Then, continue reading the magazine on a back yard project with three cost solutions: low-end (ie, $5000, DIY), middle range ($50,000) and high-end ($200,000, which includes a pool). Landscapes by Mark Word Design in Austin, TX. The article is here.
And finally, where to get big trees for instant landscapes? I visited one of the nurseries featured in the article, here, a few years ago, while at an APLD conference. If you get the chance, take a trip to Armonk, NY some time (just north of the city) and visit Mariani Gardens. It's a jaw-dropping experience.
