The layout is looking really great. I wonder if we can work with the leaf image a little more to get something that is more meaningful to the identity of our company. Perhaps an abstraction of the solidago plant itself, see image at:
http://www.ayearinseattlegardens.com/wp-content/uploads/2012/10/soidago.jpg for an idea of the form of the plant. If this is going to work, it should be a very stylized abstraction of the plant form, not a direct copy.
Another benefit of this stylized image is that I think it could be interpreted many ways: A solidago flower, a river network, a network of paths in a park, etc.
Let us know if you have any questions.
Thanks!
