Can someone suggest a type of dwarf fragrant shrub that can be planted next to the porch? We live in South Carolina, in sand land. There are to many weeds to continually pull, so if I plant shrubs, I can mulch them. The area gets afternoon sun. I would love to have some dwarf gardenias, but I do not know anything about what would work. I love smelling fragrant flowers sitting on the porch at nite. Thank you for helping me.
