Tom Karwin, On Gardening | Landscape Design: Plant Selection

Today's column continues our garden design series with a focus on plant selection.

Gardening can be fruitful on cold, rainy days as gardeners let patient plants grow roots and prepare for new growth in the spring. A unique motivation for this process may come to mind now as one of your New Year's resolutions.

The decision to grow a garden may be motivated by a move to a new garden, a decision to improve an unsatisfactory landscape, or a search for new ideas. The motivation may be the desire to create a year-round garden. With that in mind, today's photos are a selection of plants that look attractive in winter.

Since gardens are constantly changing, landscaping is not a permanent maintenance, but a significant change to the landscape. In the previous parts of this series, we covered the basics of gardening and the basic concepts of landscaping and landscaping. These columns can be viewed online at the Sentinel Archive: tinyurl.com/53557vht.

As we plan to explore plant selection ideas, the mention of "community garden" in a recent issue of the Garden Conservancy newsletter (gardenconservancy.org/) prompted us to consider ideas for gardening purposes.

Volksgartens are mostly indoor gardens that differ from high-end gardens.

Luxury gardens are works of art characterized by high design and classical horticulture. As a rule, they require a group of highly skilled gardeners.

Indoor gardens can be well-designed and artistic, and most of all, they often provide unforgettable scenery and entertainment because of their ability to grow and their love of healthy plant growth.

Scientific studies describe three groups of gardens, which we briefly present below.

• Naturalistic gardens treat plants as biological entities and define a culturally controlled biological community or habitat.

• Functional gardens consider plants as cultural elements during indoor activities.

• In ornamental gardens, plants are seen as part of the landscape design, either as a house or as a place for formal human representations.

While your entire garden may fall neatly into one of these three groups, some parts of the garden can be described as natural, functional or decorative. There may also be some overlap.

This analysis supports the plant selection plan.

Our previous landscape column recommended specific types of plants to plant (or care for) in each area. These categories include ground cover, small shrubs, large shrubs, creepers, small and large trees. Add to these categories any perennials, perennials, annuals, and other types of plants you might consider.

The gardening process boils down to choosing specific plants for each category and in your plan.

As with other stages of gardening, the choice of plants is linked to the design of the landscape. Whatever plant you choose should do well when placed in a specific position in the structure at maturity. In addition, each selected plant must be similar to its neighbors in terms of leaves, color and shape.

Some landscape designs favor contrasting foliage, flowers and shapes in the flower bed, while other designs may emphasize some of these features, especially flower colors.

Another intersection of landscape design and plant selection occurs in garden landscaping (mentioned earlier). For example, a nature garden can follow the theme of native California plants to help with plant selection. As another example, the appearance of an ornamental garden can be based on the color of the flowers or the combination of flowers; Native habitats such as Mexico, Asia, South Africa or Australia; Or preferred species such as a collection of roses. A functional garden can be dedicated to fruit trees or vegetables, or it can be a children's playground without plants.

Some gardeners eschew these many design issues in favor of spontaneous plant selection based on success with previously known plants, a chance encounter at a garden center or catalog, a gift from another gardener, or other inspiration.

And that's good, because the ultimate purpose of your garden is to bring happiness.

Plant selection should be a creative experience, structured or unstructured.

Enjoy your garden!
