While you've got outdoor planting on the brain, it's a great time to tackle your indoor plants as well! Aside from the aesthetics of indoor plants, they also provide many amazing health benefits.

Indoor Plants & Air Pollution

In the 1980's, NASA did a study on plants that reduce indoor air pollution. (Who better to understand the needs of an enclosed space?) Plants are miraculous things. Their leaves and roots, along with their soil and microorganisms, have the ability to remove toxic gasses from the air and convert them to new plant tissue. Furniture, household cleaners, building materials, and even new clothes can off-gas for months or years. Houseplants can remove carcinogenic gasses, such as benzene and formaldehyde, improving your indoor air quality (IAQ), and boosting their own growth. Plants also convert carbon dioxide to oxygen for you to breathe in and exhale again as carbon dioxide. This cycle is necessary for good health as well. As a plant’s leaves transpire and the moisture in the potting soil evaporates, humidity is added to the air. Being hydrated is good for colds, coughs, and sore throats. The recommendation is one plant per 100 square feet of space. A few of the plants NASA tested are:

• Gerbera Daisy (with the added benefit of beautiful flowers!)
• Golden Pothos
• English Ivy
• Peace Lily
• Several varieties of Dracaena

See the study for more information and the full list of plants.

Culinary and Medicinal Gardens

Think beyond traditional houseplants! Your interior gardens can also provide food and medicine. Many vegetables and herbs do well near a sunny window or under lights on shelving. You don’t need a greenhouse or a yard - you can even garden if you live on the 23^rd floor. Container gardening has gotten so popular that nurseries now offer dwarf varieties of our most loved plants. You can successfully grow citrus, tomatoes, and eggplant inside.

Other suitable indoor veggies:

• Radishes
• Salad turnips
• Lettuce
• Greens – kale, chard, spinach, mustards, etc
• Microgreens
• Bush beans
• Carrots

Herbs are a must-have in the kitchen! They don’t take up much space and will grow on a windowsill or under lights. Many herbs have medicinal qualities in addition to flavoring your food.

A few easy and essential culinary herbs are:

• Basil
• Chives
• Oregano­
• Rosemary
• Scallions
• Cilantro
• Parsley
• Bay leaf

Indoor Plants with medicinal properties:

• Ginger
• Garlic
• Thyme
• Peppermint
• Sage
• Lavender
• Lemon Balm
• Aloe (not an herb, but great medicine!)
