There was a small aritical in todays flume located in "letters to the editor" that indicated a toxic weed (Hoary Alyssum) spreading threw the bailey area. In regards to the horse community we are sending the info out because the weed is toxic to horses and can remain toxic dry for up to nine months! We will post the articals here in a while for anyone to veiw. Scincerly,
Here is a photo of a mature hoary alyssum plant (the scientific name is Berteroa incana, in the mustard family) taken near Bailey.
As you can see in the photo posted earlier in this topic, the flowers are clustered at the tip of each stem, with developing fruits all along the stem below. The leaves are simple, and slightly sticky. The younger flowering plants are single stems, as in the photo posted earlier, and seedlings are low-growing rosettes of green leaves.
The only local plant you could confuse it with is western yarrow, but yarrow has flat-topped flower clusters and frilly leaves:
In our area, seeds of hoary alyssum will be maturing soon. Now is the time to go after the flowering plants. When pulling by hand, be sure to get at least the root crown, or the plant will simply make a new shoot from the remaining taproot (which can be very deep, as Alan Swarz mentions in his letter to the Flume).
