this is an even better alternative:
Landscape VW symbols: I placed a link to what I mean: better than words actually

I'm using it and got many compliments from my clients (...and some fellow gardendesigners). It's really artistic, many symbols, differtent colors, thought of everything! and great support.
It saves me a lot of time !!!! Speeds up the whole process for me.
Hoep you find it interesting.
great forum guys
