One of the great ways to experience some of what one's own backyard has to offer is to brighten up said backyard with some local flora. This is known in landscaping and gardening circles as working with natives, that is to say flowers, herbaceous plants, shrubs, trees, cacti, and even grasses which are indigenous to the local area. Ever since I made American Voyages, I wanted to post about the joys and benefits of native gardening, but as I survey my own domain, I find that I happen to like not-so-local things in the yard as much as the next person. Instead of trying to create an oak-savanna or a beech-maple forest (both are found in remnants within the same few square miles around here), the latter of which might be frowned upon in our suburban fantasy world of golf-course trim lawns, I have some roses, azaleas, morning-glories, and heck, even a Bald Cypress growing. Last night I even found a hardy cultivar of the lovely evergreen Southern Magnolia (Magnolia Grandiflora) for sale, adapted for outdoor planting in lower Michigan. At this point, staring at the native elements in the lawn, a slight grimace came over my face as they reminded me how they were surrounded by exotics, and I realized my eco-hypocrisy.
My horticultural sins put to light then, what types of things can we plant, what do they qualify as, and what are their benefits and/or drawbacks?
Native Plants.
Native plants, as noted, are things that are indigenous to the local ecosystem. The term indigenous can be difficult to define, especially when we consider time parameters as one criterion. Something that seems to belong to a place these days might have only found their way there within a few thousand years or so, true. The global climate does change without human assistance over gradual periods of time, barring a natural disaster of planetary scale (such as a big old space rock hitting us). Technically speaking, under a vast scale, things like moose and humans are not indigenous to North America because they migrated here over the Bering Land Bridge during the last ice age. That said, we can pretty much claim that both Bullwinkle and our native peoples are, well, native, as both person and moose naturally found their way here, the moose no doubt being chased by a band of hunters across the dry Bering, neither knowing what they were getting into. Examples of native plants would be Live Oaks (Quercus Virginiana) in Florida or Black Spruce (Picea Mariana) in Ontario. Having a native plant in your landscape and garden is almost always a good thing, though this depends on the condition in which the plant is expected to grow. While a fern might be native to one's area, planting it in full sun requires it to get watered really frequently, which is an inefficient use of water. This said, here we have two sub-categories of native plants:
Native Plants in and out of Habitat.
The fern example stands out well, but flowers work even better. In the yard I have a single Purple Coneflower (Echinacea Purpurea, which has to be one of the most poetic scientific names out there), which is indeed native to Michigan and can be found in savannas and prairies in the state. Right beside it I have a Wild Columbine (Aquilegia Canadensis), which is native to Michigan and grows on the margins of forests and along similar clearings like river banks (and is also the flower on the blog header). In the foreground is a sprouting Rough Blazing-Star (Liatris Aspera), native to Michigan, and another prairie and savanna species. They are all planted beneath a charming Northern Pin Oak (trunk pictured, Quercus Ellipsoidalis), which just so happens to have an isolated native population here in Livingston and neighboring counties.

Now the coneflower is not extremely out of place here (though it does not have a record of being native to this exact county, but does right next door, which I dispute, which means I need to hunt some down). The field across from the subdivision actually is reverting to type into a savanna, and remnants can be found across the main roads adjacent to this field. The columbine is sort of out place, but as the savanna is surrounded by forests, not terribly so either. The blazing star is about at home as the coneflower, perhaps more so because they definitely occur in the area, and less so because they like a little bit moister of a setting than the local prairie/savanna. The oak, though planted by developers solely as a pretty landscape thing, is right at home. All of these being together naturally, however, is improbable. Sure, the yard could have once been one of the edges of the savanna grading into the forest and a columbine could be next to a coneflower as such, but... well in any event I suppose this is being overly technical. The point is, some of these are slightly out of habitat, and some might be in habitat, minus being grown in a lawn of non-native grass.
How is this good? Well, I have planted things that belong here, more or less. Insects get a chance to pollinate something that would otherwise not exist in a developed area, and a semblance of the native ecosystem is restored, albeit by introduction, native but introduced. The butterflies in the yard are plentiful and the whole scene is thus rather idyllic. How is this bad? Well, it happens to be a bit fake, but nature will not complain even if a botanical purist might. On that note, it would be a bit improper if this were not a lawn but a prairie remnant trying to be rejuvenated. In any case, this is the best I can do at making a nice little reminder of what was here without getting a citation for growing a prairie instead of a lawn, which in my opinion is sad, but people like their lawns.
Anyway, in the same vein, another good example of an introduced native, the Eastern Redbud (Cercis Canadensis). I apologize for the poor lighting quality of the image, but I only recently learned about the magic of light control on cameras.

Redbuds are indeed native to southern Michigan and are often a very striking part of our moister forests. They are so lovely that they tend to get planted a whole heck of a lot. They serve as an excellent example of "good plants" we see in our landscapes that would not have been here without human intervention, at least not in quantity, but are not entirely foreign elements of the local area, just the particular ecosystem in which they have been introduced. This means they might not have popped up here by themselves, but they also blend rather well with the local environment. Many plants reproduce by seed, and often the seed is carried to new places by animals, animals which sometimes also create new ideal conditions for the plant to flourish (browsing, den and nest creation, etc.). You know what? A guy finding a nice iris in a nearby marsh then planting it in his garden is sort of doing the same thing, albeit for aesthetics rather than as a matter of survival.
So why all the fuss about what belongs and what does not? Find out in two days and four days for parts two and three of this rant, as well as tomorrow when I do a little Q and A.
