USPP30465P3 - Schefflera plant named ‘Monhinschf’ - Google Patents

Abstract

A new and distinct Schefflera cultivar named ‘Monhinschf’ is disclosed, characterized by bright yellow-green petioles on bushy, vigorous plants. ‘Monhinschf’ grows quickly, propagates easily and tolerates cold temperatures. The new variety is a Schefflera taiwaniana, normally produced as an outdoor ornamental garden or container plant.

Description

Latin name of the genus and species: Schefflera taiwaniana.

Variety denomination: ‘Monhinschf’.

BACKGROUND OF THE INVENTION

The new Schefflera cultivar is a product of a breeding program under the direction of the inventor, Rick Wells, at a commercial nursery in Dayton, Oreg. The new variety was selected among a planting of seedlings of Schefflera taiwaniana.

Seed was bulk collect from several plants of an unpatented, unnamed proprietary variety of Schefflera taiwaniana. The new variety was selected among a planting of seedlings resulting from the bulk collected seed in May 2011.

First asexual reproduction of the new cultivar ‘Monhinschf’ was performed by tissue culture at a commercial laboratory in Dayton, Oreg. in May of 2011. Multiple generations and sub-divisions have been produced, and have shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Monhinschf’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Monhinschf’. These characteristics in combination distinguish ‘Monhinschf’ as a new and distinct Schefflera cultivar:

• • 1. Superior branching.
  • 2. Easier to propagate than typical for Schefflera taiwaniana.
  • 3. Faster growth.
  • 4. Better resistance to cold than typical for Schefflera taiwaniana
  • 5. Bright yellow-green petioles.

PARENT COMPARISON

Plants of the new cultivar ‘Monhinschf’ are comparable to the parent Schefflera taiwaniana grown by the inventor. Plants of the new variety are similar in most horticultural characteristics to the parent variety, however, the new variety ‘Monhinschf’ differs in the following:

• • 1. Plants of the new variety have better branching characteristics than the parent.
  • 2. Plants of the new variety have yellow-green petioles, compared to dull green petioles, of the parent variety.
  • 3. Plants of the new variety are more vigorous and grow faster.
  • 4. Plants of the new variety propagate more easily.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘Monhinschf’ are comparable to the variety Schefflera taiwaniana ‘Yuan Shan’, unpatented. The two Schefflera varieties are similar in most horticultural characteristics however, the new variety ‘Monhinschf’ differs having bright yellow-green petioles, whereas petioles of this comparator are green. Additionally plants of ‘Monhinschf’ are faster growing and easier to propagate than plants of ‘Yuan Shan’. Plants of ‘Monhinschf’ also branch better than plants of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

FIG. 1: Illustrates in full color a plant of ‘Monhinschf’ in a 5 gallon pot, approximately 2 years old.

The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
