Perennials, shrubs, annuals, shade plants, and pollinator choices.
20 plant profiles with care + air-quality notes.
All recent plant mosaics are now divided into individual cards and added to the existing plant library. Each card includes care basics plus air-quality notes and the pollutants the plant is commonly cited for in indoor-air discussions.
Vegetables
Raised-bed and backyard vegetable basics for home growers.
Pet-Safe Houseplants
Common pet-conscious choices for cat and dog homes.
Air-quality note: These pollutant lists come from widely repeated indoor-houseplant references and chamber-style studies. In a real home, plants can help a room feel fresher, but ventilation, source control, and cleaning matter far more than any single plant.
