Thank you so much for this site.But now im really scared,Hubbys horse was eating some of our confederit jasmin,a few days back.Should I call an tell my vet?What can i do,hes not sick or anything yet.
Some help me please

BornToRide · 01-28-2007, 06:03 PM

Well, I couldn't find this in the links, but I just thought I would add, the cherry tree leaves, once the rot into the ground, become toxic, so watch for those!!

mdvaden · 07-17-2007, 12:37 AM

I made pages for pet birds and horses.

What is interesting, was that for birds, the internet has a lot for both "safe" and "toxic".

On the other hand, the internet resources for horses leaned heavily toward "toxic" with very few documents or pages for "safe".

The nice part about the "safe" lists, is having suggestions at-hand.

This month, I may try to make a limited suggestion list for dependable, safe fast growing shade trees that would be good choices. Those that are relatively free from pathogens, affordable, and readily available.

For example, I know of a couple who waited almost 4 months once, to plant 'Red Obelisk' beech, because it took that long for a few Oregon nurseries to stock them. That would be the kind of tree to avoid putting on this kind of a list. Anyway, it would give people a good head-start.

Great Info! It is very helpful. It is Purdue though isn't it? Not Perdue.

TanyaV28 · 09-17-2007, 09:23 AM

I just looked at all of this. How scary. Im very nervous because my horse stormy is very ill. I dont even know if I have any of this. Im going to print the pics and go out in my pastures and check. Thank you

Sierra · 02-25-2008, 06:20 AM

Hi, has anyone heard of a weed/plant that is poisonous to cows called Night Shade, it has little purple/black flowers? My hubby told me as a kid he had to go around the pasture and pick them from the roots, he thinks that it had something to do with the cows milk. we are moving to a new place that has been empty for sometime, so before it gets mowed down I want to know if I chould pick them. Thanks Deb

seerfarm · 02-25-2008, 06:53 AM

Yes, Night Shade is poisonous.

I found a great link with a list of poisonous plants and there affects, hope this helps.

This is a great link as it not only lists poisonous plants but divides them up into families (by poison, whether it's the leaves or seeds, etc.)

I heard from my vet that oleanders are poisonous to horses. Here are some pictures. They grow wild and people plant them too. I heard they can grow all across the USA. I am not sure about other places but watch out for them!

They can also be dagerous to your cats and other pets.

Here is a close up so you can see how the flower is shaped.

fishing_trex · 08-13-2008, 11:50 AM

Update on link in OP: the UPenn link for poisonous plants is now:
http://cal.vet.upenn.edu/projects/poison/index.html

Also, I didn't see ragwort listed as a poisonous plant. It is highly poisonous to horses at ANY stage and kills hundreds of horses every year (Britain thinks the true number is closer to 6500). Although they tend not to eat it when it is green, when dried out, horses find it very palatable -- and when dried out, it has about twice the poison. Ragwort is common throughout much of the world. Once clinical symptoms appear, little can be done to save the animal.

It is also poisonous to humans, so if you plan to go pull plants from your pasture, wear gloves! And dispose of the dead plants carefully.

Here are some photos of ragwort (from http://www.natural-animal-health.co.uk/ragwort.htm)

I live in Arkansas and want to plant some sort of fast growing windbreak. Something like a hedge maybe but I can't find anything that is safe also. Anyone have any ideas?

Deadly Nightshade.

Red, turning to black berries. As the name says, this stuff is deadly, also toxic to humans, dogs etc. Pull it up by the roots (very shallow) and burn it.

Very useful lists, Thankyou. When I first came to Ontario I was reduced to wandering about the place with a camera in one hand and a "Weeds of Ontario" book in the other, didn't have a clue what half the plants were.

Nanking bush cherries or Hansen bush cherries are safe, and you can use the cherries for juice to make jellies and jams. I even made home made wine with them.
