Those lovely soft growing arms can extend several feet in a mature plant and eventually be suitable for a hanging basket or trellising.

Asparagus Fern Types:

There are three common types of Asparagus fern plant. The Asparagus sprengheri, Asparagus plumosus and the Foxtail asparagus Fern.

The plumosus is the one I own. It is also known as Asparagus setaceus and Protasparagus setaceus.

Asparagus ferns (like asparagus in your garden) produce berries that ripen and turn either red or black. The stalks create fernlike foliage called cladodes.

They are lovely and easy care in all three forms. Each would be a good addition to your home decor and plant collection.

Asparagus ferns plants can grow as potted table top plants, hanging plants or even trellised.

When is a fern a fern?

All ferns reproduce by spores. Asparagus fern plants have no spores. They reproduce by growing in clusters from their tuberous roots.

And when mature, the asparagus plants will also grow berries in the correct conditions. The berries drop and reseed a new plant.

That soft elegant lacy growth we think of as fern fronds are cladodes. But they are soft and look very much like a fern.

Asparagus fern plants are NOT ferns at all. But still quite fernlike and pretty.

Asparagus Fern Thorns:

I highly recommend a good set of garden gloves when working with these plants.

When the plants are young you will not see thorns. But as the Asparagus plant grows and matures the spines will appear. They grow and harden. And those stickers can also fall into your pot soil.

Asparagus Fern prickles
Asparagus Fern forms prickles and thorns at plant maturity. The plant sap is also noxious and can cause skin irrtation. Handle the stems with care. Gloves will help protect your hands when pruning or transplanting this plant.

Toxic Plant:

All forms of asparagus plant is TOXIC to cats and dogs. And Humans.

Asparagus ferns contain sapogenins. These are toxic to both dogs and cats.

The red or black berry fruits are mildly poisonous. Not lethal. However, eating the berries causes gastric upset resulting in vomiting and diarrhea in pets and people.

Also the sap of Asparagus ferns will cause skin irritations and some rashing. Wear gloves when working with these plants or near them in your garden. And when transplanting or pruning them indoors as well.
