A new and distinct cultivar of Portulaca plant named ‘LAZPRT1604’, characterized by its outwardly spreading to creeping growth habit; vigorous growth habit; freely branching habit; freely flowering habit; light yellow, red and red purple-colored flowers; and excellent garden performance.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofPortulacaplant, botanically known asPortulaca umbraticolaKunth, commonly known as Wingpod Purslane, and hereinafter referred to by the name ‘LAZPRT1604’.

The newPortulacaplant is a product of a planned breeding program conducted by the Inventor in Merano, South Tyrol, Italy. The objective of the breeding program is to create new vigorous and freely branchingPortulacaplants with numerous unique and attractive flowers.

The newPortulacaplant is a naturally-occurring branch mutation ofPortulaca umbraticolaKunth ‘Duna Purple Cross’, not patented. The newPortulacaplant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of ‘Duna Purple Cross’ in a controlled greenhouse environment in Merano, South Tyrol, Italy during the spring of 2014.

Asexual reproduction of the newPortulacaplant by terminal cuttings in a controlled greenhouse environment in Merano, South Tyrol, Italy since the spring of 2014, has shown that the unique features of this newPortulacaplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LAZPRT1604’. These characteristics in combination distinguish ‘LAZPRT1604’ as a new and distinctPortulacaplant:1. Outwardly spreading to creeping growth habit.2. Vigorous growth habit.3. Freely branching habit.4. Freely flowering habit.5. Light yellow, red and red purple-colored flowers.6. Excellent garden performance.

Plants of the newPortulacacan be compared to plants of the mutation parent, ‘Duna Purple Cross’. Plants of the newPortulacadiffer primarily from plants of ‘Duna Purple Cross’ in flower color as plants of ‘Duna Purple Cross’ have a less intense (lower contrast) flower color pattern that is unstable. In addition, plants of the newPortulacaare more freely branching than plants of ‘Duna Purple Cross’.

Plants of the newPortulacacan be compared to plants ofPortulaca oleracea‘Duet Rose Improved’, (U.S. Plant Pat. No. 16,152). In side-by-side comparisons, plants of the newPortulacadiffer primarily from plants of ‘Duet Rose Improved’ in the following characteristics:1. Plants of the newPortulacaare more compact than plants of ‘Duet Rose Improved’.2. Plants of the newPortulacaare more creeping than and not as upright as plants of ‘Duet Rose Improved’.3. Plants of the newPortulacahave larger flowers than plants of ‘Duet Rose Improved’.4. Plants of the newPortulacaand ‘Duet Rose Improved’ differ in petal color as plants of ‘Duet Rose Improved’ have yellow-colored petals with purple-colored centers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 13-cm containers during the spring and summer in an outdoor nursery in Merano, South Tyrol, Italy and under cultural practices typical of commercialPortulacaproduction. During the production of the plants, day and night temperatures ranged from 13.8° C. to 28.6° C. and light levels ranged from 60 to 70 klux. Plants were four months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.Botanical classification:Portulaca umbraticolaKunth ‘LAZPRT1604’.Parentage: Naturally-occurring branch mutation ofPortulaca umbraticolaKunth ‘Duna Purple Cross’, not patented.Propagation:Type.—By terminal cuttings.Time to initiate roots, summer.—About 10 days at temperatures about 22° C.Time to initiate roots, winter.—About 14 days at temperatures about 22° C.Time to produce a rooted young plant, summer.—About 24 days at temperatures about 22° C.Time to produce a rooted young plant, winter.—About 28 days at temperatures about 15° C.Root description.—Fine, fibrous; typically pale creamy white in color, actual color of the roots is dependent on substrate composition, water quality, fertilizers, substrate temperature and age of roots.Rooting habit.—Freely branching; medium density.Plant description:Plant and growth habit.—Spreading to creeping plant habit; vigorous growth habit; relatively rapid growth rate.Branching habit.—Freely branching habit with lateral branches developing at every node; pinching is not required.Overall plant height.—About 15 cm.Plant diameter(area of spread).—About 40 cm.Lateral branch description:Length.—About 30 cm to 50 cm.Diameter.—About 3 mm to 4 mm.Internode length.—About 2 mm to 20 mm.Strength.—Moderately strong.Texture.—Smooth, glabrous; succulent.Color.—Close to 148A underlain with close to 185B.Leaf description:Arrangement.—Alternate; simple.Length.—About 1.8 cm to 2.5 cm.Width.—About 9 mm to 15 mm.Shape.—Obovate.Apex.—Initially acute becoming more rounded with development.Base.—Obtuse.Margin.—Entire.Texture, upper and lower surfaces.—Smooth, glabrous; succulent.Venation pattern.—Pinnate.Color.—Developing leaves, upper surface: Close to 137A.
