<i>Calibrachoa </i>plant named ‘Docalblosu’

Abstract

A new and distinct cultivar of Calibrachoa plant named Docalblosu, characterized by its upright to outwardly spreading and mounding plant habit with plants eventually becoming trailing and decumbent; relatively vigorous growth habit and moderate growth rate; freely branching habit; early and freely flowering habit; relatively large flowers with white-colored petals with large greenish yellow-colored centers and yellow-colored venation; and good container and garden performance.

Claims
