Trees add much to an outdoor garden, providing shade, scenery and oxygen. It's easy to see why anyone would want to bring them indoors. There are many trees that will thrive in a container, whether they are placed near an entryway to a house, on the porch or inside, where they can purify the air and bring in a fresh burst of greenery.
Aromatic and delicate, the Tea Olive (Osmanthus fragrans) is a large shrub or small tree native to Asia that can easily be grown as a container plant. Tea Olive is commonly grown for its creamy white blooms, which are intensely fragrant. The tree is sensitive to frosts and does well indoors where it can receive indirect sunlight. Tea Olive isn't picky about soil and will grow in sandy, infertile soils. Multiple containers can be placed together to create a sweet smelling hedge or screen.
False Monkey Puzzle Tree
Bunya-bunya (Araucaria bidwillii), also called false monkey puzzle tree, is a curiously named Evergreen native to Queensland in Australia. The bright green, cone-shaped tree grows well in containers either indoor or outdoor. The long-lived tree grows best in indirect, bright sunlight in soil that is well drained and moist. The plant produces edible seeds, and established Bunya-bunya trees are coveted for their timber in Australia.
Cabbage palm (Cordyline australis), also called the cabbage tree, is a small palm tree that boasts long, gray green leaves that cascade from a stout trunk. The plant makes an excellent natural indoor air purifier, removing benzene, formaldehyde and trichloroethylene from its surrounding environment. Cabbage palms thrive in moist, well-drained soil in bright, indirect sunlight. The palm should be fertilized every 2 weeks or so with water-soluble fertilizer during the growing season.
