This genus brings together dozens of species of plants, some of which are used as vegetables since they produce an edible fruit, asparagus, others are instead cultivated as apartment or garden plants in milder climates; they come from Europe and Africa. The plants are made up of erect light green stems, very branched; asparagus do not have real leaves, but cladodes, thin green twigs. A. plumosus is a climbing species, with cladodes similar to the leaves of ferns. A. meyeri has foxtail branches; A. sprengeri has a feathery and soft appearance, with thin and very branched cladodes. Some species produce small white flowers, followed by rounded dark-colored berries.
The Asparagus densiflorus plant prefers bright places, but away from direct sunlight. Almost all species fear the cold, preferring winter temperatures around 15 ° C; some species, on the other hand, resist the cold, but not at temperatures below zero.
Asparagus plants cultivated for ornamental purposes do not tolerate stale air; for this reason, it is advisable to ventilate the room frequently, without subjecting the plants to drafts of cold air.
