plant named ‘DPAZ15’
A new and distinct Portulaca cultivar named ‘DPAZ15’ is disclosed, characterized by abundant flowering and an intense orange/red flower color. The new variety has a compact, semi trailing growth habit and forms a low, spreading plant. The new variety is a Portulaca, normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Portulaca oleracea.
Variety denomination: ‘DPAZ15’.
BACKGROUND OF THE INVENTIONThe new Portulaca cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Portulaca varieties for ornamental commercial applications. The cross resulting in this new variety was made during September 2008.
The seed parent is the unpatented, proprietary seedling variety referred to as Portulaca oleracea ‘PT-8-441’ The pollen parent is unknown, as the crossing resulting in ‘DPAZ15’ was an open pollination, with unidentifiable pollen parents. The new variety was discovered in June 2009 by the inventor in a group of seedlings resulting from the 2008 crossing, in a research greenhouse in Moshav Mishmar Hashiva, Israel.
Asexual reproduction of the new cultivar ‘DPAZ15’ by vegetative cuttings was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel in July 2009 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONThe cultivar ‘DPAZ15’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DPAZ15’ These characteristics in combination distinguish ‘DPAZ15’ as a new and distinct Portulaca cultivar:
-
- 1. Highly floriferous
- 2. Compact and dense semi trailing habit
- 3. Low spreading growth habit
- 4. Intense red/orange flower color.
Plants of the new cultivar ‘DPAZ15’ are similar to plants of the seed parent, Portulaca oleracea ‘PT-8-441’ in most horticultural characteristics, however, plants of the new cultivar ‘DPAZ15’ have a more compact plant habit, and more flowers per plant. Additionally, the new cultivar begins flowering earlier and produces more lateral branches than the seed parent.
COMMERCIAL COMPARISONPlants of the new cultivar ‘DPAZ15’ are comparable to the commercial variety Portulaca ‘BALRIORG’ U.S. Plant Pat. No. 17,421. These Portulaca varieties are similar in most horticultural characteristics, including flower color and form. The new variety ‘DPAZ15’ differs in having more flowers, per plant, larger foliage and a more mounded, dense plant form than ‘BALRIORG’. Additionally, the new variety has a more intense and homogenous flower color.
