Description

The present invention comprises a new and distinct cultivar of crabapple tree, botanically known as Malus zumi, and hereinafter referred to by the cultivar name Amberina.

The new cultivar, discovered by the inventor in 1972, resulted from a controlled cross by applicant of seed parent Malus zumi `Christmas Holly` with pollen parent (Malus zumi #243.times.Malus zumi #768), in Medina, Ohio.

Asexual reproduction in the form of softwood cuttings and summer chip budding by applicant in Medina, Ohio has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and are retained through successive generations of asexual reproduction.

Amberina has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, day length, available soil moisture, soil nutrients and p.sup.H level.

The following observations, measurements, and comparisons describe trees grown at Klehm Nursery, Barrington, Ill., under conditions approximating those generally used in commercial practice.

The following repeatedly observed traits and characteristics of Amberina, in combination, distinguish this crabapple tree as a new and distinct cultivar for ornamental and landscape use.

1. Amberina has a strong, upright growth habit, reaching a mature height of about 10 feet.

2. The cultivar's disease resistant, deep green leaves change to bright gold in autumn.

3. Amberina produces bright red berries that maintain themselves on trees for the entire winter.

4. Amberina abundantly flowers as a young tree, producing pink to rose colored buds that open to pure white, flagrant blooms.

5. Amberina roots easily as a soft wood cutting.

Of the many commercial crabapple trees known to the inventor, the most similar in comparison to Amberina is the species Zumi calocarpa. In comparison to Zumi calocarpa cultivars, Amberina has much better winter fruit retention, more abundant blossoms, and foliage that is more resistant to summer diseases.

The accompanying color photographic drawings show typical characteristics of Amberina, with colors being as true as possible with illustrations of this type.

Sheet 1 is a photograph of Amberina in perspective view.

Sheet 2 is a closeup photograph of a branch of Amberina in the bud stage.

Sheet 3 is a photograph of a branch of Amberina, showing buds in varying stages of opening.

Sheet 4 illustrates a branch of Amberina bearing mature fruit.

In the following detailed description of the cultivar, color references are made to The Royal Horticultural Society Colour Chart (R.H.S.).
