15. Dwarf Umbrella Tree
The Schefflera arboricola plant comes in many varieties, with one of the best known being the Dwarf Umbrella Tree. This statement plant works very well in a large pot with lots of space, because of its height (4-5 feet) and spread, but looks spectacular, so perhaps this is best suited to an office environment. It soaks up formaldehyde, toluene, and benzene. Some varietals offer variegated leaves and are a popular subject for bonsai trees if you like a challenge.
This tree needs bright, indirect light – keep it out of direct sun as the leaves will burn. If it starts to look a bit weak and spindly and the leaves droop and go yellow, it’s not getting quite enough light. Variegated varieties need a bit lighter than the green ones. This tree is pretty drought resistant so water only when the soil is dry, or the leaves start to wilt. Preferably use slightly warm water. Remember this is a tropical plant so it likes a humid environment.
You will need to prune your Umbrella tree by cutting off overgrown or leggy bits – try to shape it a bit and shortly after the pruning your tree will look healthier and fuller. Fertilizing is not really necessary. Watch for spider mites and mealybugs and wash the plant with soap and water to get rid of them. Try to avoid chemicals if you can. These plants are poisonous if eaten – both to humans and animals. As the toxins affect the mucous membranes, it can cause a burning sensation, swelling, difficulty swallowing and sometimes breathing. Their larger cousins were a popular choice as outdoor trees in milder climes in the past, but are aggressive invaders, so don’t transplant yours into your garden.
Be warned that plants grown indoors are more susceptible to disease and parasites, so keep an eye out for anything that looks abnormal and seek help at your local nursery. A hardy indoor plant may mean an aggressive invading plant outside, so think before transplanting your potted plants into your garden. You will have noticed that the same simple steps are required to take care of most of the plants in this list, so you can now consider yourself an accomplished inside gardener
