Hemerocallis ‘G221407’ Cultivar for Continuous Blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hemerocallis cultivars lack distinct floral characteristics, growth vigor, and efficiency in division production, with limited continuous blooming and fragrance, making them less competitive in the market.
Innovation Solution
The introduction of the Hemerocallis cultivar 'G221407', which features apricot-orange flowers with a dark orange-red eye, slight petal ruffling, and high division yield, along with continuous blooming and improved growth rate, addresses these shortcomings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Hemerocallis cultivars are used, then they have basic floral characteristics, but they lack distinct floral features, growth vigor, and division production efficiency
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters including apricot-orange flower color, dark orange-red eye, slight petal ruffling, and enhanced growth rate. These parameter changes distinguish 'G221407' from conventional cultivars and improve both productivity and floral distinctiveness simultaneously
2Duration of action of moving object
If Hemerocallis cultivars are bred for continuous blooming, then blooming duration is extended, but growth vigor and division yield may be compromised
Solution Approach 1:
The patent implements continuity of useful action through continuous blooming from early June until hard frost in autumn. The cultivar 'G221407' maintains this continuous blooming action while simultaneously achieving high division yield of 1.5 to 2 times that of 'Stella D'Oro', resolving the contradiction between blooming duration and productivity
3Speed
If Hemerocallis cultivars are selected for rapid growth, then they fill containers and landscapes quickly, but floral distinctiveness and fragrance may be reduced
Solution Approach 1:
The patent uses parameter changes to achieve rapid growth while maintaining distinct floral characteristics. The cultivar exhibits accelerated growth rate that exceeds most comparable daylilies and produces 1.5 to 2 times the quantity of root divisions, while simultaneously displaying apricot-orange flowers with dark orange-red eye and slight ruffled edges
Solution Approach 2:
The patent combines multiple desirable traits into a composite cultivar that integrates rapid growth, continuous blooming, high division yield, and distinct floral features including apricot-orange color, dark eye, and ruffled edges. This composite approach resolves the contradiction between growth speed and floral quality

AI summary
A new and distinct cultivar of Hemerocallis plant named ‘G221407’ is disclosed, characterized by flowers of an apricot-orange color, with a yellow throat, a darker orange-red eye and a slight ruffle to the petal edge. ‘G221407’ is a diploid, dormant type daylily, losing foliage with frost each fall, and re-emerging from the crown in the following spring. ‘G221407’ grows quickly and vigorously following emergence from dormancy, showing a growth rate during bare-root production which exceeds most comparable daylilies. ‘G221407’ blooms continuously from first-flower in early June until hard frost in the autumn. Plants are observed winter-hardy through at least USDA Zone 5. The new variety is a Hemerocallis, normally used for outdoor ornamental purposes.
