I love to landscape and most of all, when a designer makes it easy with low prims. One of my favorite designers is Tm:.Creation whose new design is called "The Daisies Stump" Garden Arrangement +Opt PBR. GM66 which has so much to look at.. flowers, rocks, bushes, ferns, and an artful wooden sculpturesque stump as a centerpiece is so easy to integrate into just about any landscape. Best of all it has butterflies as a particle effect that can be turned off or on... turn it on is my advice, The build is only 10 prims and is m.3.5 wide x 2.8 deep or so. You can also unlink all the pieces and create your own garden.
