Claims
I claim:
1. A new and distinct cultivar of Leucadendron plant named `Hawaii
Sunrise` as described and illustrated herein.
Description
Genus and species: Leucadendron stelligerum x discolor.
Variety denomination: `Hawaii Sunrise`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new variety of Leucadendron
stelligerum x discolor, hereinafter referred to by the cultivar
name `Hawaii Sunrise`. `Hawaii Sunrise` is a hybrid selection which
originated from the inventor's breeding program in Kula, Hi. The
genus Leucadendron is a member of the Proteaceae or Protea family
which is a significant commercial class of Mediterranean plants
used as cut flowering stems and ornamental container plants.
The inventor commenced his Leucadendron breeding program in 2011.
The objective of the breeding program to develop small or dwarf
types of protea for the worldwide container ornamental plant market
with novel foliage colors, superior growth habits for commercial
cultivation and for home gardener use.
In 2012, the inventor carried out controlled pollination between an
unnamed and unpatented plant of Leucadendron discolor as the male
parent and an unnamed and unpatented plants of Leucadendron
stelligerum as the female parent. `Hawaii Sunrise` was selected as
an individual in spring 2013 for its bright yellow flowers and
naturally compact and branching and secondary branching habit.
The inventor first asexually propagated `Hawaii Sunrise` in May
2014 in Kula, Hi. using semi-ripe tip cuttings. `Hawaii Sunrise`
has been found to remain stable and uniform and to reproduce true
to type in successive generations of asexual reproduction. `Hawaii
Sunrise` has not been sold or made publicly available more than one
year prior to the filing date of the instant application.
SUMMARY
The following traits have been repeatedly observed and represent
the distinguishing characteristics of `Hawaii Sunrise`. In
combination these traits set the new cultivar apart from all others
existing varieties of Leucadendron known to the inventor. `Hawaii
Sunrise` has not been tested under all possible conditions and
phenotypic differences may be observed with variations in
environment, climatic, and cultural conditions, however, without
any variance in genotype. 1. `Hawaii Sunrise` exhibits a very
compact bushy plant habit. 2. A one-year old plant of `Hawaii
Sunrise` is approximately 30 cm in height and 30 cm in width. 3. A
four-year old plant of `Hawaii Sunrise` is approximately 65 cm in
height and 65 cm in width. 4. The foliage of `Hawaii Sunrise` is
densely packed with pairs of leaves every 6 mm. 5. The stems of the
current year's growth of `Hawaii Sunrise` are bright red in color.
6. `Hawaii Sunrise` branches prolifically once established. 8 to 12
branches are formed each year on the previous year's wood. 7. The
terminal inflorescences of `Hawaii Sunrise` are borne on every
current season branch and are very numerous. 8. Each inflorescence
of `Hawaii Sunrise` bears showy bracts which are yellow in color
with contrasting bright orange-red coloration to their apex and
margin. 9. `Hawaii Sunrise` bears only male flowers which are
bright yellow in color. 10. `Hawaii Sunrise` prefers humus rich,
acid, well-drained medium, which is low in phosphorus.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying drawings illustrate the distinguishing traits of
the new Leucadendron cultivar `Hawaii Sunrise`. All plants in the
drawings have received one pinch after initial cutting
establishment. The plants have been grown without any chemical
growth regulators. The drawings were made from digital photographic
images. Although colors may appear different from actual colors due
to light reflectance, they are as accurate as possible by
conventional or digital photography.
FIG. 1 depicts a three-year old plant of `Hawaii Sunrise` in late
March. The plant has been grown outdoors in Oxnard, Calif. At this
time of year, the foliage color of `Hawaii Sunrise` is olive green
becoming deep purple towards and at the terminal growth.
FIG. 2 depicts a close up view of the terminal shoot growth of
`Hawaii Sunrise`, and newly-emerged male flowers in mid-late
March.

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY
`Hawaii Sunrise` differs from the male parent Leucadendron discolor
by foliage and stem color and by overall size. Whereas `Hawaii
Sunrise` exhibits bright red stems and leaf colors which range from
green to plum, the male parent Leucadendron discolor bears green
leaves on green stems. In addition, whereas `Hawaii Sunrise` grows
to 65 cm in height and 65 cm in width, the male parent Leucadendron
discolor grows to 2 m to 2.5 m in height and 1.5 m in width.
`Hawaii Sunrise` differs from the female parent Leucadendron
stelligerum by foliage color and plant size. Whereas `Hawaii
Sunrise` bears green foliage, the leaves of the female parent
Leucadendron stelligerum are yellow and red in color. In addition,
whereas `Hawaii Sunrise` grows to 65 cm in height and 65 cm in
width, the female parent Leucadendron stelligerum grows to 1.5 m in
height and 1 m in width.
`Hawaii Sunrise` may also be compared with the inventor's variety
of Leucadendron Plant Named `Hawaii Magic` (U.S. Plant Pat. No.
29,636). Whereas `Hawaii Magic` exhibits dramatic foliage color
changes during the season, from green to orange-red to plum, plants
of `Hawaii Sunrise` exhibit green foliage with many more current
year branches and therefore terminal inflorescences.
