Evergreens to me provide the most interest in the Winter garden, and are really the backbone or foundation on which a really nice year-round garden is built. They can be planted along with herbaceous perennials in the garden, to add height and act as focal points, or planted as specimens, spread out across your property. A mass planting of different sizes and kinds of evergreens can make a wonderful living fence, or border by themselves.
Evergreens come in basically four colors: Green, Blue-Green, a Grayish Green, and Golden/Chartreuse.
Evergreens seem to have four common Branching (not growth) Habits. They can be Upright pyramidal formed, with branches growing upward toward the sky (see illustration 1). The second growth habit is Horizontally Spreading, with branches growing straight out from the trunk, parallel to the ground (see illustration 2). The third is Weeping with branches growing / hanging downward toward the ground (see illustration 3). The fourth is Flat Ground Cover, where the branches of the evergreen grow a few inches, to a foot or so above the ground, but spread out like ground cover. This type of evergreen grows much wider than tall (see illustration 4).
All sizes and varieties of evergreens with shape descriptions such as ground cover, nest, mound, globe, pyramidal-cone shape, or column will possess one of the four branching habits.
Evergreen Needles and Leaves ..When it comes to evergreens, the needles and leaves come in a variety of Shapes, Textures, and Sizes. Illustration #5 shows a Hemlock, which has rows of short flat needles, that grow out from a center twig / branch. Illustration #6 is a Golden String / Thread Cypress. Its golden/Chartreuse leaves are long thin strands, with soft barbs on its scales.
Illustration #7 is a branch from a Pine. The pine can have 2 to 5 long needles per bundle, that grow off of its twigs / branches. Illustration 8 is a Moon-Glow Juniper. It has rough, pointed scale-like foliage that is gray-green. # 9 is the Blue Spruce. It is kind of bottle brush like, with needles growing out from all sides of its center twig / branch.
Illustration 10, the arborvitae has soft kind of fern-like, scale-like foliage. #11 the Yew has a similar needle shape to the Hemlock, growing flat out from the center twig / branch, but is bigger.
All of the evergreens just shown, and mentioned are from my garden, or surrounding land, that is in upstate New York, USA, zone 5-4. I really don’t want to go too much into the botanical part of the plants because they might not even grow in your area. Most Important, I want to get you to look more carefully at, and start noticing the different shapes, colors, and textures of evergreens.
When decorating your land with evergreens, especially if you are planting many together in a group, you want to place plants next to each other that have completely different kinds of needle / leaves, or extremely different sizes of needle / leaves. Really long needled Pines #7 would look fine paired with something like a Hemlock #5, that has a short needle. A bottle brush looking Spruce #9 would look just great next to a fern-like arborvitae #10. A Golden String / Thread Cypress #6 would be fine sited next to a Yew #11. You would not want to put a Cypress #6 next to a Juniper #8, or an arborvitae #10, because they all have too similar looking needles / leaves.
The only time you want things planted next to each other that are / look the same, is when you are mass planting many of the same variety of a single plant for a bold effect (ex. 3 pines in a row, followed by 2 arborvitae, then 4 hemlock).
Now let’s look at some photos showing some very interesting combinations of evergreens.
In photo-illustration 12, look at the two upright evergreens, that are wonderfully counterbalanced by the downward movement of the large weeping evergreen in the center. The Horizontal Spreading and Flat Grown Cover bushes, almost have limbs pointing toward the weeping specimen. This grouping of evergreens has all four branching habits in it. Look carefully at the different needle lengths, and leaf textures of all the different evergreens that make up this grouping.
The most important thing I want you to notice in photo-illustration 13 is how the weeping evergreen counterbalances all the upward thrusting and textures of the different varieties of evergreens. The weeping specimen pulls your eye downward to the ground. Without it, there would be too much of the same movement and shapes.
Photo-Illustration 14 shows, not only a wide variety of different evergreen needle / leaf shapes, but repetitive planting across the garden space. The mass planting of upright trees on the left, take a break, before resuming with a one more similar tree, that is behind the long needled pine mound, that is in the center of the picture. Also notice how two similar, but not exact, horizontal spreading spruce(?) flank the pine mound.
Photos-Illustrations 15 show different evergreens that are Flat Ground Cover, Horizontally Spreading, and Upright. Diversity of plant branching habits, plant colors, and plant textures all make for visual interest.
So there you have it, A Look at Evergreens in the Garden. I hope I got you thinking, opened your eyes to possibilities, and got your imagination churning, filling your mind with ideas and dreams that you could implement on your own land.
