USPP14310P3 - Holly plant named ‘Hachfee’ - Google Patents

Abstract

A female holly plant named ‘Hachfee’ having an upright pyramidal growth habit, serrated glossy leaves, glossy red berries, and tolerance to temperatures to −25° C.

Description

Classification: Ilex meservae×aquitolium.

Varietal denomination: ‘Hachfee’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Ilex meservae×aquitolium (holly) known by the varietal name ‘Hachfee’. The new variety was discovered in 1998 in a selected breeding program in Barmstedt, Germany and is a selection from the cross of the unpatented variety of Ilex aquitolium ‘Pyramidalis’ and the Ilex meservae variety ‘Blue Prince’ (U.S. Plant Pat. No. 3,517).

The plant was first asexually reproduced by cuttings in Barmstedt, Germany in October 1997 and has been asexually reproduced by cuttings in Barmstedt, Germany. The distinguishing features of this new cultivar are stable and reproduce true to type in successive propagations.

The following traits are determined to be basic characteristics of this new cultivar which in combination distinguish this variety as new and distinct:

1. Upright, pyramidal habit.

2. Excellent hardiness to −25° C.

3. Typical bluish, green bark.

4. Very glossy leaves, serrated not pricking.

5. Strong grower, at least 50 up to 80 cm per year for the female variety.

The following characteristics distinguish over the new variety from its parents as well as ‘Blue Princess’ (U.S. Plant Pat. No. 3,675) and the unpatented variety ‘Blue Stallion’.

1. Branches grow more upright as a young plant.

2. Faster growing than ‘Blue Princess’.

3. Less trimming required.

4. Forms a close hedge more quickly.

5. Large glossy red berries.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new cultivar, the color being as nearly true as possible with color illustrations of this type. The photographs were taken under natural light conditions in Barmstedt, Germnany.

DESCRIPTION OF THE NEW PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected from asexual reproductions carried out in Barmstedt, Germany. The plant history was taken on a plant about ten years old, grown from a 2 mm rootball. The test plants were grown outdoors at about 8-10° C. nightime temperatures and color readings were taken outdoors.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance were used.
