Magnolia trees are not something that many people associate with Iowa. Most commonly, magnolia is associated with the Deep South, where they grow abundantly and perfume the air with their large, fragrant, tulip-like flowers.
While it’s true that we can’t grow all the varieties that thrive in the warmer climates of the South, there are actually many hardy varieties that will grow and thrive right here in the heartland. There are easily 40-50 different cultivars that are suited to our local climate here in central Iowa. The range of flower colors available is actually quite broad, too, from white to yellow to a whole spectrum of pinks.
Magnolias are an absolute show-stopper when they’re in full bloom in the spring. Often, the trees will be covered entirely in blossoms without a single leaf in sight, filling the air with their unique citrusy scent.
There are so many varieties of magnolia available that there’s one for almost every setting, climate, and desired bloom time. There are very tall and very short varieties and some that bloom as early as March or as late as June, in so many different colors. While most of them enjoy lots of sunlight, there are even a few magnolias that will do well in a shady spot.
Hardy Magnolias For Iowa
One of the common historical problems with magnolia in the midwest has been that they’d often get hit with a late spring frost during critical blooming periods, and their blossoms would not be hardy enough to withstand the freezing temperatures. Luckily, there’s been lots of research and development put into magnolia breeding. Over time, many later-blooming varieties have been bred to avoid those late spring frosts we often get.
Here are our top five hardy magnolia trees for your Iowa yard or garden.
Royal Star Magnolia is a fairly compact magnolia that can be pruned as a shrub or tree. It can grow up to a height of 20′ tall and up to 15′ wide. It features large-yet-dainty 6″ bright white double blooms that open to release their sweet fragrance in March. Royal Star performs best in a full to part sun location. This cultivar is a brilliant addition to moonlight or white-themed gardens.
Ann Magnolia is another compact variety, maxing out at 15′ tall and 12′ wide. It features gorgeous blossoms, with petals that are dark reddish-pink on the outside and pale pink to white on the inside. They open in April and get to be 4-6″ across. Ann magnolia likes full to part sun.
Butterflies Magnolia is considered one of the finest yellow magnolias. It is a medium-sized tree reaching up to 30′ tall to 15′ wide. The blooms of Butterflies magnolia are a beautiful canary yellow with a rich lemony fragrance. They open in April and are about 4-6″ across.
