I love love love perinnials! I plant both the flowering and non flowering sorts. I don't care for annuals, because I like plants that stay year after year. I am also a big fan of bulbs.
I just recently planted all the ground cover in my yard.. creeping thyme.. 216 little plants in between my flagstones. I also just planted some flowering vines.. royal purple trumpet vines, a scarlet one and two Clemetis plants. Columbines and a star jasmine also just went in. I planted a bunch of other things too. I am in zone 9.
I agree it is very therapeutic. Also, great exercise.
What are you planting this year?
