Azalea RLH1-12P0 Compact Habit Remontant Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Azalea plants lack compact growth habits, consistent remontant flowering across seasons, and adequate temperature tolerance, which limits their garden performance and adaptability.
Innovation Solution
A new cultivar, 'RLH1-12P0', resulting from a cross-pollination between Rhododendron hybrida 'RLH-1800-WS' and 'Watchet', exhibits a compact, spreading habit, dense foliage, remontant flowering, and improved temperature tolerance, characterized by large pink flowers with red-purple spots, and enhanced garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If existing Azalea plants are grown to achieve large flower size, then flower dimensions increase, but plant habit becomes less compact and growth rate decreases
Solution Approach 1:
The patent applies local quality by selecting for specific regional characteristics in different parts of the plant: the cultivar 'RLH1-12P0' exhibits compact overall plant habit while simultaneously producing large flowers, creating differentiated quality distribution where the plant body remains compact but the flowers achieve enhanced size and prominence
2Duration of action of moving object
If existing Azalea plants are bred for single seasonal flowering, then flowering period is concentrated, but remontant flowering consistency across spring, summer and autumn is lost
Solution Approach 1:
The patent implements periodic action through remontant flowering characteristics that enable multiple flowering cycles throughout the year. The cultivar 'RLH1-12P0' produces flowers in spring, summer, and autumn seasons, creating periodic flowering patterns rather than a single concentrated bloom period, thereby achieving consistent recurrent flowering across different seasons
3Ease of manufacture
If existing Azalea plants are selected for ornamental value, then flower attractiveness increases, but temperature tolerance and garden performance decrease
Solution Approach 1:
The patent applies universality by developing a cultivar that performs multiple functions simultaneously: 'RLH1-12P0' provides ornamental value through large attractive pink flowers with red-purple spots, while also demonstrating reliability through excellent temperature tolerance and adaptability to USDA Hardiness Zones 6-9, thereby achieving both aesthetic appeal and environmental resilience in a single plant variety
4Stability of the object's composition
If existing Azalea plants are propagated to maintain genetic purity, then genotype stability is preserved, but phenotypic uniformity under varying environmental conditions deteriorates
Solution Approach 1:
The patent applies parameter changes by selecting for genetic traits that express phenotypic consistency across environmental variations. The cultivar 'RLH1-12P0' maintains uniform phenotype expression for key characteristics including flower color (pink with red-purple spots), plant habit (compact and mounding), and growth rate, demonstrating stable trait expression that compensates for environmental fluctuations while preserving genotype stability

AI summary
A new and distinct cultivar of Azalea plant named ‘RLH1-12P0’, characterized by its compact, upright to outwardly spreading and mounding plant habit; freely basal branching habit; dense and bushy appearance; vigorous growth habit and rapid growth rate; evergreen, persistent dark green-colored leaves that do not abscise during the winter; freely flowering habit with remontant flowering during the spring, summer and autumn; large, non-persistent single flowers that are light pink in color with red purple-colored central spots and speckles; and excellent garden performance and temperature tolerance.
