Sedum plant named ‘Class Act’

Abstract

A new and distinct hybrid of Sedum plant substantially as shown and described, with deep red purple flowers with prominent cream colored bud, green leaves edged red, and a short, stiff upright habit.

Description

Botanical denomination: Sedum spp.

Variety Designation: ‘Class Act’.

Parentage: S. spectabile ‘Brilliant’×S. telephium dark leaf.

Compared with Sedum ‘Mr. Goodbud’ (U.S. Plant Pat. No. 17671).

The present invention relates to a new and distinct cultivar of Sedum and given the cultivar name of ‘Class Act’. Sedum is in the family Crassulaceae. Sedum ‘Class Act’ originated from an open pollinated cross between Sedum spectabile, ‘Brilliant’, unpatented, as the seed parent and an unknown and unpatented dark leaf Sedum telephium as the pollen parent.

This new and unique Sedum is distinguished by:

• • 1. Large dark red purple flowers.
  • 2. Cream colored buds.
  • 3. Dark leaf margins.
  • 4. Short stature.
  • 5. Stiff, upright habit.

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 DRAWING

COMPARISON TO SIMILAR SEDUM

Compared to Sedum spectabile ‘Brilliant’, the unpatented seed parent, Sedum ‘Class Act’ is shorter, more stiffly upright, with darker leaves and leaf margins. The leaves are held more upright on the stem and the flowers are of a duller color. Compared to Sedum telephium, ‘Atropurpureum’ and other dark leaf forms, Sedum ‘Class Act’ has greener leaves, lighter stems, and showier flowers.

Compared to Sedum ‘Mr. Goodbud’ (U.S. Plant Pat. No. 17671), the new variety has a slightly taller and narrower habit, a later bloom time, and a deeper red purple flower color.
