The Merrill magnolia, also known as Magnolia x loebneri ‘Merrill’, is a beautiful and vigorous tree that can add a touch of elegance to any garden or landscape. One of the first things to consider when planting a Merrill magnolia is its size at maturity.
Unlike its parent, the star magnolia, which has a slow growth rate, Merrill magnolia is a relatively fast grower. It can reach a mature height of 20 to 30 feet, making it a perfect choice for those who want a medium-sized tree that provides a good amount of shade without overpowering the landscape. This puts the Merrill magnolia in between the heights of its parent, star magnolia (which grows up to 20 feet), and Kobus magnolia (which can reach up to 35 feet).
The Merrill magnolia has a rounded to broad crown, which means it has a nice full shape that adds visual interest to the landscape. Its broad crown also provides a good amount of shade, making it a popular choice for outdoor seating areas or as a focal point in a garden.
In my personal experience, I have seen Merrill magnolias reach heights of about 25 feet after about 10 to 15 years of growth. However, it’s important to note that growth rates can vary depending on factors such as soil conditions, climate, and care provided to the tree.
If you are considering planting a Merrill magnolia, it’s important to give it enough space to grow. Planting it too close to other trees or structures can restrict its growth and potentially lead to problems in the future. It’s recommended to plant Merrill magnolias at least 10 to 15 feet away from any other trees or structures to allow for proper growth and development.
The Merrill magnolia is a wonderful choice for those looking for a medium-sized tree with a full, rounded crown. Its growth rate is faster than its parent, the star magnolia, but not as tall as the Kobus magnolia. With proper care and enough space to grow, the Merrill magnolia can become a stunning focal point in any garden or landscape.
