Beautiful Foxtail Fern: Learn the Downside of Planting This Variety of Fern

My grandpa loved gardening. I learned much from him. To this day I enjoy puttering around in our garden, growing plants for beauty and food.

Foxtail fern

Foxtail fern

Foxtail fern is a beautiful plant that is hardy, evergreen, and perennial, making for a budget-friendly plant once purchased. Not only that, but it also spreads if its red berries find a patch of ground in which to sprout and grow.

Birds love the berries too, so whether you purposely plant them or let nature take its course, you are likely to end up with more of these fern plants once you have one or more in your landscaping.

Origin and Sun Tolerance

Foxtail ferns are soft to the touch and are related to the asparagus family of plants. This variety of greenery comes from South Africa and, in our Houston area, grows well in full sun and tolerates some shade. I have planted them in both situations with success in the past.

Foxtail seems an appropriate name given how those spiky stems with attached foliage simulate a fox's tail except in plant mode.

I purchased some at a nursery towards the end of the summer several years ago when the plant discount was 70%. Mixing them into our garden, I thought that they were striking specimen plants.

Foxtail Ferns May Choke Out Nearby Plants

Suddenly the nearby rose bushes were not fairing as well. A particular rose bush called Mother's Rose was given to me by a friend after my mother had died. It had been hardy and was able to be viewed from several windows in our home. It reminded me of the special friendship and love of my mother that my friend had also shared. It is a shame that I lost that particular rose bush.

What I found after digging out the dead rose bush had me consequently digging out our foxtail ferns also and giving them away. The foxtail fern forms tubers the size of a man's thumb, and they spread out far from the plant underground. It derives nutrition from the soil, but it chokes out other plants around it. Just be forewarned about this fact if you wish to use these ferns in your yards and gardens.

When giving my ferns away, I advised the person about not planting them near other plants unless they are deeply rooted like trees or planted against foundations such as homes or businesses nowhere near shallow-rooted plantings.

They would make an excellent specimen plant for container gardening. If kept in a container, the fern will need replanting every few years because of those tubers filling the soil area.

These are cold-hardy plants and rarely freeze back in our area. If we have an unusually cold winter and they do freeze, they rebound in the spring quickly. Just cut off any dead foliage above ground.

Characteristics and Growing Information

These perennial, light green-colored, evergreen plants thrive in planting zones 9–11 in the United States. Its official scientific name is Asparagus densiflorus 'Myersii'. As one might accurately guess from the title, it comes from the asparagus family, the Asparagaceae's official name.

In the spring, those foxtail-like fronds with the soft, needle-like leaves bear tiny white flowers that turn into red berries later in the year. Butterflies and bees like the flowers and birds consume the ornamental berries. I have read that the berries can be poisonous to cats and dogs, but we have personally never had a problem with that.

Propagation of the foxtail fern happens in two ways. One can plant the berries containing seeds directly into the ground. A much faster way is to take an existing plant, cut it with a sharp shovel or knife, bisect the fronds and tuberous taproots, and divide it that way.

The tubers below ground store water, so once the plants are established, they are drought tolerant. Well-draining soil is ideal. Water about once a week once the earth has had a chance to dry out at the top 3 inches. If grown in hard, compacted soil and receiving too much water, root rot can occur.

As you can see from the photo above, the older fronds often shed their leaves and become stick-like in appearance. Remove them by snapping them off or cutting them to keep the plant looking tidy and beautiful. Occasionally, when temperatures have gotten into the 20s, and if left unprotected, the fronds can be harmed. Generally, they rebound with new growth from the ground.

In northern climates, they can be kept as houseplants if given enough bright light and humidity.

Our foxtail ferns never had any pests. I have read that occasionally they can be harmed by scale insects or mealybugs.

Size and Spacing of These Plants

I would use them in landscaping again if I could start from scratch with a new garden knowing what I had learned the hard way. One needs to have space around them, as they can get up to about 1.5–2 feet in height and spread about 3 feet or so. See how the man in the video below has them spaced where they cannot harm other plants.

Hi Devika,

The foxtail fern is a beauty, but it is best to know about how the underground tubers can spread and choke out nearby plants. Thanks for your visit.

Devika Primić from Dubrovnik, Croatia on September 17, 2020:

Peggy I didn't know of the Foxfern until I read your hub. I like it and just like ferns. Interesting and informative about a different green plant. I learned to plant the Foxfern away from other plants too.

Peggy Woods (author) from Houston, Texas on August 29, 2020:

Hi Denise,

I learned the hard way that foxtail ferns could choke out other plants like roses. Your mother must have discovered that fact sooner than I did. Thanks for your comment. Stay safe!

Denise McGill from Fresno CA on August 28, 2020:

My mom had some years ago and I always wondered why they were suddenly missing from her garden. She had three of the most gorgeous Heart's Desire Roses in that bed and when the foxtail ferns left the roses really thrived. This explains is. Thanks for the info.

Blessings,

Denise

Hi Dale,

Thanks for sharing this article with your wife, or anyone else interested in growing the beautiful foxtail fern. Better to be forewarned about possible consequences ahead of time than to learn it firsthand by losing plants around it.

Dale Anderson from The High Seas on August 03, 2020:

Pwggy I have never been a gardener and, living ona boat now, I doubt that I ever will become one. But my wife is trying her hand at growing things so I'll put her on to your articles and hope that it helps her.

Peggy Woods (author) from Houston, Texas on July 12, 2020:

Hi Adrienne,

The old saying "knowledge is power" applies here. I am pleased that you learned something about this beautiful foxtail fern plant.

Adrienne Farricelli on July 11, 2020:

Thanks for sharing this important dark side regarding foxtail ferns. I didn't know until now that these ferns are related to asparagus, interesting!

Peggy Woods (author) from Houston, Texas on July 06, 2020:

Hi Rajan,

Planting these foxtail ferns in a container or near deep-rooted items such as trees is safe.

Rajan Singh Jolly from From Mumbai, presently in Jalandhar, INDIA. on July 06, 2020:

Never imagined something as beautiful as this fern can be as deadly as this. I believe planting in a container should possibly take care of that. Thanks for sharing.

Peggy Woods (author) from Houston, Texas on July 03, 2020:

Hi C E Clark,

Those tuberous roots can surely cause problems!

I hope you stay safe up there. This virus is gaining ground in so many places. Scary! We are doing our part in wearing masks and avoiding crowds.

C E Clark from North Texas on July 03, 2020:

Sounds like they could cause trouble with the neighbors too, if planted too close to a shared privacy fence and there were other plants on the other side that the neighbors valued. They are very attractive, though.

Reached 102º here yesterday afternoon for a while. :(

Hope all is well with you and that you are staying safe, which is getting harder and harder to do . . .

Posting this on AH & FB.

Peggy Woods (author) from Houston, Texas on September 14, 2018:

Hi Ethel,

The foxtail ferns are really pretty but can choke out other plants because of their bulbous and spreading roots. Happy to inform you and others of that possibility.

Ethel Smith from Kingston-Upon-Hull on September 13, 2018:

I do like the look of them Peggy but thanks for the warning. If I ever plant any it will be in a container away from other plants

Peggy Woods (author) from Houston, Texas on July 22, 2018:

Hi Patricia,

I am sure your daughter really appreciates all you are doing to help them. Moving is never fun. Hope that your treasured plants make the upcoming journey with you in good stead.

Patricia Scott from North Central Florida on July 22, 2018:

I am not sure if I told you but the house belongs to my daughter and son in law. They moved to another town several years ago to be closer to where my son in law works so I moved here to help them out. I am not thrilled about moving and have been packed almost entirely for several months. My plants were one of my first considerations as I have many I treasure. I had to dig them up and pot them and began that several months ago. Thankfully they are doing well and are ready for the move. NOW to just get on with it. Closing is set tentatively for August 15 so I am hoping there are no unexpected delays. Once again sending you hugs and blessings this morning ps

Peggy Woods (author) from Houston, Texas on July 21, 2018:

Hi Patricia,

Happy to be able to pass information like this along to others so that they know better where to plant these beautiful foxtail ferns. I could have ordered another rose bush to take the place of the one that was killed but did not do so. The memory of it and the person who sent it is enough. Hope that your move will be smooth and the reasons why you are doing it good reasons. Take care!

Patricia Scott from North Central Florida on July 21, 2018:

I just reread this and commented via my phone...not seeing it yet...I had forgotten what you said about it being invasive so am glad I saw this again. I am getting closer to moving so am looking at them more seriously now. Most of my plants are in pots now as I had to remove them from the ground to prepare for the transition. Angels once again headed your way ps

Patricia Scott from North Central Florida on July 21, 2018:

Thank you for this...I have always admired them but will relegate any I get to a container. So sorry you lost your special rose. Angels are in the way, Peggy

Peggy Woods (author) from Houston, Texas on November 30, 2017:

Hi Patricia,

Nice that you have your foxtail ferns in pots and can move them with you when your house sells. They are beautiful but need to be planted where they cannot harm other plants.

Saying some extra prayers for Heston Wayne.

Patricia Scott from North Central Florida on November 30, 2017:

Thank you for this information. I did not know this. I do not presently have any growing in my yard but have had them in pots. Whenever the house sells and I move I do plan to have some again. Knowing this information will help me as I select where to plant them.

Angels are once again on the way Peggy....need a few special ones for little man as his surgery caused some shaky moments last night. ps

Peggy Woods (author) from Houston, Texas on November 23, 2017:

Hi Roberta,

Had I known about the underground tubers and how they can choke out other nearby plants (those without deep roots) I would never have planted the foxtail ferns near that prized rose. Live and learn!

RTalloni on November 21, 2017:

I'm laughing at how often I've ignored friends warnings re invasive plants. This, however, is worse than invasive and I'll heed your warning. Moving towards container gardening any way. :)

Robert Sacchi on November 09, 2017:

That is amazing a plant that lasted a century. Dolores, your family seems to be blesse with green thumbs.

Peggy Woods (author) from Houston, Texas on November 09, 2017:

Hi Dolores,

Were I to grow the foxtail ferns again I would definitely keep them in pots.

That is something that you have a mint plant that has been kept in your family for over 100 years! Amazing!

The rock with the 2 holes is one in which Native Americans would have sharpened tools. My parents acquired it many decades ago and it has been kept in the family. I like it also.

Dolores Monet from East Coast, United States on November 09, 2017:

Hi Peggy - I am sorry that you lost a special rose. I have many plants that came from other people including a mint that has been grown in my family for over 100 years. I'd hate to see it go. Maybe the best place for a fox tail fern would be in a container. They sure are pretty. (I love that white rock with the 2 holes)

Peggy Woods (author) from Houston, Texas on October 19, 2017:

Hello lovetherain,

Yes, the foxtail fern is certainly pretty. Just be aware of those tuberous roots that can affect nearby plants.

lovetherain from Untited States on October 18, 2017:

Interesting and beautiful plant.

Peggy Woods (author) from Houston, Texas on May 04, 2017:

Hi Audrey,

The foxtail fern truly is lovely if planted in the right area so as not to crowd out other plants. Happy to know that you enjoyed learning about it.

Audrey Hunt from Idyllwild Ca. on May 03, 2017:

What a beautiful and unusual fern. It's good to know the downside of this plant. Thanks for a great introduction to the Foxtail Fern Peggy.

Robert Sacchi on July 14, 2016:

Thank you.

Peggy Woods (author) from Houston, Texas on July 14, 2016:

Hi Robert,

They would be fine in a flowerbed. In a pot every few years they would have to be replanted depending upon the size of the pot because those tubers would literally fill the pot and there would be little soil left after a while. The same with asparagus fern.

Robert Sacchi on July 13, 2016:

How would a flowerbed of these foxtail ferns look? Would they strangle each other?

Peggy Woods (author) from Houston, Texas on July 12, 2016:

Hi Robert,

The foxtail fern is truly lovely but should be planted where it cannot harm other plants. Thought I would share what happened to us so that others are aware.

Robert Sacchi on July 07, 2016:

Thank you, I appreciate the warning.

Peggy Woods (author) from Houston, Texas on May 02, 2016:

Hi Vellur,

I never told the friend that gave the rose bush to me what happened to it. Nice to warn others about the potential of losing precious plants if planted near these pretty foxtail ferns. I did not know better at the time. The foxtail ferns are beautiful if planted in the right place.

Nithya Venkat from Dubai on April 27, 2016:

Foxtail Ferns look beautiful but have a downside to them. Sad that you lost the rose bush given to you by your friend.

Peggy Woods (author) from Houston, Texas on March 08, 2016:

Greetings Seafarer Mama,

Happy to hear you liked learning about the foxtail ferns and how they spread underground with their tuberous roots. Appreciate your comment.

Peggy Woods (author) from Houston, Texas on March 07, 2016:

Hi FlourishAnyway,

As far as being "selfish little buggers" it is just the way the foxtail ferns were made and it surely makes for good survival.

Karen A Szklany from New England on March 07, 2016:

Great informative hub with beautiful pictures. Thanks for the warning about how they spread and procreate. :0)

FlourishAnyway from USA on March 06, 2016:

They're pretty but selfish little buggers.

Peggy Woods (author) from Houston, Texas on March 04, 2016:

Hi Frank,

Even if you were a botanist, there would probably be some plants of which you would still be unfamiliar since there are so many on our planet. Glad you enjoyed the article as well as the comments.

Frank Atanacio from Shelton on March 04, 2016:

Thank you so much for this educational insight, truth be told I didn't even know what a f oxtail fern was.. I'm not too familiar with ferns or plants.. I'm not a botanist.. so forgive my ignorance... the hub was good and I enjoyed the comments from the other hubbers too..:)

Peggy Woods (author) from Houston, Texas on March 03, 2016:

Hi BlossomSB,

Your mother obviously knew what she was doing with regard to containing these foxtail ferns. They are soft to the touch.

Peggy Woods (author) from Houston, Texas on March 03, 2016:

Hi Nell Rose,

Sometimes we do learn by experience when gardening and this was certainly the case with our foxtail ferns.

Bronwen Scott-Branagan from Victoria, Australia on March 03, 2016:

Thank you for the warning! Now I know why my mother used to grow them in hanging baskets, she must have known a thing or two. These ferns always looked such a pretty green and felt so soft to run our hands along.

Nell Rose from England on March 03, 2016:

What a great plant, but the part about your rose is sad. that's the trouble when we plant something new, its happened to me before, can't remember what plant it was, but all the others around it had to be moved, great hub!

Peggy Woods (author) from Houston, Texas on March 03, 2016:

Hi Martie,

That is interesting that this foxtail fern is called a cat's tail fern in Africa. It is because of those tuberous roots that that invaded the space where my special rose bush was planted that the rose bush died. Thought I would warn people of that fact. In a pot the roots eventually take up all the space. I agree that it needs repotting every so often for that reason.

Martie Coetser from South Africa on March 03, 2016:

In Afrikaans - directly translated - we call them cat tails. I keep mine in containers, but re-planting them from time to time is essential, as those invasive roots eventually take up all space. They are, of course, ideal in beds where they can thrive on their own.

Excellent hub!

Peggy Woods (author) from Houston, Texas on March 02, 2016:

Hello peachpurple,

Even if it is too hot to grow foxtail ferns in your area, I am sure you have plenty of other gorgeous plants. Thanks for reading and responding.

peachy from Home Sweet Home on March 02, 2016:

Those are beautiful plants that we can't find them here, weather too hot

Peggy Woods (author) from Houston, Texas on March 01, 2016:

Hi Alicia,

I agree with you that it is a very pretty plant. As long as it is contained or planted near deeper rooted things like trees...there is no problem. I am sorry that I lost that particular rose bush also.

Linda Crampton from British Columbia, Canada on March 01, 2016:

As I was reading your hub and looking at the photos I was thinking that the foxtail fern looked like a beautiful plant to put in a garden. Then I read that it was responsible for the loss of the rose bush planted in memory of your mother. I'm so sorry that you lost the bush and appreciate your warning about where to put the plant. It's certainly pretty.

Peggy Woods (author) from Houston, Texas on March 01, 2016:

Greetings JoanieMRuppel54,

So true! I never would have planted them near my rose bushes had I known what was happening underground.

Joanie Ruppel from Keller, Texas on March 01, 2016:

This is good to know. Sometimes we don't think about what is happening underneath the ground. Thank you!

Peggy Woods (author) from Houston, Texas on March 01, 2016:

Hi ChitrangadaSharan,

I am happy to pass this information on to others because the foxtail fern is indeed beautiful but one must be cautious on where to plant it. I have seen some planted in road divides where they are pretty and cannot infringe upon other plants.

Chitrangada Sharan from New Delhi, India on March 01, 2016:

The Foxtail Fern plant does look bright and beautiful!

Thanks for sharing the tips on how, when and where to plant it and the other precautions where not to plant it.

The description provided by you is very useful and helpful. Loved the pictures and the video as well.

Thanks for sharing!

Peggy Woods (author) from Houston, Texas on February 29, 2016:

Hello eugbug,

I am not familiar with bracken but if it is anything like foxtail ferns one must be careful where one plants it so as not to harm other nearby plants. I do think that the foxtail ferns are pretty and enjoyed them immensely right up until they killed that special rose bush of mine. Thanks for your comment.

Peggy Woods (author) from Houston, Texas on February 29, 2016:

Hi Au fait,

Thanks for sharing this information about the foxtail ferns. People need to know where best to plant these so as not to harm nearby plants.

The few leaves on the trees are falling like rain and trees are blossoming here also. The redbuds are so pretty. Our yard has lots of color with azaleas, roses, begonias, etc. in bloom. Hope all is well with you too.

Eugene Brennan from Ireland on February 29, 2016:

Interesting, the foxtail ferns look cute and cuddly but creepy at the same time, like giant green spiders or sea anemones! I grow bracken in the garden and it's a nice contrast to some of the other plants, however I read somewhere that the roots do something similar, spreading and choking nearby plants.

C E Clark from North Texas on February 29, 2016:

Good information to know. Glad you have shared it. They do look so pretty! Now is when so many people are sprucing their yards up and adding new plants, etc. Sharing this with followers.

Finally a 'normal' Texas winter and it's looking like we may have one of those nice long springs. Spring is the best season in Texas. Its so pretty once everything starts to blossom and the weather is usually moderate. Noted the trees are starting to blossom up here.

Hope all is well with you. Take care . . .
