A new and distinct cultivar of Anigozanthos hybrid plant named ‘Ramboblitz’, characterized by its dark orange-colored flowers with a medium sized perianth tube, medium plant height with an upright growth habit, and a long natural flowering season.

Latin name of genus and species of plant claimed:Anigozanthoshybrid.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct perennial variety ofAnigozanthoshybrid, which has been given the variety denomination of ‘Ramboblitz’. Its market class is that of an ornamental plant. ‘Ramboblitz’ is intended for use in landscaping and as a decorative plant.

The new cultivar originated in a controlled breeding program in Tuggerah, New South Wales, Australia during October 2003. The newAnigozanthoshybrid cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietaryAnigozanthoshybrid breeding selection designated A02-1697, not patented, characterized by its orange-colored flowers, green-colored foliage, and dwarf growth habit. The male (pollen) parent of the new cultivar is the proprietaryAnigozanthoshybrid breeding selection designated A02-1686, not patented, characterized by its orange-colored flowers, green-colored foliage, and compact, spreading growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during Mar. 2006 in a controlled environment at Tuggerah, New South Wales, Australia.

Asexual reproduction of the new cultivar by in vitro propagation of micro-plants since Jun. 2006 at Tuggerah, New South Wales, Australia has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Ramboblitz’ as a new and distinct cultivar ofAnigozanthoshybrid plant:1. Dark orange-colored flowers with a medium sized perianth tube;2. Medium plant height with an upright growth habit; and3. A long natural flowering season.

Plants of the new cultivar differ from plants of the possibleAnigozanthoshybrid both the female and male parents primarily in having a greater number of infloresecences and a shorter inflorescence length.

Of the many commercially availableAnigozanthoshybrid cultivars, the most similar in comparison to the new cultivar is ‘Bush Spark’, U.S. Plant Pat. No. 15,328. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Bush Spark’ in at least the following characteristics:1. Plants of the new cultivar are taller than plants of ‘Bush Spark’; and2. Plants of the new cultivar have a longer inflorescence length than plants of ‘Bush Spark’; and3. Plants of the new cultivar have a darker orange overall flower color than plants of ‘Bush Spark’; and4. Plants of the new cultivar have a weaker degree of perianth lobe reflexing than plants of ‘Bush Spark’.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed botanical description of a new and distinct variety of anAnigozanthoshybrid ornamental plant known as ‘Ramboblitz’. Plant observations were made on plants grown in Tuggerah, New South Wales, Australia. Unless indicated otherwise, the descriptions disclosed herein are based upon observations made from January 2008 of mature ‘Ramboblitz’ plants grown in nursery pots in greenhouse and outdoor growing areas with day temperature ranging from 25° C. to 27° C., night temperatures ranging from 6° C. to 8° C., and light levels ranging from 6 to 8 klux. Plants were grown for about 24 weeks with one plant per 20 cm container. Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, younger plants. ‘Ramboblitz’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may vary with variations in the environment such as season, temperature, light quality, light intensity, day length, cultural conditions and the like. Color notations are based on The Royal Horticultural Society Colour Chart, of The Royal Horticultural Society, London, 2007 edition.Botanical classification:Anigozanthoshybrid cultivar Ramboblitz.Parentage:Female parent.—ProprietaryAnigozanthoshybrid breeding selection designated A02-1697.Male parent.—ProprietaryAnigozanthoshybrid breeding selection designated A02-1686.Propagation:Type.—In vitro propagation of micro-plants.Time to initiate roots, summer.—About 7 to 10 days at temperatures of 25° C.Time to initiate roots, winter.—About two weeks at temperatures of 15° C.Time to produce a rooted young plant, summer.—About 45 to 60 days at temperatures of 25° C.Time to produce a rooted young plant, winter.—About 55 to 70 days at temperatures of 15° C.Root description.—Fibrous, freely branching and white in color.Rooting habit.—Freely branching.Plant description:Plant and growth habit.—Inverted triangle; compact, upright and outwardly spreading plant habit with tertiary branched flowering stems with predominately dark orange-colored flowers.
