  • Cleveland's sage - Growing 2 to 3 feet tall and 4 to 6 feet wide, this sprawling perennial has whorls of purplish white flowers that appear again and again on its wispy stems, along with richly fragrant foliage.
  • Red annual salvia - This is a small bedding annual plant with crimson red blooms that typically grows about 12 inches tall; cut off the flower stalks as they fade and it will bloom over and over as long as the weather is hot.

It's not hard to find gardens exploding with color in June and July, but so often they look drab come August and September. Add a few these species to your summer selection to end the season with a bang.

Canna Lily

These are very tropical-looking perennial plants with 1 to 2 foot long thick, glossy leaves and flowers that come in almost every color of the rainbow. The stalks grow from tuberous roots each spring and take all summer long to reach their full height of anywhere from 4 to 6 feet before blooming.


Mums, as they're so affectionately called, take a while to get to the flowering stage, but they put on a bold display once it arrives. This usually occurs in August or September and lasts well into fall. Mums are compact, low-growing perennials that become completely covered in button-like flowers and are available in an astonishing array of colors.
