Buddleia Pink Cascade Hybrid Butterfly Bush Traits

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for a winter-hardy butterfly bush cultivar with a unique combination of traits such as a rounded, arching habit, prolonged flowering season, medium pink flowers, and dark green lanceolate foliage with silvery undersides that is distinct from existing Buddleia cultivars.

Innovation Solution

Buddleia 'Pink Cascade' is a hybrid butterfly bush with a multi-stemmed, well-branched, rounded habit, large, elongated thyrse, and medium pink flowers, developed through asexual propagation from a cross between proprietary hybrids, exhibiting stability across generations and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing Buddleia cultivars are used, then they have established flowering habits, but they lack winter hardiness and unique trait combinations

Engineering Contradiction:

Improvewinter hardinessVSAvoidunique trait combination

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies hybridization to combine traits from two different Buddleia hybrids (12-89-01 and cascading lilac) to create a new cultivar with composite characteristics: winter hardiness from one parent, rounded arching habit from the other, and a unique combination of medium pink flowers with prolonged flowering season. This composite approach resolves the contradiction by integrating multiple desirable traits into a single cultivar that exhibits both reliability and unique adaptability.

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If proprietary hybrids are crossed to create new varieties, then unique trait combinations are achieved, but breeding time and complexity increase

Engineering Contradiction:

Improveunique trait combinationVSAvoidbreeding time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action by conducting extensive preliminary hybridization work and selection processes before the final cultivar is established. The breeder performed multiple generations of hybridization, selection, and evaluation trials to pre-establish the desired trait combination in Buddleia 'Pink Cascade', thereby reducing the time needed for future propagation and commercialization of this specific cultivar.

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If asexual propagation is used to maintain stability, then genotype consistency is preserved, but genetic diversity is reduced

Engineering Contradiction:

Improvegenotype stabilityVSAvoidgenetic diversity

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent uses asexual propagation through stem cuttings to create exact genetic copies of the selected plant, ensuring that the unique genotype of Buddleia 'Pink Cascade' is precisely replicated across multiple plants. This copying approach maintains complete genotype stability while the initial hybridization event had already introduced the desired genetic diversity and unique trait combination into the cultivar.

Inventive Principle:

Principle #26Copying

AI summary

The new and distinct plant of Buddleia ‘Pink Cascade’ is a rounded-mounded, multi-stemmed, winter-hardy butterfly bush with very long, narrow, slightly drooping flowering thyrse producing a waterfall effect over a long season beginning mid-summer with sweetly-fragrant flowers of medium pink petals that are attractively offset by dark green foliage with silvery undersides. The new plant is valuable for landscaping en masse, as an accent or as a potted specimen.
