Use Boston fern indoors as a houseplant or as a seasonal accent plant outside once all danger of frost is past. These plants are ideal in hanging baskets, in raised containers, or on plant stands, so their long fronds can provide a dramatic arching fountain of foliage. But they can also be grown in the ground as somewhat upright accents among low annuals such as impatiens or begonias, combined with shade-loving coleus, browallia, caladium and torenia, or as a tall tropical-looking ground cover. Or combine potted Boston fern and other containers with colorful flowering annuals on decks or patios.
