Morus rubra 'Collier'

Common Name(s):

Description

 

Collier red mulberry is a native tree species and has both edible and ornamental features. It is a hybrid between red mulberry and white mulberry. It can live up to 125 years but the weedy invasive character is not appealing. It is more cold hardy than black mulberry.

Female trees are often considered undesirable in urban areas because the fruit is messy and stains pavements, automobiles and areas around the home. Stains may also be unwittingly brought indoors on the bottom of shoes. Do not plant this tree in the home landscape if you object to the mess typically caused by the fruit. Non-fruiting cultivars of the similar M. alba may be a better choice.

Insects, Diseases, or Other Plant Problems: Borers may be a problem particularly in the South. Whiteflies mass on some trees. Bacterial blight may kill foliage/branches. Coral spot cankers may cause twig dieback. Bacterial leaf scorch, powdery mildew, root rot, and witches broom may also occur. Watch for scale, mites, and mealybugs. Weedy self-seeding and messy fruit are concerns.
