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

[0001] Malus Mill.

VARIETAL DENOMINATION

[0002] ‘UEBO’

BACKGROUND OF THE INVENTION

[0003] 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 Tumov, Czech Republic. The following characteristics distinguish the new variety from other Malus Mill. Varieties known to the inventor:

[0004] Dwarf growth

[0005] Small tree size

[0006] Weeping, dense habit

[0007] Thin shoots

[0008] Fine branches

[0009] Fine narrow leaves

[0010] White flowers

[0011] Strong annual blooming

[0012] Fruit persistent into winter

[0013] Small, bright carmine red fruit

[0014] Table 1 compares the new variety to ‘Red Swan’ (U.S. Plant Pat. No. 6,974):

DESCRIPTION OF THE PLANT

[0022] 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 Tumov, 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.
