Boulder walls are a great element to use in garden design. They can be a short as one foot in height. Small boulders are simply lined up on a row with smaller rocks filling in the gaps between the larger stones. Walls like this can be borders, or they can be used to divide a large garden into zones.
"For soft gravel patios I like to use 3/4 inch round rock. I dig an area out flat so that I can spread it at least 3" thick and have the top be at the desired grade. I rake it smooth and hose it down to clean it. Instant patio! Pea gravel, which is smaller and more common, is an option too, but I find it sticks to the feet and in the soles of some shoes and gets tracked around. The 3/4 round rock tends to stay in place and is prettier. I never put landscape fabric underneath. Jeffrey Bale
I would like something similar to these pillars at the end of our driveway (no gate). Run electrical for the lights but also put in weather-proof outlets on the back to decorate for the holidays (wreaths/lights). I'd love to have them flanked by evergreen trees which could also be lit for the holidays. :)
