plant named ‘Sunset Boulevard’

Abstract

A new, distinct Sedum plant as illustrated and described, characterized by large gray-green foliage, RHS 70 A color flowers, and taller height.

Description

Latin name: Sedum hybrid.

Cultivar name: ‘Sunset Boulevard’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Sedum plant named ‘Sunset Boulevard’ characterized by larger gray-green foliage, red-purple color flowers, taller height compared to the seed parent. The new Sedum was raised as a seedling from open pollinated seed sown as an unnamed Sedum ussuriense, not patented, in Hebron, Ill. in 2013. The selection of the new plant was due to its' larger gray-green foliage, deep red-purple color flowers, taller height, compared to the seed parent. Initial asexual reproduction has taken place at a nursery in Hebron, Ill. since 2015 by means of division, and vegetative stem cuttings. The new Sedum has shown to be stable and identical in reproduction to the originally discovered plant after rooting over 1400 plants from 2015 to 2018. No plants of the new Sedum 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 plant named ‘Sunset Boulevard’ characterized by larger gray-green foliage, red-purple color flowers, taller height, compared to the seed parent have been observed to be unique and stable.

Plants of the new Sedum can be compared to plants of Sedum spectabile ‘Brilliant’ not patented. 1. The new Sedum plant has a mature size measuring 50 cm high and up to 70 cm wide while Sedum spectabile measures 45-55 cm high and 55-65 cm wide. 2. The new Sedum has red-purple flowers colored RHS 70 A, while Sedum spectabile is entirely pink.

Plants of the new Sedum can also be compared to the seed parent plant, an unnamed, Sedum ussuriense, not patented. 1. The new Sedum has a mature size of 50 cm high and 70 cm wide while the seed parent has a mature size of 30 cm high and 30 cm wide. 2. The new Sedum has larger foliage measuring on average up to 7 cm long by 4 cm wide while the seed parent has foliage measuring 40 mm long by 35 mm wide. 3. The new Sedum has a stem diameter of 7 mm while the seed parent has stem diameter of 3 mm. 4. The new Sedum has red-purple flowers colored RHS 70 A, compared to the mostly red flowers of the seed parent.
