Flowering Plants

Kansas is a state located in the Midwestern region of the United States. The state has a variety of landscapes, from tallgrass prairies to Flint Hills and lowland marshlands. The climate in Kansas is also variable, with hot summers and cold winters. Because of this, the state has a wide variety of flowers that can be planted.


Annuals are the workhorses of the flower garden, providing color and interest from spring until fall. They are easy to grow and care for, and they come in an almost endless variety of shapes, sizes, colors and textures. They can be planted in beds, borders, containers, alone or in combination with other annuals or perennials.

There are two types of annuals: those that are grown from seed and those that are grown from transplants. Seeds can be sown directly in the garden or started indoors. Transplants are young plants that have been started from seed indoors and then moved outdoors when they are big enough to plant.

Some annuals will self-seed, which means they will drop their seeds at the end of the season and come back the following year. If you don’t want them to self-seed, you can deadhead them (remove the spent flowers) or wait until after they have bloomed and then cut them back hard.


Perennials are flowering plants that live for more than two years. They are a great option for gardeners who want to have blooms year after year with minimal effort. Once they are established, they will come back on their own each spring, often getting bigger and better every year.

There are many different types of perennials, and they come in a wide range of colors, sizes, and shapes. Some bloom for just a few weeks in the spring, while others bloom all summer long. There are even some that bloom in the fall!

Perennials can be planted in the spring or fall. Spring-planted perennials will usually bloom earlier in the season than those planted in the fall, but both will provide years of enjoyment.

Here are some of the most popular perennials for Kansas gardens:

· daylilies (Hemerocallis spp.)
· irises (Iris spp.)
· lilies (Lilium spp.)
· peonies (Paeonia spp.)
· phlox (Phlox paniculata)
· rudbeckia (Rudbeckia hirta)
· shrimp plant (Justicia brandegeeana)

Best Time to Plant

Many flowers can be planted as late as early May and still do well. Some exceptions to this are annual flowers that require a lot of heat to mature, such as marigolds, impatiens, and zinnias. These should be started indoors in late winter and planted outdoors after the last frost date.
