What Flowers Bloom in September?

You may be wondering what flowers bloom in September. Although this is late in the season, many flowers will still be in bloom, not to mention the new flowers that are just beginning to emerge. It is possible for the September garden to be just as pretty and full of blooms as the June garden. The trick is to know what flowers bloom in September even if there is an early frost.

Fall Crocus

Crocuses are known as early spring blooming flowers. However, there are varieties of fall crocuses that bloom as the temperature begins to dip. There are many species of these fall blooming bulbs, so it is possible to keep them in bloom from August to December. Crocuses prefer to grow in full sun, however growing them in part shade will not damage the plant in anyway. The typical flower colors are purple, yellow and white. Most crocuses are 4 to 6 inches tall when in flower, so it is best to plant them at the front of the border. Crocuses grow from corms that should be planted 5 inches deep in fall. Over time, the tiny corms the will multiply, causing this flower to naturalize. Crocuses are hardy in USDA Plant Hardiness zones 4 to 8.

Lilium

Some cultivars of Oriental lilies such as casa blanca do not bloom until September. Other varieties of lilium will bloom in August and may still have blooms come September. Most lilies are highly fragrant and do best in the middle to back of the flower garden border because of their height, which can range anywhere from 18-inches to 12-feet tall. Most varieties range in height from 2-feet to 5-feet tall. Do not confuse the genus lilium, which are true lilies, with daylilies. Daylilies are in the Hemerocallis family. These are two different types of plants. True lilies grow from individual bulbs similar to a tulip bulb. The difference between tulip bulbs and lilium bulbs is tulip bulbs are smooth while lilium bulbs have overlapping scales with no protective covering around them. Most lilies are hardy in USDA zones 3 to 9.

Sedum

Sedum is a great plant for the fall garden. When choosing what flowers bloom in September, do not fail to pick up some sedum plants. White and pink are the most commonly seen flower colors on sedum. With more than 400 varieties of sedum available, there are flowers in every color imaginable except blue. The height of sedum varies considerably. There are ground covers as well as shrubs. The hardiness of these plants varies from topical varieties that cannot take frost to cold hardy varieties that cannot tolerate heat. Most varieties of sedum are hardy in USDA zones 3 to 8.
