PlantFiles: Giant Burro's Tail, Donkey's Tail
Sedum morganianum

I put my donkey tails in the north west window in Arkansas. It grew all the way to the floor It was hug between to windows at the top.I let it get very dry before watering it.I watered from the bottom. This plant was a silvery green.
I moved to Wyoming. I just bought another one but it was darker green and shiny with a touch of red .I wondering if it is the poison one.It had no information on it. I set this one on the top of my computer desk in the north window. It grew long quickly with not very many peas on it.I never had this problem with my other one in Ark.This planter has no water hole in the bottom of it.I think I'm going to have to put it in another pot with sand.
I'm going to search more about this. I love this plant.
I have been growing all kinds of plants all my life over 50 years.

I found a small pot containing three tiny tails at a local garden center almost a year ago.. it looked healthy and bug free but in need of a good home.. I re potted it into the edge of a dish holding other small baby succulents and has been doing well but as healthy as it looks sure does not seem to grow fast .. Sunday I found what I thought was the same plant at another garden center and grabbed both pots of them.. they were jam packed and I took all 30 some tails and put them in various pots in garden.. in comparison my newer ones loose their what I call " peas" way easy in comparison to my first which does not.. I am convinced I have two different breeds. My first ones have very slight different shape and a deeper shade of green. I have handled these little gems alot over the last 8 months and Never had any reaction at all.. I also have two cats whom believe everything I touch they must also.. they to have had no issue.. Perhaps some people have reactions where as some of us wont. Everyone's body is different. These tails have become my favorite eye candy plant and look forward to them reaching a few feet and will buy up any I see as long as they are healthy. I saved all the "peas" when I re-potted the two new plants for a few days (3 1/2) and just today scattered them in some sandy soil mix in a filtered sun lit part of my garden. I plan on giving them a light misting every 4 days or so. My goal is to create some of those gorgeous dread heads I seen here and on Pintrest. Overall..I have a personal plant rule.. I get it, I do my research and after my initial re-pot if it survives a month its a keeper..I think some plants respond better to some of us than others.. but a plant worth trying as it is quite unique and its potential to grow 3 to 4 feet is rewarding.

Live in Wyoming, so of course, my Burro Tail is inside (too much wind, etc.). I took cuttings from a friend's plant that looked very sad and put it in one of those double pots that are supposed to water from the bottom. I did that because the upper portion had a rounded edge which I thought would keep the plant from breaking. It's been 1 and 1/2 years now & it is 3 feet long and has blossomed! (My plant in S. Cal never did that!) It is located in a southern window (full sun), and I water it about once a week. (Maybe too often since whenever I touch it, leaves fall off-I never had that problem in S. Cal-although that one was out in a shaded patio area and probably was watered every 2 weeks). I have several cuttings in the classroom-it is not poisonous!

I'd like to upload a pic of the poisonous plant that this one is often confused with, but not sure how...so here's the link address...

Today is April 6, 2011 and I have been fighting a double eye infection since the fall of 2009 due to this plant. While pulling some donkeys tail out due to overgrowth, some of the sticky white discharge from the stem got onto my hands. I immediately washed my hands after I went inside, but evidently didn't get it all off. A little while later my eyes started to burn horribly, and as they burned and my eyes watered, the liquid that came from my eyes and ran down my face burned my face. After looking on the internet and seeing that this plant can be dangerous/toxic (but not poisonous?) I called poison control anyway, for the first time in my life. They told me to flush, flush, flush my eyes out with cool water. I did this for over an hour, and did manage to get one eye to stop burning. However, the other eye burned and was inflamed for a couple of days after that. My regret is that when poison control called back to check on me after flushing my eyes for that hour and advised me to go the emergency room, I did not go. Fast forward to a year and a half later and countless (and I mean countless) trips to the eye doctor and numerous prescriptions for everything from steroids to antibiotics and everything in between, my infection has not gone away and is in fact growing worse. My eyes (one is much worse than the other) are extremely inflamed and puffy, both in the upper and lower eyelids. They constantly drain yet feel dry. It is terrible! The doctor I am currently seeing says that they have never seen this type of infection this bad before. I don't know what to do at this point as it is starting to effect my vision. I just wanted to warn everyone that this plant can indeed be extremely dangerous. I have never posted a comment online before and joined this forum specifically to post this warning about this plant.

My daughter has a beautiful Donkey Tail that she transplanted yesterday and now is itching very badly, etc.
This plant should have stronger poison warnings and a remedy for the skin irritation posted!!

This is a great little plant, and fun to propogate. You can even start new plants from the little "peas" that come off the main vine. PLEASE BE AWARE this plant is NOT Euphorbia myrsinites, the invasive, poisonous nasty guy some of the other comments are refering to which is also sometimes called "Donkey Tail." You could probably eat this one (though I wouldn't recommend it). Fun plant and can do some really creative window-box decorating. Our first cutting came back from Hawaii with us (contrary to popular belief, you can bring plants back from Hawaii if you know the rules) in a ziplock bag and was planted within the week in semi-sandy soil in our greenhouse.

I have a rather large 20+ year old Donkey's tail, and recently it did something it has never done in it's lifetime. A long(aprox 12inches) stem topped with two large(3" diameter) green fuzzy petal-like leaves emerged from the center of the planter. A day later two, half inch long dark-pink tubular blossoms appeared in the center of the newly formed leaves.
I have searched everywhere on the web and found nothing about regarding these flowers.... It has never blossomed the way many photos I've seen, and I thought this was peculiar. Anyone out there have any info regarding this mysterious blossom?

This plant is not only highly toxic but it is also HIGHLY INVASIVE! If you are a supporter of native plants to the area that you live in, please do not plant this plant in your yard.

I just love this interesting plant and it's really a big conversation piece amongst friends. I use it a lot for planter heads and it gives the look of dreadlocks. I was sure surprised lately with some very pretty pink blooms. I give my head planters a haircut every so often and just poke the cuttings into a sandy-soil mix and they take off! In a year, I would say that mine have grown about 6 inches. I possibly have them in too much sun though, under an enclosed pool cage as they become a little yellow. I read about transplanting a 20 year old. I just don't know how I would do that as the plant is just so fragile and tends to break off easily. Good Luck!

My best friend had these before he deployed to Iraq, and I LOVED them, but was never able to get a cutting... I currently live in Sanford, NC. Does anyone know if they have these around this area?!?!?

I love this plant and I have a lovely specimen that I have been growing for more than 20 years. My problem is it needs repotting (it is quite large) and I wondered if anyone has any tips for doing this without damaging the plant too much.

"Donkey tail" is a common name given to two very different plants. I love this plant and am so sorry to see it get a bad reputation.

Euphorbia myrsinites (donkey tail or creeping splurge) is poisonous. Allergic reactions are not uncommon in Euphorbias, in general.

Sedum morganianum (donkey tail, burro's tail, lamb's tail) is a succulent and is safe. The pictures on this page are the harmless succulent. If you bought a donkey tail sedum and it looks like the pictures on this page, you are safe.

I JUST BOUGHT A SEDUM BURITTO PLANT FROM WALMART AND IT NEVER SAID IT WAS POSIONOUS. I AM SO GLAD THIS SITE TOLD US HOW BAD IT COULD BE IF NOT ANY PERCAUTION TAKEN. I HAVE SMALL GRAND KIDS WHO LOVE PLANTS AND FLOWERS. THANK YOU SO MUCH FOR THE INFORMATION.

Hey succulentdude3, gently lift the stem from the soil and see if any roots have formed. If it looks rotted or otherwise unhealthy, try again. Be sure to let the cut stem end callus over before you plant it. Good luck!

I planted a stem+leaf about a month and a half ago in succulent/cactus soil. It hasnt grown at all. It gets sunlight a plenty. Why hasnt it grown? It's a wicked plant, nonetheless.

I needed to trim my donkey tail plants and found out that evening to have a major allergic reaction to it. I must of gotten some of the milky discharge from a broken stem on my face. It burnt and I had burning in my nose so I took Benadryl and when I woke up in the morning I had the face of death. My nose and area surrounding was swollen and inflammed. My chin had a patch with blisters and inflammation to it. The swelling went into my eyes. I was quite a site. The ER gave me some steroids and more Benadryl and sent me home. Good luck and wear gloves.

My brother in-law was trimming this plant (they live in Reno, NV) and some of the secretions from the Donkey's Tail got in his eyes. His eyes began to swell really bad so my sister called Poison Control and they told them to get him to emergency care right away. They kept him nearly 10 hours and sent him home with strict orders to call them back in two days to let them know how he was recovering. Two days later his vision is still blurred. Apparently he has a severe allergic reaction to this plant. The poison control center told them he could have gone blind if left untreated. Not a plant worth having in my estimation!

this plant was put forward as a possible cause of the death of my cat .Has anyone any evidence to the toxicity of this plant? Is it edible?

This is an excellent hanging basket plant. It requires little attention and grows quite rapidly. Although it can withstand some light freezes, I bring it in the house if the temperature falls below 25 degrees in order to keep the ends of the "tails" from receiving freeze burn. Do not overwater.

Thanks so much for the information posted! I received a piece of this plant from a nice woman who lived two houses down from a friend I was visiting. She didn't give me any information about this lovely plant nor did she give me the name of it. All she said was to stick the cutting and any "leaves" that fall off into dirt. I've been trying to grow more of it without success. Thanks to this site, I think I'll have a better chance now!

Very nice pictures and very well documented.

This plant is easily propagated from stems or just a single leaf dropped on sandy soil. It will root and sprout new "leaflets" in just a few days.

Burro's tail is a native of Mexico. It is an attractive, succulent plant for hanging baskets. The leaves have a silvery blue cast to them and the branches may reach 3 feet or more. It needs warm temperatures and full sun to partial shade. Plants should be watered on at least a weekly basis. The soil should be allowed to dry thoroughly in between waterings. Apply fertilizer once during the growing season. During its dormant period, water only enough to keep the leaves from shriveling.
