Asparagus can be evergreen or deciduous perennials or subshrubs, sometimes climbing, with tuberous rootstock. Stems bear both inconspicuous scale-like leaves and larger, leaf-like phylloclades, with small white or pinkish flowers followed by red berries.
Asparagus Setaceus is a bushy tuberous perennial developing twining stems to 2.5m tall, with fine feathery bright green foliage, small white flowers and deep purple berries.
The fern may dry out to the point it appears dead; however, outdoor springtime temperatures generally revive them. Keep the plant well watered in all situations and re-pot every few years. Care of asparagus ferns indoors involves misting the arching stems to provide humidity to the plant.
