June Tree of the Month-Sweet bay magnolia

Native to the eastern half of the US, Magnolia virginiana, or sweet bay, does very well in St. Louis, sacrificing only a bit of height to live here compared to its east-coast siblings. It’s hard to find a specimen over 20′ in St. Louis, whereas, in the south or eastern regions of the US, it can reach 60′ or more.

Usually sold as a multi-stemmed tree, the bark is silvery-smooth and often shows a lot of ‘leg’ toward the base where leaves are few. And the leaves … wowzers! When the wind blows, those green glossy leaves show their silver linings underneath-beautiful. 

Sweet bays are considered ‘semi-evergreen.’ This confuses a lot of homeowners, especially those that don’t care for the evergreen Southern Magnolias with their coarse, thick leaves. Sweet bays retain most of their leaves throughout winter here, then in spring, produce new ones. 

Preferring full sun, they will tolerate part shade. A little protection from the west sun and winds are appreciated.

And I saved the best for last-the flowers. Sweet bays have dreamy, creamy white blossoms with a lemony fragrance that will stop you for a close-up sniff in late spring/early summer.

The seed pods that follow the flowers have bright red, showy seeds without being messy. 

Practically the perfect tree!

Why I love this plant;

-It’s native to the eastern US.

-Beautiful, fragrant white flowers

-Semi-evergreen leaves with silver undersides.

-Tolerates low or wet areas and heavy clay soil.

-Great multi-stemmed specimen tree.

-Super low-maintenance, with no major disease or pest problems.

What’s not so great? 

-The term ‘semi-evergreen’ is confusing to most home gardeners. Most leaves on sweet bays remain all winter, but new leaves will still emerge in spring. Sometimes this gives it a shaggy appearance until the fresh leaves mature. 

-If you are expecting a big bloom show like saucer magnolias provide in early spring, you will be disappointed. Sweet bay magnolias, like Southern magnolias, bloom later in the season, with fewer, but more fragrant flowers dotted throughout the canopy among the foliage.
