Time once again to go on Malta-star thistle patrol. Since 2012, we've managed to get this awful invasive species under control in our Wildscape. But I still have to monitor certain areas, mostly along the street easements in our front yard and adjoining Meadow. Allegedly, the seeds can remain viable for up to 10 years. You can search "Malta-star thistle" on this blog and read more about this AWFUL plant.
Don't EVEN get me started on BASTARD CABBAGE!
