Portulaca Cultivar Named 'DPORMPZPUP'

Abstract

The invention relates to the field of Portulaca oleracea, specifically, the variety designated ‘DPORMPZPUP’. The variety ‘DPORMPZPUP’ is characterized by its controlled, semi-trailing plant habit, with free branching and vivid purple flowers. The present invention relates to plant parts, including cells and any propagative material of the new variety ‘DPORMPZPUP’, and use of any of the plant parts for reproducing the new variety ‘DPORMPZPUP’. The present invention relates to methods using any plant parts or progeny of ‘DPORMPZPUP’ for the purpose of deriving additional new Portulaca varieties. The present invention relates to seed, plants and plant parts produced by crossing ‘DPORMPZPUP’ with any other Portulaca variety or other plant. The present invention also relates to methods to produce new varieties of Portulaca oleracea using the variety ‘DPORMPZPUP’ and applying plant breeding techniques.
