They have just released a new series of mesh potting plants that look absolutely gorgeous. There are 7 different pot/soil/plant/gardening tool combinations which are available separately for 100L each or in a fatpack for 350L. Each set has a land impact of 0.5, which means you can rez out a bunch of them and link them without compromising prim counts.
I also found a series of gorgeous tulips in a variety of tub planters. These are mesh, with a land impact of 0.5 per flower-filled tub. Each of the three styles is available for 100L. As with the potted plants, these would be a great way to add a splash of color and texture to your summer SL landscape.
