I would like to avoid having a house symbol in the picture as a friend with an indoor composting business has that in her logo. I like the idea of a window like this company ( http://www.indoorplantpeople.com ).It has to give the sense of being INSIDE though to focus on the INDOOR plants so a room setting is fine as well. 
 The English Ivy, Peace Lily, Heart shaped Philodendron are a few of the specific plants if their leaf shape could be considered: few links with the plants below

The colours green and blue would be preferred happy to consider shades. All other ideas welcome THANK YOU

Peacock braved going out of my logo description of what i though I wanted which I was open to and I am very grateful as it was much better than my ideas. I am very happy THANK YOU. Peacock did not give up on improving the design which was great as well.
