plant named ‘Yellowstone’

Abstract

A new, distinct Sedum sexangulare plant as illustrated and described, characterized by larger foliage and golden yellow foliage color in early summer, compared to the smaller chartreuse foliage in early summer of the parent plant.

Description

Latin name: Sedum sexangulare.

Cultivar name: ‘Yellowstone’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct plant of Sedum sexangulare plant named ‘Yellowstone’ characterized by larger foliage and golden yellow foliage color in early summer, compared to the smaller chartreuse foliage in early summer of the parent plant. The new Sedum sexangulare was raised as an open pollinated seedling, of Sedum sexangulare ‘Golddigger’, not patented, in Hebron, Ill. in 2016. The selection of the new plant was due to its' larger foliage and golden yellow foliage in early summer, compared to the smaller chartreuse foliage in early summer of the parent plant. Initial asexual reproduction has taken place at a nursery in Hebron, Ill. since 2017 by means of division, and vegetative cuttings. The new Sedum sexangulare has shown to be stable and identical in reproduction after rooting over 1000 plants from 2017 to 2020. No plants of the new Sedum sexangulare have been sold in this country, or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which was disclosed by the inventor and his company, Intrinsic Perennial Gardens, Inc within one year of filing of this application and was derived directly from the inventor.

SUMMARY OF THE INVENTION

The new Sedum sexangulare plant named ‘Yellowstone’ characterized by larger foliage and golden yellow foliage, RHS color 1 B and C in early summer, compared to the smaller chartreuse foliage in spring of the parent plant have been observed to be unique and stable.

Plants of the new Sedum sexangulare plant named ‘Yellowstone’ can be compared to plants of, the parent Sedum sexangulare plant named ‘Goldddiger’ not patented. 1. The new Sedum sexangulare plant has larger foliage and golden yellow foliage, RHS color 1 B and C in early summer while the parent plant has smaller chartreuse foliage in early summer.

Plants of the new Sedum sexangulare can be compared to Sedum sexangulare ‘Weisse Tatra’, not patented. The new Sedum sexangulare plant has larger golden yellow foliage RHS color 1B and C in early summer while ‘Weisse Tatra’ has a green foliage all year long.

Plants of the new Sedum sexangulare can also be compared to Sedum rupestre ‘Angelina’, not patented. 1. The new Sedum sexangulare plant has smaller golden yellow foliage RHS color 1 B and C while Sedum rupestre ‘Angelina’ has large golden foliage.
