Daylily Cultivar with Extended Blooming via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Daylily cultivars have short blooming seasons, typically lasting less than 30 days, and produce fewer fans and scapes compared to 'Dynamite Returns', which offers a long and continuous blooming period and higher bud production.
Innovation Solution
The 'Dynamite Returns' cultivar, resulting from crossing 'Romantic Returns' and 'Red Hot Returns', exhibits semi-evergreen characteristics, producing attractive ruffled bright rosy pink flowers with a long blooming season, multiple fans, and high bud count, outperforming similar cultivars like 'Stella D' Oro' and 'Happy Returns' in terms of duration and intensity of blooming and foliage production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional Daylily cultivars are used, then the plant structure is simple and easy to cultivate, but the blooming season is short (less than 30 days) and bud production is limited
Solution Approach 1:
The plant is divided into multiple functional components: multiple fans per plant, multiple scapes per fan, and multiple buds per scape. This segmentation allows the plant to produce flowers continuously across different modules throughout the season, extending the overall blooming duration from less than 30 days to up to 90 days while maintaining individual simplicity of each unit.
Solution Approach 2:
The plant exhibits periodic blooming cycles with repeat blooming capability, where fans and scapes develop in successive waves throughout the growing season. This periodic production of flower-bearing structures enables continuous blooming for up to 90 days, transforming the single-bloom pattern into a sustained periodic flowering system.
2Productivity
If conventional Daylily cultivars are used, then the cultivation process is simple, but the number of fans and scapes produced is low
Solution Approach 1:
Multiple fans are combined into a single plant structure, and multiple scapes are combined on each fan. This merging of multiple productive units (fans and scapes) into one plant increases overall productivity significantly, producing up to 6 or more fans per year with several scapes per fan, compared to the typical 2-3 fans with one scape per fan in conventional cultivars.
3Quantity of substance
If conventional Daylily cultivars are used, then the plant requires minimal care, but the bud count per scape is limited
Solution Approach 1:
The plant architecture transitions from a single-dimension structure (one scape per fan) to a multi-dimensional structure with multiple scapes per fan and multiple buds per scape. This dimensional expansion in the flowering structure allows the plant to produce in excess of 30 buds per scape and multiple scapes per fan, dramatically increasing the total bud count without proportionally increasing care requirements.

AI summary
A new and distinct Hemerocallis cultivar of the semi-evergreen type is provided. The new cultivar is very floriferous and forms attractive ruffled bright rosy pink flowers displaying substantial substance, and a funnel-shaped form over an extended period of time. In U.S.D.A. Hardiness Zone No. 6, blooming commonly begins during late June and commonly ends during mid-September. The new cultivar displays a plurality of fans and a plurality of scapes per fan. In excess of 30 buds commonly are formed per scape. The new cultivar is well suited for growing as distinctive colorful ornamentation in the landscape.
