Choosing Plant Containers

When choosing a container for an indoor plant, consider both practical and aesthetic factors.

The challenge to successfully match a pot and a plant could arise in two ways: you want an exceptional pot for a fine plant, or you want a find plant for an exceptional pot. In either case, the objective is a prominent display and you want the pot and plant to complement each other.

If you have a large number of plants in containers, the individual specimens tend to be lost in the crowd, and the containers might all be the same.

Rather than taking an abstract view of such decisions, let’s examine a case study of finding the right pot for a particular plant.

This is not fictional scenario, but a real-life challenge to select the right pot for a particular plant.

The challenge originated when a friend persuaded me that a freshly planted wall in my home should have an Amazon Lily (Eucharis amazonica), from central and South America. The generic name combines two Greek words meaning “good, true” and “loveliness.” The plant has impressive features: glossy, dark green evergreen leaves; plentiful white, daffodil-like blossoms; sweet and spicy fragrance; and no serious problems from pests and diseases. Because it prefers indirect light, it’s well suited as a houseplant.

Here is an example of the Amazon Lily, from aJanuary 2011 article in the Shreveport Times.

The Amazon Lily will grow to 18-24 inches high and wide in maturity and can remain in its pot, root-bound and happy, for many years.

This suggests a pot just large enough to accommodate the root ball and provide stability for the plant, while not requiring much soil to fill the space.

In addition to its capacity, the height of the pot should be considered. While there are no firm rules for pot height, a good starting point would be one-third to one-half of the plant’s mature height. In this case, we should choose a pot that is nine or ten inches high.

Pots suitable for houseplants are available in various materials: terra cotta, glazed clay, plastic, metal, etc. Many favor terra cotta pots, which are are widely available and inexpensive. Their porosity allows oxygen to reach the roots of plants, but also allows the soil to dry out quickly. Other materials are better for retaining moisture.

Both glazed clay and plastic pots offer many options of color and decoration. My preference is for glazed clay because it has more weight to stabilize the plant. Plastics in any form have negative impacts on the environment.

Notice that we are not considering black plastic nursery cans for houseplants!

Color is another consideration for the choice of container. Here are some options.

  • Monochromatic scheme: Given the plant’s striking, ever-present leaves, one or more shades of green would be ok. A simple dark green would provide a visual match.
  • Analogous scheme: This approach uses colors that are side by side on a color wheel. Starting with green (to go with the leaves), other colors might be blue and yellow.
  • Contrast Scheme: Create vivid contrast with three colors that are far from each other on the color wheel, e.g., blue-green, red-violet and yellow-orange.
  • Complementary scheme: The most dynamic combination uses two colors that are opposites on the color wheel, e.g., green and red.

When displaying a plant, it is generally best for the plant rather than the container to be the focus on attention. A pot that deserves to be featured should not contain a plant!

My choice is narrowing down to a dark green glazed clay pot that is no more than ten inches high. There are many possible choices with those features.

Very quickly, I found a pot that meets this objective. That was a surprise, because I had been looking off and on for a couple weeks, without success. Soon, I’ll post a photo of that pot (but I’m off to a garden tour right now).
