Will perennials survive winter in pots?
Perennials and shrubs that are in your zone or one colder can be overwintered in an unheated garage, buried in the ground, or transplanted. Perennials and shrubs in containers will need water through the winter but should not be kept wet. Fortunately, most tender perennials can be stored indoors over the winter, a trait that allows us to grow them well outside typical hardiness zones. For successful overwintering, prepare plants for the transition indoors and select the storage method best suited to each individual plant.
Can perennials be planted indoors?
There are a number of perennials that can work well as houseplants, suitable for a range of light and space conditions. Also, many tender perennials (those that are not cold-hardy in most climates) can be moved indoors for the winter to keep them thriving. Generally, herbaceous perennials are the most suitable houseplants but there are also some woody perennials—small shrubs and even trees—that work well indoors.Other outdoor plants with the ability to grow indoors include species such as: sago palm, tropical hibiscus, mandevilla, cast iron plant, jasmine, asparagus fern, ti plant, bird of paradise, cordyline, and crown of thorns.
