Pinellas County has no mountains, so in Clearwater a summit has to be built some other way: a garden that climbs from turf to shrubs to palms in easy steps, a front walk that draws the eye up to the door. Summit Group Professional Landscaping plans, plants and keeps up that kind of layered landscape. The right season for laying one out comes in the dry, bright stretch of winter, when the humidity lets go, the light turns clear and golden over Clearwater Harbor, and late February carries the crack of spring-training bats across town. That cool window is the time to shape new beds, set fresh plantings and tidy what already grows before the summer rains take charge. By the time the wet season arrives, the yard has its lines and its layers, and it wears them all year.
