Blank spaces and easy care are great reasons to consider getting some potted trees, or plants pruned into tree forms. Once potted, the proper trees need only consistent water, fertilizer and occasional pruning to thrive in your desert garden.
Potted trees bring a vertical element to a patio corner or wall, creating a focal point at a spot in your landscape—or perhaps providing a screen to unsightly elements. They can also offer a background to pots with flowers—and possible shade. Finally, potted trees offer a sense of permanence in your garden, especially during our long summer months.
You will want to choose trees that stay small or are slow-growing. Many tree varieties do not grow to full size when their roots are constricted in a container. Most trees will do best in larger containers, of course.
Look for trees that are evergreen so they maintain their contribution to your landscape or patio all year long. Some trees bring additional benefits—seasonal blooms, berries or even fruit! In the low desert areas where winter temperatures rarely hit freezing, many trees that show frost damage in other warm climates will excel year-round.
If you live in an area that does experience colder winter temperatures, you can cover the plants or move containers to a protected area during freezes and near-freezes. Of course, you’ll want to use pots that fit on rollers or dollies.
Citrus trees best suited for pots
- Improved Meyer lemon
- Mexican lime
- Bearss lime
- Kumquats (my personal favorite is Meiwa)
- Dwarf Alberta spruce
- Fern pine
- Yew pine
- Canary Island date palm
- Mediterranean fan palm
- Phoenix roebelenii (below)
- Pygmy date palm
- Pindo palm
- Sago palm (actually a cycad; poisonous to some pets)
- Windmill palm
Landscape plants that will do well in pots
- Acacia (many varieties)
- Chaste tree (Vitex agnus-castus)
- Crepe myrtle
- Oleander (poisonous to many pets—and therefore critter-resistant)
- Pineapple guava
- Texas mountain laurel
- Aloe in tree form
- Elephant’s food
- Madagascar palm
- Pencil cactus (sap is toxic)
- Ponytail palms
- Spanish dagger (green and variegated)
I put this in quotes, because houseplants are really tropical plants that people grow inside when living in climates with a true winter. However, in low desert communities where winter temps rarely get below freezing, most plants can live-year round on a protected patio. If an unusually cold spell arises, the plants can be covered or brought inside.
- Aralia palm
Shrubs that have been formed to look and act like trees are called standards. Their lower branches are removed to form a trunk. If you want to try forming one on your own, look for a shrub with a single strong center stem.
- Mexican bird of paradise (Caesalpinia Mexicana)
- Purple potato bush
- Yellow bells
- Duranta family plants (like Tecoma stans; skyflower)
