ASPARAGUS SPRENGERI

Normally planted in the spring, the fast-growing asparagus fern has a lot of good qualities, but it comes with some important cautions. In warm, humid climates, asparagus ferns can spread rapidly when planted outdoors—to the point of serious invasiveness. Neither plant is a fern, but instead, they are warm-weather perennials closely related to the common edible garden asparagus.
