Flowering crab apple tree named ‘Uebo’

Abstract

A new and distinct Malus mill. plant having a weeping, dense habit and persistent fruit.

Description

Botanical classification: Malus mill.

Varietal denomination: ‘Uebo’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of flowering crab apple tree botanically classified as Malus mill. and known by the varietal name ‘Uebo’. The new variety was discovered in 1998 as a weeping, dwarf crab apple seedling of unknown parentage in Vlastiborice Village near Turnov, Czech Republic. The following characteristics distinguish the new variety from other Malus mill. Varieties known to the inventor.

• • Dwarf growth
  • Small tree size
  • Weeping, dense habit
  • Thin shoots
  • Fine branches
  • Fine narrow leaves
  • White flowers
  • Strong annual blooming
  • Fruit persistent into winter
  • Small, bright carmine red fruit

Table 1 compares the new variety to ‘Red Swan’ (U.S. Plant Pat. No. 6,974):

Excellent weeping habit          ‘UEBO’ has a dwarf growth habit,
                                 small-sized tree
Fine, narrow leaves colored gold in ‘UEBO’ has snow white flowers

The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new cultivar, with the color being as nearly true as is possible with color illustrations of this type:

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions by grafting and budding on apple rootstocks first carried out near Turnov, Czech Republic in the spring of 1998. Plants were grown in free soil under field conditions having a mean year temperature of 7.7° C. and a mean precipitation amount of 680 mm/year. The following fertilizer combination was used (kg/ha/year): 55 parts nitrogen, 25 parts phosphorous, 60 parts potassium, 55 parts calcium, and 5 parts magnesium. The color readings were taken in natural daylight. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
