Most people wait until mid to late May to plant their containers because of a chance of cold snaps, but I have been busy planting for weeks using plants that are cold tolerant, using bulbs, cool season annuals and perennials. For my most viewed post ever on containers, check out Not Your Ordinary Container-Containers With Pizzazz!
Bulbs only last a few weeks, but you can easily slip them out of the container and plant in one of your garden beds for a show next year. Leaving an empty spot that you can plug-in some annuals for a warmer season, like verbenas and petunias, containers can be transformed with the addition and subtraction of several plants and emerge with a completely different look.
Violas are an early season staple that look good for about 6 weeks until the hot weather starts and then they are toast. See my post on Violas to see how many ways you can use this versatile plant. They give you a quick early boost of color which can be removed when the violas start to fade and then you can insert something more heat tolerant.
Mixing a melange of perennials, annuals, bulbs, and small shrubs early creates a container that will last through the season with tweaks throughout the year. Make sure that you take care of your container with good drainage, an essential for any plantings. I like to elevate my container off the ground so that it can drain properly. A plant stand or pot feet are perfect for the task.
Woodland Phlox is a great perennial that lasts for 6 to 8 weeks and is highly fragrant. When finished, pop it into the garden and replace it with something else blooming.
