Abstract

A new and distinct cultivar of Agastache plant named ‘ASURO08-0’ is disclosed, characterized by unique rose flowers, and increased branching. Plants are vigorous and produce densely flowering verticillasters. The new cultivar is an Agastache, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Agastache hybrid.

Variety denomination: ‘ASURO08-0’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of a planned breeding program by the inventor. An open-pollination of multiple unnamed, unpatented, proprietary varieties of Agastache was made in August 2018 in Santa Paula, Calif. Seed was bulk collected and planted for out in trial conditions. ‘ASURO08-0’ was found and selected in April 2019 in the group of plants resulting from the above open-pollination.

The first asexual propagation of ‘ASURO08-0’ occurred in April 2019 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 rose-colored flowers.
- 2. Increased branching.
- 3. Densely flowering verticillaster.
- 4. Vigorous plants.

COMPARISON TO PARENT VARIETIES

The exact parentage of ‘ASURO08-0’ cannot be determined as an open-pollination involving multiple parents was made and seed bulk collected.

COMMERCIAL COMPARISON

‘ASURO08-0’ can be compared to the commercial variety Agastache ‘Acapulco Rose’, unpatented. Plants of the two cultivars are similar in most horticultural characteristics. Plants of the new cultivar ‘ASURO08-0’, however, differ in the following:

- 1. The new variety produces more branches than this comparator.
- 2. The new variety produces more inflorescences than this comparator.
- 3. Flowers of the new variety are stacked more tightly on the verticillaster than flowers of this comparator.
- 4. The new variety is overall more floriferous than this comparator, having more inflorescences, and denser inflorescences with more flowers.

‘ASURO08-0’ can be compared to the commercial variety Agastache ‘ASUBL01-0’, U.S. Plant Pat. No. 32,376. Plants of the two cultivars are similar in most horticultural characteristics. Plants of the new cultivar ‘ASURO08-0’, however, differ in the following:

- 1. The new variety produces rose-colored flowers; this comparator produces violet colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

‘ASURO08-0’ 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 6 months old from a rooted cutting grown in a greenhouse in Santa Paula, Calif. during Spring.
