Evergreens For Pots: Best Evergreen Plants For Containers

By: Liz Baessler

Looking outside at your barren or snow-covered garden in the dead of winter can be disheartening. Luckily, evergreens grow very well in containers and are cold hardy in most environments. The placement of a few evergreens in containers on your patio will look good all year and give you a much welcomed boost of winter color. Keep reading to learn more about container grown evergreens.

Care for Evergreen Container Plants

When a plant is grown in a container, its roots are essentially surrounded by air, meaning it’s more susceptible to temperature change than if it were in the ground. Because of this, you should only try to overwinter container grown evergreens that are hardy to winters considerably colder than what your area experiences.

If you live in a particularly cold region, you can increase your evergreen’s chances of survival by piling mulch up over the container, wrapping the container in bubble wrap, or planting in an overlarge container.

Evergreen death can result not just from cold but from extreme temperature fluctuations. Because of this, it’s a good idea to keep your evergreen in at least partial shade where it won’t be warmed by the sun only to be shocked by plunging night temperatures.

Keeping a potted evergreen watered in winter is a delicate balance. If you live in an area that experiences a hard frost, keep watering until the root ball is completely frozen. You’ll have to water again during any warm spells and as soon as the ground begins to thaw in the spring to keep your plants roots from drying out.

Equally important is the soil for your evergreen container plants. Suitable soil will not only provide appropriate nutrient and water needs but also keep the evergreen from blowing over in windy conditions.

Best Evergreen Plants for Containers

So which evergreen for pots are best suited for this year-round environment? Here are a few evergreens that are especially good at growing in containers and overwintering.

  • Boxwood – Boxwoods are hardy to USDA zone 5 and thrive in containers.
  • Yew – Hicks yew is hardy to zone 4 and can reach heights of 20-30 feet (6-9 m.). It grows slowly in containers though, so it’s a good option if you want to plant it permanently in the ground after a few years.
  • Juniper – Skyrocket juniper is also hardy to zone 4 and, while it can reach heights of 15 feet (4.5 m.), it never gets more than 2 feet (.5 m.) wide. Greenmound juniper is a traditional zone 4 hardy groundcover that can also be trained as a bonsai in a container.
  • Pine – The Bosnian pine is another zone 4 hardy tree that grows slowly and produces attractive blue/purple cones.

Add year-round color to your outdoor space or quickly change the look of an existing design by planting dwarf evergreen shrubs in containers. Container gardens offer flexibility and a chance to add drama to any outdoor space, even a small one. Evergreen shrubs grow in several forms, including round, mounding, pyramidal or upright. Choose plants that fit your design based on growth habit, type of foliage and foliage color.

Evergreen trees in pots

Conifers make a surprisingly good plant for a pot. They are structural and have some wonderful shapes and shades of leaves.

The pot constricts the root growth so they won’t turn into monsters.

This dwarf Pinus mugo (left) has been in this pot for two years. I feed it in the summer and water it, but it’s very easy care. However I have been warned that if I ever want to take it out of this pot, its roots will have grown into the curve and it will be difficult to get out without a major root prune or breaking the pot. A vase-shaped pot wouldn’t have that problem.

The plant on the left is Juniper (Juniperus communis) and arrived as a tiny plug plant three years ago. It has been entirely happy in a pot since then and has grown to this size.

For the past few years, the ever-changing display of pots outside the front door at Great Dixter has always included several conifers.

Amaranth (Amaranthus)

A tall amaranth, such as love lies bleeding (Amaranthus caudatus) or Joseph's coat (Amaranthus tricolor), can add color and drama to a container garden, reaching heights of around 2 to 4 feet. Choose a container with adequate drainage holes, as amaranth likes to be moist but not sit in water. These are annual plants, so you will either need to start seed early or buy plants every year. But the nice thing about annuals is they allow you to experiment and be creative.

  • USDA Growing Zones: 2 to 11
  • Color Varieties: Foliage of greens, reds, purples, and yellows
  • Sun Exposure: Full sun to part shade
  • Soil Needs: Average, moist, well-draining

Blue Star Creeper (Laurentia axillaris)

Laurentia forms a froth of finely cut foliage with dozens of lavender-blue, star-shaped flowers. It adapts to all kinds of growing conditions. Although it blooms repeatedly, you will get more flowers if you give it a shearing in mid-season. You can do this in stages so that you are never totally without flowers.

Caring for an Olive Tree Indoors

Olive trees are extremely hardy. They are one of the oldest cultivated trees, having been grown in the Mediterranean for at least 6,000 years. They tolerate poor soil and require very little water. In fact, overwatering is the biggest mistake to make when growing an olive tree.

In addition to the aesthetic value container-grown olive trees lends to any home décor, these trees are pet and child safe. Considered non-toxic, I need not worry about growing an olive tree inside my home. So many times, I’ve purchased a houseplant on impulse only to find it was extremely toxic.

While it’s not difficult keeping a poisonous plant out of reach of my dogs, cats pose a different problem. Their athletic prowess allows them to reach any heights and their proclivity to gnaw on plants makes anything remotely toxic too dangerous to grow. (I tossed my sago palm after I became weary of keeping it locked up in one of the bedrooms.)

It's time to talk containers and how you can make the focal point of your container gardens a permanent fixture.

One large plant such as an evergreen shrub or small tree will not only give your containers some much needed impact but also save you money – and a few backaches – in the long run. That’s because this plant will become an anchor that remains in place year round even as you change out smaller, companion plants around it seasonally.

And while deciduous plants, such as Japanese maples, no doubt make beautiful focal points, evergreens offer more lasting impact, regardless of the time of year. When choosing an anchor plant remember not to scrimp on the pot select the largest container you can find for giving root systems plenty of room to stretch. Also, note that in summer, the confined soil of a container retains much more heat than garden soil does, so the more space the better!

Here are a few anchor plants to consider, depending on your climate, sun exposure and container space:

Conifers: Japanese cedar, hinoki cypress, longleaf pines, thujas, arborvitae

Yuccas and agaves: Succulents have never been more popular and are extremely drought-tolerant (be careful not to combine them with annuals that require daily watering because that might make the soil too moist for the succulents).

Camellia and sasanquas: Their waxy green leaves aren't the only plus: they also flower from late fall until early spring.

Fatsia: This plant, with its large shiny leaves, lends a tropical look to containers, and the more you pinch off its lower leaves, the more it grows.

Euonymous: Its waxy green foliage makes for great texture. Consider the variegated variety 'Aureomarginatus'.

Grasses: Even if they are not evergreen in your area, the texture in winter can't be beat. Bamboos, especially the black ones, offer a dramatic accent as well.
