Low Light Plants for Growing in Containers
Place plants that adapt well to low light in east or north windows, foyers, stair landings — anywhere that receives little or no direct sun. But remember, if it’s too dark for you to read a book, it’s too dark for a plant to grow there. The following plants fall into this category:
Cast-iron plant (Aspidistra elatior): Dark green, elongated leaves grow vertically, reaching a height of up to 3 feet. Place this plant in an area with a cool to average temperature. Expect it to grow slowly. Let the soil dry out between waterings, and fertilize infrequently. The cast-iron plant is one of the easiest and most reliable houseplants.
Chinese evergreen (Aglaonema): Some Chinese evergreens have dark green leaves marked across with white (Maria); others have yellow-green leaves with darker splotches (Silver Queen). Both types grow into lush, leafy mounds. Height varies, so read plant labels. They thrive in average temperatures as long as they’re not exposed to cold drafts. Let the soil dry out between waterings. Cut back older canes to promote new growth from the base. Chinese evergreens are very easy to grow.
Dracaena: Many species are available, and most are slow-growing. The most familiar species include Madagascar dragon tree (D. marginata), with long, thin leaves coming out like a fountain; corn plant (D. massangeana), common in office buildings, with tall canes sprouting wide leaves at the top; and D. warneckii, a large, shrubby plant with green-and-white-striped leaves. Place these plants in an area with an average temperature and medium humidity. Let the soil dry out between waterings, and fertilize infrequently. Leaf tips and margins may turn brown and crispy if the plants are overwatered. Dracaenas are easy to grow.
Mother-in-law’s tongue (Sansevieria trifasciata): This has been a houseplant since Neanderthal times, which explains the politically incorrect name. Its familiar vertical blades grow slowly to 18 inches. These plants thrive in cool to hot temperatures. Fertilize infrequently. Mother-in-law’s tongue is very easy to grow.
Peace lily (Spathiphyllum): Here’s the ubiquitous mall plant, and for good reason — its dark, glossy foliage, on 1- to 4-foot plants, looks sharp without too much attention. Peace lilies occasionally sport white flowers. They can tolerate low humidity. Let the soil dry out slightly between waterings. If the soil dries too much, the plant will wilt dramatically; however, it will usually recover an hour or two after watering. Peace lilies are easy to grow.

Gardening Glossary
annuals
Plants that complete their entire life cycle within one growing season. The plant germinates from seed, grows and blooms, and then produces seed and dies.

Gardening Glossary
biennials
A plant that take two growing seasons to complete its life cycle. It germinates and grows leaves and stems in the first year; produces flowers and fruit (seed) in the second, and then dies.

Gardening Glossary
bolt
When a plant flowers or produces seed prematurely.

Gardening Glossary
cold frame
A wooden or concrete block box in which you can grow plants or hold dormant during the cold winter months.

Gardening Glossary
cole crops
A family of vegetables, including broccoli, cabbage, cauliflower, kale, and Brussels sprouts. They thrive in cooler weather.

Gardening Glossary
complete fertilizer

Gardening Glossary
deadheading
The practice of pinching or cutting off spent flowers

Gardening Glossary
evaporative-pad humidifier
A humidifier in which fans blow across a moisture-laden pad that sits in a reservoir of water.

Gardening Glossary
harden off
The process of acclimating plants grown indoors gradually to the brighter light and cooler temperatures of the outside world.

Gardening Glossary
hardiness
The ability of a plant to survive is called its hardiness.

Gardening Glossary
humus
A stable end product of organic-matter decomposition that's believed to increase microbial activity in soil, improve soil structure, and enhance the root development of plants.

Gardening Glossary
Bacillus thuringiensis Bt
An effective bacteria that attacks only the larvae of caterpillar family insects. It is safe to other insects, animals, and humans.

Gardening Glossary
macronutrients
Mineral nutrients that plants need in the largest quantities: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.

Gardening Glossary
mulch
Organic or inorganic material placed over the surface of soil, usually directly over the root zone of growing plants. Used to conserve moisture, kill weed seedlings, modify soil temperature, provide attractive covering to garden beds.

Gardening Glossary
organic matter
Once-living stuff like compost, sawdust, animal manure, ground bark, grass clippings, and leaf mold (composted tree leaves). Used to enrich soil and improve soil texture.

Gardening Glossary
perennials
Any plant with a life cycle of three or more years. Herbaceous (non-woody) perennials include flowering plants and herbs, mainly. Woody perennials include trees and shrubs. Longevity depends on the plant and growing conditions.

Gardening Glossary
pH
The measure of soil's acidity. Soil with low pH means it's too acidic; soil with high pH means it's alkaline. Most plants grow best in soil with a pH value between 6.5 and 7.2. Neutral soils measure 7.

Gardening Glossary
photosynthesis
The process through which plants take nutrients from the air and from the water in the soil to produce sugars that fuels the plant's growth.

Gardening Glossary
primary nutrients
Nitrogen, phosphorous, and potassium are the three nutrients plants need in the largest quantities.

Gardening Glossary
root crops
Plants with edible underground roots such as onions, carrots, beets, potatoes, turnips. Most root crops are cold-weather crops.

Gardening Glossary
self-blanching
A type of cauliflower with leaves that naturally curl over the head and exclude light. Requires cool temperatures for leaves to curl effectively.

Gardening Glossary
sets
Small onion bulbs, about 1/2-inch wide, that were started from seed the previous year. Grow onion sets with the pointy end up.

Gardening Glossary
side-dressing
The act of adding a small amount of fertilizer around or "on the side" of plants after they're growing.

Gardening Glossary
succession planting
Planting small, 2-to-4-foot patches of plants every two weeks throughout the growing season so that you can harvest a crop over an extended period of time.

Gardening Glossary
thinning
The act of cutting the least robust seedlings in your garden to give the healthier plants more room to grow.

Gardening Glossary
vining crops
Crops that grow on vines, such as cucumbers, melons, pumpkins, and winter squash. They usually require support (staking, trellising, etc.) to keep them off the ground.
