plant named ‘Dynomite’

Abstract

A new and distinct hybrid of Sedum plant substantially as shown and described, characterized by burgundy red flowers in good size inflorescences, leaves with dark leaf margins and red tints, a very dwarf, clumping habit.

Description

Botanical denomination: Sedum hybrid (syn. Hylotelephium).

Variety designation: ‘Dynomite’.

Parentage: Sedum telephium 2-7×Sedum spectabile ‘Neon’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum and given the cultivar name of ‘Dynomite’. Sedum is in the family Crassulaceae. Sedum ‘Dynomite’ originated from a planned breeding program to produce hybrids with dark leaves, short stems and large inflorescences. Sedum ‘Dynomite’ originated from a cross between an unnamed, proprietary, an unpatented Sedum telephium 2-7 as the seed parent and Sedum spectabile ‘Neon’, unpatented, as the pollen parent.

Compared to the seed parent Sedum telephium 2-7, the new cultivar is has larger inflorescences with better flower color, and lighter colored leaves.

Compared to the pollen parent, Sedum spectabile ‘Neon’, the new cultivar, has leaves that have a red leaf edges and red tint in full sun rather than yellow green.

Compared to Sedum ‘Birthday Party’, (U.S. Plant Pat. No. 22,826), the new variety has a smaller and tighter habit and smaller inflorescences.

This new and unique Sedum is distinguished by:

• • 1. burgundy red flowers in good size inflorescences,
  • 2. leaves with dark leaf margins and red tints,
  • 3. a very dwarf, clumping 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.
