Butter and Eggs (Linaria vulgaris) growing out of the gravel on abandoned railroad tracks.
what IS this butter n eggs that you and lady gardenpath (http://gardenpath.wordpress.com/2008/07/07/butter-and-eggs/) both have but that I’ve never heard of?! The wild yellow thing around central NY that’s tall and pretty turns out to be wild parsnip, whose most striking feature next to the delicate umbrel bloom may be the burn it causes if you get sap on you and then expose to sun. . . something not quite right about that.
Don’t you love it when the wild flowers show their colors! Very lovely!
Pretty, yes, but try to get rid of it! Linaira vulgaris is a noxious weed in Colorado,US. It was introduced as a pretty ornamental in the mid-1800′s, but has since displaced native plants and is difficult to control due to it’s extensive root system and effective seed dispersal. A noxious plant by all standards!
The invasiveness of a plant depends on where you live. What is highly invasive in one climate may not be considered a threat in another. Linaria vulgaris is category 4 in my region (with category 1 plants rating the most aggressive). This means it is on the list but is tolerated.
