Hi All, Started a major front yard project, built a retaining wall, water feature (still in progress), and laid out a dry creek. Looking to create a spectacular "exotic" garden. Finding out Zone 4 (Chanhassen, MN), appears to limit many types of plants I find appealing, e.g., Japanese Maples. Looking for shrub and plant suggestions. Prefer the more spatial look Vs packed together appearance. Started the process but long way to go. Appreciate and look forward to being guided along. Thanks in advance.
