hi meyerlemon
there are abought 39 types of lavenders..
im not an expert but we grow a bught 50 types of herbs
and abought 6 types of them are lavenders. so my guess is

pic # 3 looks like goodwin creek because half of the leaves
are rigid and the other half are not..and it has a
light soft collor.

pic # 2 looks like grosso?
only because of the flower and abought 1 inch down theres another flower.
the only thing i dont like is grosso looks more compact. but you might just have one that is streched.

pic # 1 looks like Spanish or french Lavender. i cant realy see the leaves from the pic ? are the leaves rigid or smooth ? is it real woody?
so from just looking at the flower it looks like spanish.

hope this helps...

Thank you very much boston3381, you sent a very detailed, helpful reply, more than I expected.
I checked other photos of each variety and I think you are right about them.

The variety in the first picture has very rigid leaves and yes, it is woody.It also has a yellow/green color instead of pale gray/green color. It is the one with the strongest smell. I hope these additional information helps.

Thank you :)

that first pic then might be a over-wintered french lavender. if you take it out of the pot is it root bound and are the roots hard as a rock?? allmost like wood??

Thank you again for your reply boston3381 :)

Unfortunately I am away from home and I can't check the root but it is ok to know that much for the time, you helped a lot.
