Description

Latin name of the genus and species: Agastache hybrid.

Variety denomination: ‘ASUBL01-0’.

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. ‘ASUBL01-0’ was found and selected in August 2017.

The first asexual propagation of ‘ASUBL01-0’ occured 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. Unique violet flowers.
    • 2. Increased branching.
    • 3. Densely flowering raceme.
    • 4. Vigorous plants.

COMPARISON TO PARENT VARIETIES

‘ASUBL01-0’ is similar in most horticultural characteristics to the seed parent. Plants of the new cultivar ‘ASUBL01-0’ however differ in the following:

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

‘ASUBL01-0’ is similar in most horticultural characteristics to the pollen parent. Plants of the new cultivar ‘ASUBL01-0’ 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 violet flowers than the pollen parent.

COMMERCIAL COMPARISON

‘ASUBL01-0’ can be compared to the commercial variety Agastache ‘Acapulco Blue’, unpatented. Plants of the two cultivars are similar in most horticultural characteristics. Plants of the new cultivar ‘ASUBL01-0’, however, differ in the following:

    • 1. The new variety has deeper violet flowers than this comparator.
    • 2. The new variety is a more vigorous plant 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

‘ASUBL01-0’ 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.

FIG. 1 shows a plant of the new variety at about 8 months old from a rooted cutting grown in a greenhouse in Santa Paula, Calif. during Spring.

FIG. 2 shows a close-up view of the inflorescence.
