The Magnolias Of Philadelphia

When I was first learning about various trees of the continent back in my idealistic youth, I was blessed to come across a free copy of Audubon's Field Guide to North American Trees (Eastern Region).  This was a marvelous book full of fun things like maps, pictures, and even illustrations of trees in silhouette, with the evergreens being nice and full, and the deciduous trees shown in their bare winter glory.  Now and then, I came across a remarkable leafy tree... with leaves on it!  I knew about them before, of course, being a traveled veteran of Southern Florida, but what really impressed me was the fact that some of them could be found very north, namely the American Holly (Ilex Opaca) and above all else, the majestic Southern Magnolia (Magnolia Grandiflora).  In specific, the guide noted that the beauty is noted for hardiness "north to Philadelphia".

In gardening circles, people are lately growing fonder of the art of "zone pushing", which is to say that they, ahem, we, like to grow things far north of where they are considered hardy.  Gardeners in Detroit, Chicago, Toronto, and Cleveland (and associated friendly cities) have long since considered anything that retains leaves in the winter to be of high prestige and a reminder that life goes on during otherwise snowy and cold dark months between November and March.  Alright, so October and April...  Anyway, its a hard thing to take even a cold hardy palm or broadleaved evergreen and expect it to dance for you while the blizzard rages, at least this far inland.  Philadelphia, on the other hand, is perhaps in one of the perfect situations for attending to a variety of cultivation.

While it has far more in common with the ocean than the Appalachians, it has elements of both; pine species form extensive barrens in nearby rural areas in both Pennsylvania and New Jersey, as well as more mountain species like rhododendrons in surviving woodlands.  It's not too hot, it's not too cold, and due to an atmosphere of tolerance, it was the American city that got the most brains to boot.  Massachusetts was all about religious agenda/freedom, New York was all about commerce, Charleston and Williamsburg were all about slave-powered farming, but Philadelphia was about letting you pray how you wanted, letting you argue with people over politics, and, surprisingly, letting you talk about what academic subjects were currently in vogue.  Alexander Hamilton of the spice islands by way of New York tried to get finance to set up a crown here too, but ultimately the city is still best remembered as more of a home to the Benjamin Franklin type.  This is a city of books, trees, and people who still like to read newspapers on a park bench.

One such popular academic interest was plants.  Aristocrats in Europe went crazy over trying to acquire New World vegetation for their estates, especially in England.  Various botanists made quite the name for themselves detecting and acquiring such treasures, and Philadelphia's own John Bartram earned the respectable but low paying title of the "King's botanist".  While Charleston, under Michaux, served as a secondary port for the thriving plant and seed trade, the varieties of climate and plant life meeting here, as well as the royal connection, ensured that Philadelphia would remain the chief point of departure for the finest trees finding their way to the finest clients.  Unlike Charleston, however, Philadelphia grew up much more snug and dense, seemingly paved over, much to the distaste of the founders and succeeding generations of planners in the city who wanted everyone to have a growing space.  Thomas Jefferson disliked the environment, and like many other politicians, wanted to try to escape to greener pastures when possible, which usually meant taking a trip to Bartram's house (which I regret upon regret not stopping at).  There they talked about plants.  No, really.  Jefferson and Washington were plant geeks.

Philadelphia has since greened rather nicely, even if the concrete which has replaced the brick is still the dominant feature everywhere.  The riverbanks are lush, there are parks and green spaces never far away, and the city is home to the United States' first urban national wildlife refuge.  Out of all this, however, what caught my eye was, well, the magnolias.  My little guide book did not disappoint.  I can't remember where half of them were taken at, with the exception of the line of tall ones at Betsy Ross House.  They are not hard to find, though.  Just wander through the historic core and you will find quite a few, some very impressive in size.

Yeah, that's a Sugar Maple (Acer Saccharum) intruding on the top left.  Pretty cool seeing them together!

These last fellows were at the Betsy Ross House.

There is also a garden consisting almost entirely of imported magnolias which, while not the majestic Southern Magnolia, do put on quite the show in spring.  I ran into some volunteers at the garden who gave me the unofficial history of magnolias in the city, as well as the intent behind the creators of this garden.  They explained that Washington, plant geek, wanted to green up the city he had to spend so much time in as president.  He was particularly fond of magnolias, which the ladies and I deduced to probably be his proud Southern Magnolias, arboreal symbols of American robustness.  As a symbolic tree, Magnolia Grandiflora is much more associated with the deeper South and with Andrew Jackson, who planted them at the White House as they were his wife's favorite tree.  Nevertheless, Washington probably would have run into plenty of them in his boyhood tidewater stomping grounds, as the tree was already making quite the impression in the trans-Atlantic trade and was already being cultivated as an ornamental in the southern lowcountry.  He probably enjoyed seeing a tree as robust as this in remaining green even in colder winters, and as a horticulturalist probably thought about bringing them further north with him into his presidential exile from Mt. Vernon.  The creators of the garden, acting 150 years later, apparently did not have the same design in mind, which the volunteers and I grumbled about.  The Asiatic magnolias, they said, are nice, but they only flower in the spring, and, well, are not very American.  At the risk of sounding like an ecological imperialist, considering the intent of the design of the garden, I have to agree.

Still, it's a nice garden (with a fountain, which I did not take a picture of), a quiet space of reflection surrounded by quiet streets (Locust between 4th and 5th streets) and various quiet places of worship.  There are thirteen flowering trees and shrubs which represent the thirteen colonies, but most of them are imports, and ironically, two of the species are iconic of England!  I'm a proud subject of the Commonwealth myself, but the concept seemed rather nutty to me.  If I had to guess, I would think that the creators wanted to put on an incredible burst of spring and early summer color, and to be fair, the garden was set up long after the colonial era passion for natives had faded and the Victorian and Imperial passion for exotics had become the rage.  Remember what I said about zone-pushing?  That's something fairly new, the current emerging vogue.  People maybe just weren't planting southern trees here back in the day, just as they weren't planting palms in Vancouver or London until fairly recently.

The worm has since turned, and the National Park Service tends toward at least the homegrown and preferably native ecological restoration as much as possible (and to be fair, as much as they work here and are not too distantly native, Magnolia Grandiflora is native no further north than the central Chesapeake, if I am allowed to make such a bold statement).  In the garden we get to see shifting trends in horticulture presented as a history lesson about a history lesson.  I have to admit, regardless of my angst, I stopped and enjoyed the patch of green for a while.  Washington probably would have done the same.  Jefferson would have turned cross, purchased nearby land, and started over on a superior garden.  Bartram would have sold him the plants.  All of them probably would have been in awe of the many Southern Magnolias found through the rest of the city.  I have to admit, seeing them together with so many other trees, including my favorite Eastern White Pine (Pinus Strobus) gave the city a pretty interesting arboreal landscape.  You can do that in DC too, but then you have to pay for it with hot, muggy summers that do not get nearly as bad here.

What's the rest of that city treescape look like?  Come on by next post for a tour.
