Description

Description

Genus and species: Leucadendron salignum x discolor.

Variety denomination: ‘Hawaii Magic’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new variety of Leucadendron salignum x discolor, hereinafter referred to by the cultivar name ‘Hawaii Magic’. ‘Hawaii Magic’ 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 upatented plant of Leucadendron discolor as the male parent and Leucadendron salignum ‘Red Devil’ (unpatented) as female parent. ‘Hawaii Magic’ was selected as an individual plant in 2013 for its bright yellow flowers and naturally compact and branching and secondary branching habit.

The inventor first asexually propagated ‘Hawaii Magic’ in 2013 in Kula, Hi. using semi-ripe tip cuttings. ‘Hawaii Magic’ has been found to remain stable and uniform and to reproduce true to type in successive generations of asexual reproduction. ‘Hawaii Magic’ 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 Magic’. In combination these traits set the new cultivar apart from all others existing varieties of Leucadendron known to the inventor. ‘Hawaii Magic’ 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 Magic’ exhibits a compact bushy plant habit.
- 2. A two-year old container-grown plant of ‘Hawaii Magic’ is approximately 65 cm in height and 45 cm to 50 cm in width.
- 3. The foliage color of ‘Hawaii Magic’ changes from olive green in summer months to orange-red in the fall and becoming more intensely plum colored towards early spring.
- 4. ‘Hawaii Magic’ achieves its most striking foliage color in conditions of full sun.
- 5. The stems of ‘Hawaii Magic’ are bright red in color.
- 6. ‘Hawaii Magic’ bears only male flowers which are bright yellow in color.
- 7. ‘Hawaii Magic’ 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 Magic’. All plants in the drawings have received one pinch after initial cutting establishment and a second pinch approximately one year later. 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.

‘Hawaii Magic’ differs from Leucadendron discolor by foliage and stem color and by overall size. Whereas ‘Hawaii Magic’ exhibits bright red stems and leaf colors which range from green to plum, the species Leucadendron discolor bears green leaves on green stems. In addition, whereas ‘Hawaii Magic’ grows to 65 cm in height and 50 cm in width, Leucadendron discolor grows to 2 m to 2.5 m in height and 1.5 m in width.

‘Hawaii Magic’ differs from Leucadendron salignum var. ‘Red Devil’ by foliage color and plant size. Whereas ‘Hawaii Magic’ exhibits leaf colors which range from green to plum, the leaves of Leucadendron salignum var. ‘Red Devil’ are yellow and red in color. In addition, whereas ‘Hawaii Magic’ grows to 65 cm in height and 50 cm in width, Leucadendron salignum var. ‘Red Devil’ grows to 1.0 m to 1.5 m in height and 1 m in width.

‘Hawaii Magic’ may also be compared with the Leucadendron variety in commerce known as ‘Safari Sunset’ (unpatented).
