A new invasive plant has made it to Texas. It has only been spotted with verification nine times in the state, and one of them is in Milam County. The other eight are in a small area of Burnet County.
During the field trip to the McCormack Purple Martin conservation place, I took a photo of a flower I had not seen before. Of course I put it on iNaturalist. It got one “favorite”, but it couldn’t be verified as the Viper’s-Bugloss (genus Echium ) I had chosen to identify it. I had noted that I wasn’t sure, but it looked just like it.
Then an iNaturalist ecologist took note of it. He was very concerned about it, and he asked if I would go and take more photos of it for verification purposes. The gentleman has a PhD from the University of Texas and is a retired Wildlife Biologist at Balcones Canyonland NWR.
Mike McCormack said I was welcome to do that. I met him out there last Saturday and we went looking for some. McCormack noted that they had been dying out when I called, so he watered for me where he knew a cluster of them to be growing. They were blooming. The blossoms were smaller than the one I had seen earlier and had different colors.
The ecologist had warned me to wear heavy gloves and not touch them otherwise. They sting severely and cause a rash. You’ll see an ungloved hand in one of the photos. That’s Mike. He had handled them before and he said it wasn’t that bad, but they do cause an uncomfortable rash. I didn’t risk it. Mike said he first noticed them two years ago. He didn’t know their name until now. His theory is that they were transferred here via a pair of Black-bellied Whistling Ducks that were nesting in a tree above the main site of their location.
I posted several more photos, and the ecologist verified that they are Viper’s-bugloss plants.
They are native to Europe and temperate Asia. They are used in landscaping in a few European countries. They have been spotted in the northern United States and some other countries that didn’t use to have them.
These plants are actually harmful to horses and cattle because they produce a type of Alkaline that harms their livers. The ecologist recommended strongly that “the plants should be herbicided and dug out, bagged, and disposed of – being very careful not to drop any seeds.”
Years ago in Asia, they were thought to resemble snakes on some parts and were used to treat snake bites. Needless to say, that practice fell by the wayside. If you see any, it’s advised you remove them quickly – wearing heavy gloves.
