Zone 6 Crepe Myrtle Varieties – Growing Crepe Myrtle Trees In Zone 6

Crimson Cone Crepe Myrtle (Lilium lilium)

The Crimson Cone Crepe Myrtle is one of the most popular variety of crepe myrtle tree in the world. It grows in zones 5 through 8. Its name comes from its crimson coloration and it’s a very vigorous tree with a large root system. It produces a small number of flowers but they are not showy. They are rather inconspicuous and only bloom once every three years or so.

It is well known for its attractive foliage which is red, purple, pink, orange and yellow. The leaves grow up to six inches long and have five leaflets each. The twigs are usually dark green with four pairs of leaflets at the base. The branches are quite thick and reach up to fifteen feet in length. These are often used for shade.

It is easy to grow and requires little care other than regular fertilization and watering. It prefers full sun but will tolerate part shade better. It does best when temperatures range between 75 degrees F and 90 degrees F year round. If grown outside, it may get cold winters, however, it can handle them if given proper protection during the winter months.

It is a great choice for almost any soil conditions except poorly drained ones. It has a high drought tolerance and is fairly resistant to disease and pests. It does not do well when in contact with salt spray.

Yellow Trumpet Crepe Myrtle (L. lutea)

The Yellow Trumpet Crepe Myrtle is another popular crepe myrtle tree variety. It can be grown in zones 5 through 9 and prefers full sun. It can grow up to 20 feet in height with a trunk of up to 1.5 feet in diameter. It produces beautiful flowers and colorful foliage.

The leaves are green with yellow, pink and purple over tones. They reach up to 4 inches in length with three large pointed leaflets. The yellow trumpets reach up to 12 inches in length and are found on every single branch of the tree. This tree has a V-shape as it grows and produces lovely yellow flowers in the spring.

It is easy to grow and should be watered every ten days during its first year. It can tolerate a wide range of soil types and has a lower drought tolerance than other crepe myrtle varieties. It should not be exposed to salt spray or salty winds.

The Yellow Trumpet Crepe Myrtle is a good tree for providing shade in the summer as well as offering splashes of yellow color during the spring and summer months.

Rio Salado Crepe Myrtle (L. splendens)

The Rio Salado Crepe Myrtle is one of the most beautiful crepe myrtle tree varieties. It grows in zones 5 through 9 and prefers full sun to part shade. It is a fast growing tree with a beautiful blossom and colorful foliage.

The flowers are a lovely lavender color and often bloom in clusters. The leaves are quite large and have five to seven points. They are glossy green in color and can be up to 8 inches in length.

It is a good tree for desert areas as it has a high drought tolerance and can also tolerate salty coastal air. It should not, however, be placed in poorly drained soil as it will not tolerate standing water.

It should only be pruned to prevent it from growing into other objects or to maintain its shape. It has few disease or pest problems and requires very little maintenance once established.

It is the most cold tolerant Crepe Myrtle variety. It can grow in zones 8, 9 and 10 withstanding cold temperatures as low as 5 degrees F. It should be staked when young to aid in shaping and trained to grow a specific shape.

Sometimes known as the Bellflower Crepe Myrtle, the Rio Salado Crepe Myrtle is an excellent tree for desert areas and highly sought after due to its beautiful flowers.

If you live in an area with cold winters, you should look for a crepe myrtle that is specifically hardy in your area. Most will not tolerate temperatures below 15 degrees F. However, there are a few that can withstand colder temperatures.

These include:

Longfield – zones 6B through 9A

Hillier – zones 7B through 9B

Morrison – zones 7B through 9A

Rio Salado – zones 8A through 10

You should also look for a crepe myrtle variety that can grow in the soil types common to your area and that has a lower drought tolerance.

Many crepe myrtle varieties require a great deal of water to grow properly. If you live in an area where there is not a lot of rain, you may wish to consider one of the less drought tolerant varieties such as Hillier, Morrison or Rio Salado Crepe Myrtles.

You should also avoid planting a crepe myrtle unless you can give it at least five or six feet of space on all sides.

Crepe myrtles have very brittle branches which can break easily. Crepe myrtle varieties that grow six to eight feet tall include:

Hillier – zones 7B through 9B

Morrison – zones 7B through 9A

Rio Salado – zones 8A through 10

These varieties are also a bit less brittle than other crepe myrtle varieties. They can withstand higher winds as well as accidental contact with them.

If you have a little more room to work with and want a beautiful tree that is also durable, a crepe myrtle might be perfect for you. They offer a rich vibrant display of gorgeous flowers that are sure to fulfill your every gardening desire.

After planting, all you should need to do is prune it once a year in late winter to keep it the way you want. Crepe myrtles also have few major disease or pest problems. They are very easy to grow and maintain as long as they are planted in the right area and given proper care.

Once the crepe myrtle is established, it can actually tolerate drought conditions better than some other trees. It can grow in a wide variety of soil types and still look its best so it is perfect for people who are not skilled gardeners.

When choosing a crepe myrtle to plant you should consider how much space you have for the tree as well as your personal taste in flowers. Crepe myrtles come in a wide range of colors and sizes so you are sure to find one that is right for you.

You should also consider the amount of sun the tree will receive. Most varieties need at least six hours of sunlight per day in order to look their best. If they do not receive enough sun, they may fail to bloom or the blooms may be deformed.
