You are very welcome!! I just happened to stop by and saw your post so it was fortunate that I was able to answer you so quickly. This is a rather inactive forum and I don't stop by too often in winter. Now that it's spring I stop more often to see if there are questions I can answer, but I don't run or own this forum.
That's a great site you found and I'm going to save it so I can use it to help others. I hope you will be able to id them all.
Now don't spend all of this week's grocery money on plants! ;)
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
