Annys Dwarf Ilex Cultivar Propagation and Ornamental Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Ilex x meserveae that exhibits unique ornamental characteristics such as compact growth, abundant flowering, and specific foliage and flower traits, which are not met by existing cultivars like 'Blue Prince' and 'Geers'.
Innovation Solution
The 'Annys Dwarf' cultivar, discovered as a chance seedling, is propagated through semi-hardwood stem cuttings and characterized by fine, glossy dark green foliage that turns dark purple-green in winter, compact habit, absence of berry production, and smooth leaf surfaces with soft spines, distinguishing it from other Ilex x meserveae cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Ilex x meserveae cultivars like 'Blue Prince' and 'Geers' are used, then certain ornamental traits are achieved, but the specific combination of compact growth, abundant flowering, and unique foliage characteristics is not met
Solution Approach 1:
The patent creates a true-to-type copy of the desired plant characteristics through asexual propagation. By using semi-hardwood stem cuttings to reproduce the 'Annys Dwarf' cultivar, the invention ensures that all ornamental traits (compact habit, dark green foliage, soft spines, abundant flowering) are exactly replicated in successive generations, achieving both adaptability and reliability
2Stability of the object's composition
If asexual propagation by semi-hardwood stem cuttings is used, then stable and true-to-type characteristics are achieved, but propagation time and effort are required
Solution Approach 1:
The patent performs preliminary action by collecting and storing semi-hardwood stem cuttings during the optimal window in October 2010, before the full propagation process begins. This preparatory step ensures that propagation material is ready when conditions are favorable, reducing overall propagation time while maintaining characteristic stability through controlled asexual reproduction
