep pets, especially cats and small dogs, away from the tree
