Buddleja Podaras #6 Cultivar Compact Habit Sterile Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Buddleja plants lack compact and sterile varieties with unique and attractive flower coloration, limiting their horticultural appeal and garden performance.
Innovation Solution
A new cultivar, 'Podaras #6', resulting from a planned breeding program between Buddleja davidii and Buddleja alternifolia, exhibits a compact, upright growth habit, sterile light violet flowers, and good garden performance, distinguishing it from parent selections and similar varieties like 'Pink Delight'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Buddleja breeding methods are used, then flower coloration is achieved, but plant size remains large and growth habit is less compact
Solution Approach 1:
The invention applies parameter changes by selecting and breeding for specific growth habit parameters (compactness, density, upright form) while maintaining flower coloration. The cultivar 'Podaras #6' exhibits these changed parameters through controlled cross-pollination and selection, achieving a plant height of about 28 cm and a compact upright habit that differs from traditional Buddleja varieties.
2Reliability
If fertile Buddleja varieties are bred, then seed production is possible, but flower coloration stability and garden performance are compromised
Solution Approach 1:
The invention extracts the reproductive function from the plant by producing sterile cultivars that cannot produce seeds. This is achieved through controlled cross-pollination between Buddleja davidii and Buddleja alternifolia selections, resulting in hybrid plants with stable flower coloration but reduced fertility. The sterile nature eliminates seed production while maintaining vibrant flower colors and reliable garden performance.
3Quantity of substance
If dense growth habit is achieved, then plant compactness is improved, but light penetration and air circulation may be reduced
Solution Approach 1:
The invention applies dynamics by creating a plant with an upright and outwardly spreading habit that allows for dynamic light penetration and air circulation despite dense foliage. The compact growth form with proper branching architecture enables light to reach lower leaves while maintaining high foliage density for aesthetic appeal and garden performance.
