USPP32334P2 - Agastache plant named ‘ASUOR03-0’ - Google Patents

Abstract

A new and distinct cultivar of Agastache plant named ‘ASUOR03-0’ is disclosed, characterized by orange flowers, good plant vigor, and increased branching. Plants produce densely flowering racemes. The new cultivar is an Agastache, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Agastache hybrid.

Variety denomination: ‘ASUOR03-0’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of a planned breeding program by the inventor. The crossing of two unnamed, unpatented, proprietary varieties of Agastache was made in June 2017 in Santa Paula, Calif. ‘ASUOR03-0’ was found and selected in August 2017.

The first asexual propagation of ‘ASUOR03-0’ occurred in September 2018 by terminal vegetative cuttings at a nursery in Santa Paula, Calif. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in several successive generations.

SUMMARY OF THE INVENTION

The following are the unique combination of characteristics of this new cultivar when grown under standard horticultural practices in Santa Paula, Calif.:

• • 1. Orange flowers.
  • 2. Increased branching.
  • 3. Densely flowering raceme.
  • 4. Vigorous plants.

COMPARISON TO PARENT VARIETIES

‘ASUOR03-0’ is similar in most horticultural characteristics to the seed parent. Plants of the new cultivar ‘ASUOR03-0’ however differ in the following:

• • 1. The new variety has more flowers per inflorescence than the seed parent.
  • 2. The new variety has orange flowers, while the seed parent has pink flowers.

‘ASUOR03-0’ is similar in most horticultural characteristics to the pollen parent. Plants of the new cultivar ‘ASUOR03-0’ however differ in the following:

• • 1. The new variety has greater plant vigor than the pollen parent.
  • 2. The new variety is a denser plant with more branches than the pollen parent.
  • 3. The new variety has darker red flowers than the pollen parent.

COMMERCIAL COMPARISON

‘ASUOR03-0’ can be compared to the commercial variety Agastache ‘Acapulco Orange’, unpatented. Plants of the two cultivars are similar in most horticultural characteristics. Plants of the new cultivar ‘ASUOR03-0’, however, differ in the following:

• • 1. The new variety is a more compact plant than this comparator.
  • 2. The new variety is more floriferous than this comparator.
  • 3. Flowers of the new variety are stacked more tightly on the raceme than flowers of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

‘ASUOR03-0’ is illustrated by the accompanying photographs which show the plant's form, foliage, and inflorescences. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new hybrid Agastache.
