We are are delighted when people upload pictures and request ID help; but, even without us, there are a number of fun and interesting ways to learn about the plants in your yard. From good-old-fashioned local field guides to the latest apps, the various methods will each have their own advantages and learning curves.
Most plant ID resources follow a logical path, using important key features of a plant to narrow down the selection to a few likely candidates. Knowing some descriptive traits and several of these key features will give you a good start towards the correct identification. A woody plant is one that develops bark on its older stems and branches, like trees and shrubs.

Some vines, such as grapes Vitispoison ivy Toxicodendron radicansor the Virginia creeper Parthenocissus quinquefolia shown above, will become woody as they age. Herbaceous plants, on the other hand, will maintain a green stem throughout their life cycle. These include plants like grasses, ferns, and wildflowers. A simple leaf is one single leaf, like this white oak leaf on the left.
The majority of plants are simple-leaved.
A compound leaf, like this Staghorn Sumac Rhus typhina centerhas multiple leaflets per leaf. Ash, Walnut, and Hickory are more examples of compound leaves. A double compound leaf, like the Honey Locust Gleditsia triacanthos on the right, will be double cut and have multiple leaflets per leaflet!
Along with their arrangement on a stem, leaves are described in terms of their shape and their edge. They can be round or oval, lanceolate long and pointed like a lanceovate egg shapedcordate heart shapedor wedge shaped.
Some have round tips, long-pointed tips or short-pointed tips, and may either have an uneven or an even base where the leaf blade meets the petiole, or leafstalk.

The edge of the leaf, or the margin, may be described as smooth entire or wavy. It may have lobes, or be toothed, or both.Madea - let them go
Toothed margins can be finely or coarsely-toothed and may be either single or double-toothed as well. Combinations of these traits are strong identifying features. For example, the elm Ulmus leaf in the top left has uneven bases and double-toothed margins, while the lanceolate shaped willow Salix leaf in the top right shows fine-toothed margins.
The sassafras species, in the lower left, is deeply lobed with smooth margins and the cordate shaped Eastern Cottonwood Populus deltoides leaf, lower right, has a coarse, wavy edge. Branching patterns will help you identify a plant as well.
Leaves and branches can emerge opposite from each other, at the same point on either side of a stem like the dogwood in the center, above.
Branches may also be alternate, emerging from independent points alternating left to right along the stem. The alder on the left is alternate-leaved. Another branching pattern is whorled, with three or more leaves emerging from the same point around the stem. Joe Pye weed Eutrochium purpureum above right is an excellent example of whorled branching.
In winter, when woody plants are leafless, you can still use the branches to classify. The short list of opposite-leaved species can be summarized in an easy-to-remember acronym: If your mystery plant has opposite leaves and branches, you can know it will most likely be one of these.
Of course, there are a couple of exceptions; it is nature after all. Image-recognition technology and crowdsourcing information have enabled the emergence of mobile apps for identifying plants. Many, like Leafsnap and GardenAnswersallow you to upload a photo of your mystery plant and computer software will try to match it with known images, offering a selection of possibilities from most-likely to less-likely.
Some apps, like Plantifieralso start with an uploaded photo, but rather than relying on an algorithm to match the plant to its likely species, the image is shared with other members of the community of users for help identifying the species.
While accuracy varies significantly based on who answers your request and the time frame for responses may be instant to never, there is an extensive collection of previously answered queries that you can search through. As the information is entered, the app begins to display possibilities.
The accuracy of these apps, however, can be limited by geographic region and by the selective database they draw from. Internet Search There are many online plant identification resources.
Some, like SimpleKeyprovide a system which guides the user through a series of questions about the unknown plant and provides suggestions as you answer. Identify that Plant is another website with extensive resources on plant identification including features to help you master the skill through training seminars, Facebook postsand email quizzes. Having a collection of several guides for different kinds of plants, like one for regional trees and shrubs, and another just for local wildflowers will narrow your possible selections and make identification easier.
Woody plants in winter can be identified by a number of consistent features that are not too difficult to observe. Even a talented artist could not turn these shrubs into nice sculpture. The Forsythia cube starts out looking promising, but this aggressive shrub puts out lateral branches very quickly.
The surfaces become dense. The top of the cube shades the interior and sides of the cube from the sun. The leaves fall from the twigs on the interior. The sides lose their leaves too. You end up with a green table held up by twigs. IF it flowers, the plant will have flowers only on the table A Forsythia sphere agains starts out looking promising, but again the branching is rapid and becomes dense on the surfaces.
To top of the dome quickly fills in. The interior loses leaves and becomes hollow. The sides below the equator of the sphere lose the leaves. You end up with a mushroom-like dome held up by twigs. Not a very successful sphere. And again, the flowering will only be on the dome So the advice for your spheres and cubes is to not use a sun-loving shrub like Forsythia. Stay with shade-loving species. Then, reconsider the shapes. If the sides can remain in the sun they have some chance of retaining the leaves.
So the shape needs to be widest at the bottom and should narrow toward the top of the shrub. So rather than a cube, consider a pyramid.
Rather than a sphere, consider instead a hemisphere. These shapes have at least some chance for success. It is also critical in home topiary to remember to thin surfaces so that some light penetrates the surface of the sculpture and and help the interior retain leaves to avoid hollow shapes. OK, so what do I do with my Forsythia? Rule of Thumb Pruning Natural pruning for shrubs is not done with hedge trimmers but with pruning shears.
This small hand tool makes individual stem cuts. The pruner also does not make his cuts at the surface of the shrub, again because pruning leads to branching. So the cuts are made closer to the ground to keep the branching dense from the base up rather than from the top down.
This also thins the canopy of the shrub so that light penetrates and the shrub remains well covered with leaves. For Forsythia, the Rule of Thumb pruning method provides a low-maintenance solution for keeping this aggressive shrub under control and flowering beautifully throughout the shrub each year.
Right after flowering, the pruner makes the annual pruning visit to the shrub.
stem | Definition of stem in English by Oxford Dictionaries
The pruner looks past the surface of the shrub, but looks at where the stems come up from the soil. Any stem that has achieved a diameter of the pruner's thumb is cut at the ground surface. That stem and all of its branches are removed.
That is all there is. Every shoot greater than thumb diameter is taken out each year. The Forsythia responds by sending up new shoots from the soil each year. These young canes bear flowers most profusely. The shrub looks like a small fountain going off, with young canes covered with yellow flowers each year.
The shrub is green inside and out, and the shrub stays relatively small. The gardener only has to prune once per year And the Forsythia has a shape that is uniquely its own. It does not look like a lilac, a rhododendron or a spiraea. Bonsai Perhaps the most extreme form of topiary is Bonsai. Again, this is an artform in which an artist picks a species and prunes it over many years to create a sculpture.
But the goal is not an animal or cartoon figure, rather it is to create what looks like a very large old tree in miniature. This tree should show signs of age, an accumulation of accident and environmental stress. It will be asymmetrical and windswept. Bonsai is achieved by extreme pruning of shoot and root. As needed to achieve the form of the canopy Again the cuts are made individually and with due consideration of where branches are desired.
Very fine pruning shears are the tool used. At least once per year, the tree is tipped out of its pot or pan and the lower third of the soil and root mass is cut away. This extreme pruning causes the dwarfing we observe as a result. A closely related artform is Penjing.
While Bonsai is Japanese, Penjing is Chinese. In Penjing, the older of the two artforms, the goal is focused more on producing a miniature landscape featuring usually more than one plant, and includes architectural details pagodas, footbridges, etc.
The artist had used maple as the specimen trees. The grove of miniature trees with black bark had an emerald green lawn of moss. It was autumn and the work had been properly kept outdoors in natural photoperiod and temperature swings. The leaves on the trees were suitably dwarfed by the pruning, but perfectly shaped maple palmate forms. At the time of my viewing the leaves were a mixture of green, orange, yellow, and red colors. It was just beautiful. Pruning for fruit trees Fruit or nut trees are often part of a home landscape.
Pruning these can be a bit confusing too. As is the case for the "rule of thumb" pruning, this is a once-per-year job. The form is not miniature forests or individual trees, but the form is critical. In winter, while the tree is dormant, the pruner visits the orchard and prunes to form.

The Central Leader form is used for nut trees. In this the main trunk is not cut back so that the apical bud continues to grow upward and the tree will achieve full height. The side branches are pruned to provide a wider base and narrower top for good sun coverage, and the canopy is thinned to allow good sun exposure and air movement for good flower and fruit development.
For fruit trees, the format depends on the varieties found in the orchard.
