Look like a political party that supports a landscapers' union.
Your priority of message is 80-90% - america, 10-20% - landscaping (maybe less).
I think it's coz of the colours and font. The colours say America obviously, and the font is very diplomatic - therefore it looks very bureaucratic as a whole.
If you're allowed to use the statue of liberty in your artwork, maybe use that, standing on a hill or something and integrate that into the name and make the message 1) landscape/garden 2) (statue of) liberty.
My opinion, the statue will help people associate/memorise the logo with the name, and the context of the image of landscape should then tie it up if done well.
Very clean and nice work though.
