Big Lawn Tropical Front Yard
This big yard has a little too much lawn grass for any design style. The Tropical styles like the Mediterranean gardens get their atmosphere mostly from the plants used in the design. As you can see from the Palm trees in this front yard, that's pretty much it. Lawn grass is a neutral element that works in most landscapes. How much lawn is a matter of preference, time, and resources for getting the maintenance done.
