Lofty plants are logical additions to landscape design for a number of reasons. The right choices can add height and drama, taking a garden space from drab to fabulous in no time and are often relatively low-maintenance.
Practical applications like foundation protection and erosion control can also be managed with these generous-sized plantings. One of the most common uses, though, is to create privacy.

But, what if you don’t have the ground space to plant such tall flora? Keep reading to explore some tall outdoor potted plants for privacy that work beautifully.
Types of Fuss-Free Potted Privacy Plants
Gardens come in various shapes and sizes, in different hardiness zones and contain distinct soil types.
When choosing the best tall outdoor potted plants for privacy in your garden, these factors should be considered to substantially increase in their success rate.
Other factors should include:
- The preferred height of your potted privacy barrier
- Deciduous or evergreen foliage
- Foliage colour (green, chartreuse, red, purple, etc.)
- Flowering, fruiting or non
- The type of plant (tree, shrub or climbing vine)
Once you’ve established these preferences, you’ll want to familiarize yourself with the benefits of each plant type.
Potted Trees
The tall and conveniently compact tree options below are well-suited for containers, to keep prying eyes out, and can be placed in almost any sized garden or side yard.
Strategically placed ones will even protect you and your home from the glaring summer sun and inclement winter weather.
Potted Shrubs
Given their shorter stature, shrubs are great for defining outdoor “rooms”. They can also establish property boundaries to deter wanderers.
Container-recommended shrubs are available in a variety of colours, textures and growing habits. Just make sure their mature size is appropriate for the pot you have in mind.
Vining Plants
Viners and climbers offer increased versatility. Simply insert a sturdy trellis, twice as wide as each pot along your privacy line and they’ll weave a blooming wall in just a couple of years.

13 Varieties of Potted Privacy Plants
The following have proven low-maintenance and highly effective as privacy plants, while also adding color, contrast and form to your landscape.
Take note of their care requirements and recommended hardiness zones. Matching these to what your garden offers will help to narrow your list.
1) Arborvitae

Potted Privacy Plant Care
On our list of tall outdoor potted plants for privacy, we’ve seen that each one is unique and caters to your individual preferences for foliage colour, growth habits and flowering.
However, plants grown in pots have different needs than those grown in the ground.
Let’s take a look at some specifics:
- Watering requirements: Potted plants require more frequent watering as potting soil presents a lower moisture retention rate than ground soil.
- Position: Be aware of sunlight requirements. Bloomers, like clematis and Butterfly bush, require full sun. Others can tolerate partial shade, while a few, like Japanese Maples, actually prefer shade.
- Temperature and Humidity: These are the primary factors that define your hardiness zone and the plants that thrive within it. Matching your favourites to your specific zone is imperative.
- Potting soil: Most plants prefer a similar soil structure. A loose loam with balanced drainage and moisture retention features.
- Soil pH: Each plant type prefers a specific pH range in which it can effectively absorb nutrients.
- For example, Hydrangeas and Japanese Maples prefer a low pH (high acidity). Bamboo prefers a neutral pH and Arborvitae favour alkaline (low acidity) soil.
- Feeding: Flowering plants generally need more phosphorus and potassium for bud production and development vs evergreen and non-flowering shrubs that thrive with more nitrogen.
Frequently Asked Questions
What is the fastest-growing plant for privacy screens?
The fastest-growing plant on our list of tall outdoor potted plants for privacy
is Bamboo, which can reach full maturity in a single growing season. Arborvitae and ornamental grasses come in a close second, reaching maturity in 2 to 3 seasons.
Do outdoor pots need holes in the bottom?
Yes! You can not successfully grow any plant in pots without drainage holes in the bottom. The soil will become saturated and drown the roots of your plant, eventually killing it. Since some of these larger plants are an investment, drainage holes are critical features.
