plant named ‘Golden Tiara’

Abstract

A new and unique cultivar of Alstroemeria plant named ‘Golden Tiara’, characterized by its large, upwardly to outwardly spreading and mounded plant habit, moderately to rapid growth rate, producing numerous gold-colored flowers with complementing coral-orange throat, suitable for container and garden landscape performance in areas winter hardy to USDA zone 6.

Description

Botanical denomination: Alstroemeria hybrid.

Cultivar designation: ‘Golden Tiara’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first sale of the claimed plant was made on Nov. 15, 2021, by Walters Gardens, Inc. to Plant Delights Nursery, Inc. Subsequently, the plant appeared on Jan. 1, 2022, on the Plant Delights Nursery, Inc. website, and on Feb. 1, 2022, as a photograph and brief description in the Walters Gardens, Inc. website followed by the “Walters Gardens 2022-2023 Catalog” first distributed to customers on Jun. 8, 2022. Walters Gardens, Inc. and Plant Delights Nursery, Inc. both obtained the plant and all information relating thereto, from the inventor. No plants of Alstroemeria ‘Golden Tiara’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor and would therefore be a 35 U.S.C. § 102b exception.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrid, commercially used as a potted and garden-type Alstroemeria, and hereinafter referred to by the name ‘Golden Tiara’.

The new Alstroemeria plant was discovered in March of 2018, as a whole plant mutation in a batch of ‘Koice’ (not patented) at a nursery in Raleigh, N.C. ‘Golden Tiara’ was then propagated by rhizome shoot tip tissue culture in the fall of 2019 and later propagated by division at the same nursery. The new plant passed final evaluation at a whole perennial nursery in Zeeland, Mich. The new plant has also been propagated by tissue culture rhizogenesis with both division and tissue culture asexual propagation methods proving the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of ‘Golden Tiara’ have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

Alstroemeria ‘Golden Tiara’ is distinct from its parent and all other Alstroemeria known to the applicant in the following combined traits:

• • 1. Large, upwardly to outwardly spreading and mounded plant habit;
  • 2. Moderately vigorous to vigorous growth habit and moderate to rapid growth rate;
  • 3. Numerous gold-colored flowers with complementing coral-orange throat;
  • 4. Excellent container and garden performance;
  • 5. Winter hardy to at least USDA zone 6.

Plants of the new Alstroemeria can be compared to plants of the mutation parent, ‘Koice’. Plants of ‘Koice’ have blushing coral-pink and white flowers with darker bar markings. Plants of the new Alstroemeria can be compared to: ‘Zapriyen’ U.S. Plant Pat. No. 34,018 has white flowers with yellow centers and the size is much smaller in habit. ‘Zoe’ U.S. Plant Pat. No. 30,680 has light red-colored flowers with yellow centers, fewer flowers per inflorescence, and the inflorescences are much shorter.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs of the new invention are of a two-year-old plant grown in full-sun trial garden and illustrate the overall appearance of the plant including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Some slight variations of color may occur as a result of lighting quality, intensity, wavelength, direction, or reflection.

FIG. 2 shows a close-up of the flowers and buds.
