Blue flowers are some of the most striking plants around and can add a rich splash of color to any garden. Plant them in a cluster of all blue or mix them in with other flowers for a rainbow of color.

When planting flowers, it is important to remember to follow the instructions on the tag for the plant. Always buy plants that will thrive in the conditions in which you intend to grow them. A plant that loves sun won't do well in a shady area and you will only be disappointed with the results.

When planning your garden, be aware of the bloom time of the flowers. Planting perennials with different bloom times near each other will insure a garden that has blooms all season long. Remember also to plan for the height of the plants, putting the taller ones in the back.
