Inspiration for Grateful Dead's song, 'Sugar Magnolia,' remains a mystery

Earlier this month, Bob Weir, rhythm guitarist, singer, and founding member of the Grateful Dead and many of its offshoots and side projects, passed away. If that seems like an unusual way to begin a gardening column, bear with me. Bob was not quite as famous as bandmate Jerry Garcia, but he helped carry on the legacy of the band for 30 years after Jerry passed, and Bob wrote and sang nearly as many of the Grateful Dead’s songs as Jerry did. Perhaps the most well-known of Bob’s songs was ‘Sugar Magnolia,’ and to honor his legacy, that is the plant I will write about this week.

Except, it turns out that there’s no such thing. There’s many different types of magnolias, of course, and far be it for me to question Bob and co-writer Robert Hunter’s botanical knowledge, but good luck finding a horticulture reference of any kind that lists one by that name. The NC State Plant Toolbox (plants.ces.ncsu.edu), one of the finest online plant databases, lists nineteen species of Magnolia, and countless cultivars, but a search for Sugar Magnolia turns up zero results. So which one of those nineteen species might he have been talking about?

I started learning about plants as a teenager, right around the same time I started listening to the Grateful Dead and other classic rock bands of the ‘60s and ‘70s. The first magnolia I discovered was saucer magnolia, Magnolia soulangeana, a hybrid with multiple trunks that lands somewhere between large shrub and small tree. Saucer magnolia is known for it purplish-pink early spring flowers, which are highly susceptible to cold and frost. Once I realized there wasn’t a true sugar magnolia, I convinced myself that perhaps this was the one the song was about, for no particular reason other than ‘Saucer Magnolia’ wasn’t a catchy song title, so changing the name was an artistic decision.

Sweetbay magnolia, Magnolia virginiana, is a more likely possibility. Sugar is sweet, of course, and there is a mention in the lyrics of “sweet blossoms,” so this seems to make some sense. The sweetbay magnolia is a small to medium semi-evergreen tree, with white spring blossoms that are pleasantly fragrant and showy, but smaller and not as prolific as many other magnolias. It is native to the Eastern United States. The Grateful Dead were from California and while they’d eventually tour the world many times over, it seems unlikely that they’d write one of their most enduring songs about a niche species from the other side of the country like Sweetbay magnolia.

So maybe it’s the more popular and grandiose Magnolia grandiflora, often called Southern magnolia. These are abundant throughout the Southern United States, including Louisiana, which perhaps makes the lyric “She can dance a Cajun rhythm” relevant to this discussion. Everything about this species is more impressive. The leaves and flowers are substantially larger than the sweetbay, and the height and width can be nearly double, so it certainly could make an impression on even a casual observer. It is not, however, particularly sweet. Its flowers are fragrant but not nearly as much so as the sweetbay. The mystery continues.

The Grateful Dead were notorious pranksters, and Bob often spoke of his sixty years of playing in the band as being just a small part of what he hoped would be a 300-year-long musical legacy, so maybe botanical nerds like me will be spending the next 240 years trying to answer this silly question while listening to the music play. Fare thee well, Bob.
