USPP22086P3 - Agastache plant named ‘Summer Fiesta’ - Google Patents

Abstract

A new and distinct form of Agastache plant characterized by red flowers, large, dense flower spikes, an upright branching habit, a long bloom time, and excellent vigor.

Description

Botanical denomination: Agastache spp.

Variety designation: ‘Summer Fiesta’.

Parentage: Agastache ‘Raspberry Summer’ (U.S. Plant Pat. No. 20,371)×unknown.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agastache, given the name, ‘Summer Fiesta’. Agastache is in the family Lamiaceae. This new variety is an open pollinated seedling selection out of Agastache ‘Raspberry Summer’ as such the pollen parent is unknown.

Compared to the seed parent, Agastache ‘Raspberry Summer’ (U.S. Plant Pat. No. 20,371), the new cultivar has red rather than red purple flowers.

Compared to Agastache ‘Acapulco Orange’, the new cultivar has redder flowers with longer inflorescences.

This plant exhibits the following characteristics that make it unique:

• • 1. red flowers,
  • 2. large, dense flower spikes,
  • 3. an upright branching habit,
  • 4. a long bloom time, and
  • 5. excellent vigor.

The new variety has been reproduced only by asexual propagation (stem cuttings and micropropagation using apical buds and nodes). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by stem cuttings and micropropagation using apical buds and nodes as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
