We plant flowers every spring!
I like perennials, but, every year, there are usually 2-3 different annuals we plant as well.
We always have petunias on our back deck. (Petunias remind me of my grandmother.) In the front, we plant 5 plumbago plants. In areas just south of us, plumbago is an perennial, but, here, depending on how cold the winter is, it's normally an annual. We also planted some mandvilla in 2 pots on our front porch.
Oh, & do vegetables count? We purchased 2 potted tomato plants.
This spring, we did a little revamping of our front landscaping & planted more than usual. I decided we needed more height variations, so we added some succulents, cone flower plants, & some kind of blue flowering ground cover. I also replaced 2 Tea Rose bushes w/ Knockout Rose bushes & 2 lilac bushes w/ 2 Japanese Holly shrubs. (We transplanted the tea roses & the lilac to the back yard.) Oh, &, every year, we have to replace a couple of firewitch.
Oh, & we planted 5 blueberry bushes!
