Solution Overview

Problem

Existing Buddleja cultivars lack compact varieties with pendulous habits suitable for hanging baskets and containers, and they do not exhibit diverse flower colors or color combinations.

Innovation Solution

Development of a new Buddleja cultivar, 'SFF22-062', with a pendulous growth habit, intense lustrous rose-pink flowers, and yellow-orange eyes, suitable for hanging baskets and containers, through selective breeding and asexual propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If existing Buddleja cultivars are used, then they can be grown in landscapes, but they lack compact pendulous habits suitable for hanging baskets and containers

Engineering Contradiction:

Improvegrowth habitVSAvoidsuitability for hanging baskets and containers

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by selectively breeding Buddleja plants to modify key growth parameters including internode length (shorter internodes for compactness), stem architecture (arching habit for pendulous appearance), and overall plant dimensions (30 cm height, 90 cm diameter). These parameter modifications create a cultivar specifically adapted for container and hanging basket cultivation while maintaining landscape suitability.

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If existing Buddleja cultivars are used, then they can provide flowering, but they do not exhibit diverse flower colors or color combinations

Engineering Contradiction:

Improveflower productionVSAvoidflower color diversity

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by developing distinct color variations in specific parts of the plant, particularly the flower corollas. The cultivar exhibits intense lustrous rose-pink coloration in the petals with contrasting yellow-orange eyes (central corolla tube), creating localized color zones that enhance visual appeal. This approach allows diverse color expressions while maintaining reliable flowering production.

Inventive Principle:

Principle #3Local quality

3Volume of moving object

If Buddleja plants are bred for compact size, then they are suitable for containers, but they may have reduced flowering capacity

Engineering Contradiction:

Improveplant sizeVSAvoidflowering capacity

Core Design Contradiction:

Volume of moving objectVSProductivity

Solution Approach 1:

The patent applies dynamics by creating a cultivar that rapidly fills container spaces (30 cm height, 90 cm diameter in first season) while simultaneously producing abundant flowers (approximately 300 outward-facing flowers per inflorescence). The plant dynamically adapts its growth pattern to maximize both compact form and flowering capacity, with stems arching downward when laden with flowers, demonstrating the ability to maintain productivity within confined spaces.

AI summary

A new cultivar of Buddleja named ‘SFF22-062’ that is distinguishable by its compact pendulous growth habit suitable for use in hanging baskets, with approximately 300 outward-facing flowers, with flowers having intense non-fading pink color and yellow-orange eyes due to that coloration within the central corolla tube and on the petal bases, is disclosed.
