Gardeners' Notes:

I knew that there were some handling issues with this plant but felt comfortable enough to plant one. We also don't have any dogs or young children playing in our yard. We're in NM and I needed something for the south side, direct sunlight all day, kind of space. It's in a raised flower bed with no other plants around it. Below the bed the ground is covered with small pieces of volcanic stones. So once it fills up this space, there is no place else for it to go. It's perfect for the location. I have had it for almost 2 years and it really is quite an interesting plant, we call it Mr Octopus.

Hi! I acknowledge that this plant is DANGEROUS in the wrong hands, without the proper protection. Also, I realize that it is being banned in some states because the hazards that accompany the plant.
I fully agree that it should be expunged in these areas where it is a nuisance, the only thing that irked me was a picture I saw of a woman holding a garbage bag full of these guys ready to dispose/burn/whatever they're doing to eradicate them. Meantime, some people are trying to sell them for a pretty amount, while so many are being torn up and thrown away!
Well I'd just like to put this out there if it's acceptable: IF YOU HAVE ANY MYRTLE SPURGE THAT YOU ARE PLANNING ON TRASHING OR TEARING UP, I WOULD LOVE TO GET SOME SENT TO ME FOR MY COLLECTION PLEASE! I am a compete... read more

My puppy, being as playful as puppies are, was chasing a reflection and ran straight into the plant, face first. When we moved in, the plant was already there. We didn't think much of it until he broke out in hives all over his face, which soon began to spread on his legs and back. They just keep growing, and he is in so much pain. He is usually insanely hyper when people come over, and he didn't even budge when people came inside. All he is doing is sleeping and every so often, pawing at his face. Poor pup!

I have this in my rock garden where it can get a bit thuggish if you let it. I haven't found it to be disturbingly invasive - it has spread around the immediate vicinity. I will use care in the future when I'm jerking out the extras, but I've never had a skin problem with this one and I'm highly allergic to poison ivy.

Last fall, I volunteered at the local woman's shelter and took home a little plant that was struggling. I told them I would overwinter it and would replant it if it looked like a keeper. It took off with a little care in my sidewalk bed and flopped over half the width of the sidewalk. I decided to trim it back about a month ago and broke off half the stems with my bare hands. No reaction. Reading all these reports makes me realize I was very fortunate. I'm not pulling the whole plant but will watch it carefully and likely move it to a less traveled area. I do have grands... and no, I'm not returning it to the shelter as there are often kids staying there.

I use this plant extensively in my own sandy soil by a lake in central Oklahoma. I also planted it in a raised planter on the highway where we have a sign for the lake. We have to carry water to the planter and because of that it is ideal as it survives our dry hot heat. I have a large rock, some day lillies and the spurge in the top layer of the 4 by 8 planter. The bluegreen color reminds me of the color I wish our lake was but since this is Oklahoma, that's not happening. The center does seem to die back every year and I simply break off a few pieces on the edge and stick them in the ground where needed and they fill in the empty space in no time. I usually don't wear gloves and have never had any dermatitis from the plant. I am allergic to poison ivy so I do not have a strong immu... read more

Please be WARNED!! The toxins are so real. I had this plant growing along the edge of my pond and trimmed it. My 30, 13+ year old fish were all dead this morning. It only took 12 hours to kill every one of them!! I had no idea this could happen. That plant has been growing there for years but of course this year it was just bigger. Please DO NOT USE THIS PLANT. So sad and heartbroken!!

I have quite a bit of this growing in my flower beds. On the positive note, it does grow anywhere...I have a lot of terrible dry soil under a Juniper tree and its great there. The bad part is its horrific if you get the sap on you. I knew the risks and still trimmed it back yesterday, paying special attention to not getting sap on me. I came in the house afterwards, and washed up very very good, on my arms and hands. About 2 hours later, my face felt on fire. I neglected to recall I had touched my face while working outside and now I feel like I have a bad sunburn. Hurts to touch. Woke up this morning and my face is really swollen in areas.

I am chiming in from West Jordan UT. We have this awful ground cover in our yard. The lady that lived here before us, planted it, because I am sure that is so pretty and nice to look at.

We really liked it too, until My Husband had to go to the emergency room one night, because his eye were so inflamed and burning, that the Doctor had to irrigate his eyes and put medicine in them.

I just got a small amount of sap on my eye and it was burning like crazy. This stuff does grow like a weed, and will take over.

Now we are faced with the task of getting this stuff out of our yard.

Here in Southern Ontario, Canada, I've come to expect this plant to be somewhat invasive, seeding itself easily, but for years have tolerated a few plants for their looks. Yesterday I pinched back the stems with bare hands on one plant with no problems. Today I did the same on another plant and even tho I washed the sap off my hands with soap and water as plain water didn't budge the gummy stuff, I must have gotten some in my eye. My eye has been burning for a couple hours now and my nose is running and also burning. I've rinsed my eye with cold water and used antihistamine drops with little relief. I hope I don't have to get further medical treatment. When this is over, the plants are all going to be pulled up and put in the garbage. This is no fun!

When I first got this plant I loved it. I now know it's horrible. Spreads everywhere, gives me an itchy unsightly rash, and looks horrible after seeding. Don't do it. EVER. Hard to get rid of because it can be so prolific. Although seeds are heavy, the plant pops them in the air on breezy days and they go flying!!! First plant I really hate, and I grow a lot of things people generally don't like....!

This plant is awful. Do not be tantalized by it's ease of growth and interesting look.

First, the infestation. Here in Utah, it takes over entire slopes and kills other plants. Last year I pulled enough to fill 30 lawn bags, turning my steep backyard into a naked pile of dirt. Finally this spring I see just a few natives starting to reclaim the ground they lost. I don't know anyone here who has easily controlled this plant in their yard.

Second, the sap. Even in states where it's easier to control, I have heard of very few gardeners who enjoy the rash. I had to go home sick from work once because the sap got on my hands and then somehow my face while I was weeding. If it gets in your eye, the infection can be critical.

Because of the many warnings about the sap I did wear gloves and had the trash bag at my side. I disposed of the cut back plant but some sap obviously must have fallen on other nearby plants I was trimming.

My eye is inflamed, my cheek is hot and it does extend to my ear and my lips. Clearly with the heat of the day and via sweating the tiny portion of sap has caused these problems.

I would avoid the plant completely.

Absolutely **erradicate** this weed but think twice about doing it by hand. I'm going to use pesticide.

While trying to remove this noxious weed I must have gotten a small amount of sap on my forehead which sweat brought down to my eye.This is probably the 3rd most pain I have ever felt.

I had taken several precautions as I knew the plant's sap was quite venomous. Head covering, gloves, eyewear, etc.

I am glad I did not get more and prolonged exposure as my eyelid is on fire and to a lesser amount my outer eye. After an eyewash and drops the pain is really only minimally better. My cornea seems fine. I am not really swelling although my nose did begin to run a bit.

I will have to head into ER if this is going to persist.

I bought a small plant on Saturday and dropped it home before continuing my shopping. I know I touched the plant, although there wasn't any sap leaking from it. During my shopping, my left cheek started to itch and I later broke out into a small rash on that side. it seems I may have been fortunate to get away with so little!

I'm still new at growing things and I like to buy different plants to experiment with (ie, see if they can survive ME) so I'm going to see if the nursery will exchange this for something else.

Thanks for the info from other posters, very helpful.

I was given a couple of these in the fall of last year by a friend, who described them as a self-seeding foliage plant. I wasn't sure if they would establish themselves enough to make it through the winter, since I was planting them so late. I was pleased to see this spring that they not only started growing, but even had small yellow flowers, which developed little orange centers! (I hadn't looked at all the photos on this site yet, so I wasn't expecting flowers.) The shape of the leaves does add interest to the garden. When I was planting them, I did handle the outer surfaces of the plants, but no sap since nothing broke. No allergic reactions so far, but as far as I can remember, my friend and I have not come in contact with the sap yet.

ok, i can understand how people can say that this plant is invasive but here in my yard in Holland MA i would not consider it invasive. Maybe because the majority of the land here is hard soil , clay soil with sand. i dont know. It has taken over 8 years for this plant to produce a few small colonies of maybe 5-6 plants each. They are easy to dig up and remove. i have had that milky substance on my hands and even went without washing my hands for a few hours. I did not know about the threat it has. But im starting to wonder if people are just allergic to it and im not? ive handled this plant many times bare handed and had no problem. that i said it.... NOOO...not gonna go there.

I purchased this plant at a local garden center last spring. It did not have an identification tag. I have enjoyed it immensely. BUT, yesterday I picked off a few stems. A milky substance dripped on my hands. I immediately washed my hands thoroughly! Later in the day I felt like I have a jalapeo burn on my lips. Several hours later my whole face was on fire! Today I look like and feel like I have been burnt. I know I did not rub this stuff on all over my face. This stuff is treacherous. It took me a few hours to research this plant. I think I will be more careful in my new plant choice in the future. I plan on telling the local garden center what I found. This is a great web site. ...glad I found it.

A friend gave me a small E. myrsinites to plant in an area under a porch roof in complete shade to cover a low, poorly constructed concrete wall. It did this job amazingly well in spite of the fact it is not mat-forming. It flowers and probably does produce seeds but I have never seen one. We get gale-force winds here in the coastal area of southern B.C. so I frequently have to untangle its branches. I never knew that this was harmful to skin because I never suffered any ill-effects. If the wind did break or damage a stem, I just cut it back. I love the colour and the unusualness of this plant and was sorry to learn it was such a 'weed' elsewhere.

Myrtle Spurge is not native to Colorado, but was brought here for ornamental planting.

According to the Adams County Parks Department, Myrtle Spurge is growing aggressively across Colorado. However, it is ILLEGAL to have it, so if it is in your yard, you are REQUIRED BY LAW to remove it.

To get rid of it you should dig it up and put in a plastic bag to avoid spreading seed and put it the trash. You can also kill Myrtle Spurge by spraying with 2, 4 D. You should wear gloves, long sleeves and long pants while working around the weed.

You should not cut Myrtle Spurge with a lawnmower because it spreads the seeds."
