plant named ‘Desert Blonde’

Abstract

A new and distinct hybrid of Sedum plant substantially as shown and described, with creamy yellow flowers in large inflorescences, blue green leaves, strong rose pink stems, rust red carpels when the seed is developing, a dense, low, mounding habit, and excellent vigor.

Description

Botanical denomination: Sedum telephium (Syn. Hylotelephium telephium).

Variety designation: ‘Desert Blonde’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum telephium and given the cultivar name of ‘Desert Blonde’. Sedum is in the family Crassulaceae. The new cultivar is part of a planned breeding program to make short, compact, multicrown plants. The new cultivar originated from an open pollinated cross of a proprietary seedling, Sedum 19-1.

Compared to the seed parent, Sedum 19-1, the new cultivar, has a much better habit and creamy yellow flowers rather than light pink.

Compared to Sedum ‘Yellow Xenox’, U.S. Plant Pat. No. 21,528, the new variety is has creamy yellow flower buds rather than pink, a wider habit, with more crowns from young plants (an advantage to a nursery grower as the plants fill the pots quickly).

SUMMARY OF THE INVENTION

This new and unique Sedum is distinguished by:

• • 1. creamy yellow flowers in large inflorescences,
  • 2. blue green leaves,
  • 3. strong rose pink stems,
  • 4. rust red carpels when the seed is developing,
  • 5. a dense, low, mounding habit, and
  • 6. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, 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.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows the foliage of a two-year-old Sedum ‘Desert Blonde’ growing in the garden in mid-June in Canby, Oreg.

FIG. 2 shows one-year-old plants of Sedum ‘Desert Blonde’ in bloom in the trial field in late August in Canby, Oreg. The fruits are the rust red seen.
