In the spring, many of us buy those tried-and-true annuals that provide floral interest all summer long.
Think geraniums, violets, marigolds, and of course, petunias. It’s hard to imagine a trip to the nursery in the spring without picking up a hanging basket (or three) filled with vibrant bloomers.
It’s also a reliable mark of the coming winter when we gather up those hanging baskets and toss their contents into the trash or the compost bin.

Plus, you can save a hunk of cash.
