Patios and Walks Gallery Published on by Nate Little Lime Hydrangeas are starting to establish a great backdrop for perennials. The entryway has two pond mix accent areas installed to provide year round interest. A look at the space after gravel has been installed. We used Limestone Cobbles to retain existing stone mulch. Limestone wall stone was installed as a paver to match the step. The accent of the Limestone step compliments the Bluestone paving nicely. This patio was installed with Unilock materials for the inset and step. Decomposed Granite was installed for the walk with a Bluestone drainage channel.
