afrogalactic asked: Hi there! i love your collection! I'm also a succulent collector and just ordered Sedum morganianum. I've read some horror stories about allergic reactions to these plants online and am wondering if you've had any kind of issue with these plants. Thanks!
This question was quite a head-scratcher for me, as I’ve never had any trouble with my Sedum morganianum. I did a bit of googling around for these “horror stories” you were speaking of, and found some good examples in the Dave’s Garden entry for Sedum morganianum.
These caused further further confusion for me, though. “Sticky white discharge”? Inflammation? Danger to the eyes? It sounded like they were describing a euphorbia species, not my sweet little sedum. Then, looking through the “positive” entries, I found I was exactly right:

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)….
There’s the culprit, then. Our lovely S. morganianum is being slandered by people confusing it with E. myrsinites, a euphorbia that’s called by the the same common name. If you look through the negative comments, you’ll notice they all refer to “Donkey’s Tail” or “this plant” instead of the proper name.
Euphorbias are all toxic to some degree. For a thorough examination of euphorbia toxicity, check out “How Toxic are Euphorbias, Really?”
S. morganianum is, in my experience, an utterly harmless plant. I’ve never known it to excrete anything but a little clear, water-like liquid, and only enough of that to leave a damp spot on the stem. That’s not saying that nobody has ever been allergic to it, but it’s certainly not a menace. For the plant’s sake, I would advise caution when handling: it loses leaves ridiculously easily. These can be used to start new plants with a little patience, though.
Aren’t common names FUN?
