The Walter Andersen Nursery has a section of handy fliers customers can take for quick gardening information. One of my favorite fliers was a list of toxic and poisonous plants. It’s handy because it describes the specific plant part to be avoided. It always amazes me how many common plants are toxic and I have finally become a smarty pants and forced myself to wear my gloves more often in the garden, even though I seem to be constantly missing the left hand…who keeps taking my left hand glove?! Anyway, I was planning on typing it here so I would have the list to memorize, but I found it online so decided to cut and paste instead – with all due credit going to Walter Andersen for sharing this awesome and important information. Thank you! (also, I did not edit or proofread the list in any way so any spelling issues or missing Latin are not my bad…and my inner OCD wants to add a lovely photo of each plant, but I locked her in her room for the day)
