What plants can be outside all year?
Evergreen flowering perennials will keep their green foliage all year, long after the blooming season is over. Many herbs are particularly known for being great practical flowering plants with evergreen foliage, such as lavender, rosemary, and salvia, among others. perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials.
