plant named ‘Hinebud3’

Abstract

A Buddleia plant particularly distinguished by low-growing and densely branched, large, pure-white inflorescences that flower soon after propagation, and dark foliage, is disclosed.

Description

Genus and species: Buddleia hybrid (complex hybrid of Buddleia davidii×Buddleia alternifolia×Buddleia caryopterifolia×Buddleia lindleyana×Buddleia crispa).

Variety denomination: ‘Hinebud3’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Buddleia, botanically known as Buddleia hybrid, and hereinafter referred to by the variety name ‘Hinebud3’. The new variety originated from a cross-pollination conducted in Winters, Calif. in August 2010 between the female Buddleia parent, an un-named seedling (unpatented) and the male Buddleia parent, an un-named seedling (unpatented). A single plant selection was subsequently chosen for further evaluation and asexual propagation in Winters, Calif.

The new plant was first asexually propagated in June 2011 in Winters, Calif. and has been asexually reproduced by cuttings for two years in Winters, Calif. The present invention has been found to retain its distinctive characteristics through successive asexual propagations by softwood cuttings.

‘Hinebud3’ has not been made publicly available or sold more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new variety when grown under normal horticultural practices in Winters, Calif.

• • 1. Low-growing and densely branched;
  • 2. Large, pure-white inflorescences that flower soon after propagation; and
  • 3. Dark foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Buddleia plant is illustrated by the accompanying photographs which show the overall plant habit, foliage and inflorescence of the plant. The colors are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 15-month-old plant grown in a greenhouse and outdoors in Winters, Calif. in May 2012.

FIG. 1 shows the whole plant, including the habit, foliage and inflorescence.

FIG. 2 shows a close-up of the inflorescence and foliage.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Hinebud3’. The data which defines these characteristics were collected from asexual reproductions carried out in Winters, Calif. The plant history was taken in May 2012 on two-year old plants grown outdoors in Winters, Calif. Color references were taken under natural light and are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), fifth edition (2007) or to the The R.H.S. mini chart (2005) as indicated. Texture descriptions were taken using a dissecting microscope.
