Spiraea Conspiyet Compact Growth Habit and Self-Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Spiraea cultivars lack compact growth habits and abundant inflorescences, with existing varieties often having flowers that do not persist or self-clean effectively, limiting their horticultural appeal.
Innovation Solution
Development of a new Spiraea japonica cultivar 'Conspiyet' with pure white flowers, medium green foliage, and a moderately vigorous, compact, low-mounding growth habit, achieved through open-pollination and asexual reproduction, which reproduces true to type and exhibits improved flower longevity and self-cleaning characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Spiraea cultivars are used, then they have basic growth and flowering, but they lack compact growth habits and abundant inflorescences
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific growth habit parameters (compact, low-mounding form) and inflorescence parameters (abundant, dense clusters). The cultivar 'Conspiyet' exhibits a growth habit that is fundamentally different from conventional Spiraea, with a compact, mounding form rather than upright or spreading habits, and produces abundant inflorescences with 15-25 flower clusters per plant compared to fewer clusters in conventional varieties.
2Duration of action of stationary object
If existing Spiraea varieties are used, then they provide seasonal flowering, but the flowers do not persist or self-clean effectively
Solution Approach 1:
The patent applies self-service through the self-cleaning mechanism where spent flowers and seed heads are naturally shed from the plant without human intervention. The cultivar 'Conspiyet' exhibits effective self-cleaning where dead flower material falls off readily, keeping the plant appearance neat without requiring manual removal. This contrasts with conventional varieties where spent flowers persist and require manual cleaning to maintain aesthetic appearance.
3Shape
If Spiraea 'Anthony Waterer' is used as parent, then it has rosy-pink flowers and low-spreading habit, but the offspring lack pure white flowers and improved flower persistence
Solution Approach 1:
The patent applies universality by combining multiple desirable traits from different sources into a single cultivar. The breeding program selected for pure white flower color (a recessive trait), compact low-mounding growth habit, and abundant inflorescences with improved persistence. The resulting cultivar 'Conspiyet' universally exhibits all these traits simultaneously: pure white flowers, compact habit, abundant flowering, and effective self-cleaning, making it a multi-functional improvement over the parent 'Anthony Waterer' which had rosy-pink flowers and less persistent blooms.
