Phlox Cultivar Perfectly Puzzling Starry Petal Morphology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Phlox cultivars lack unique flower colors, plant habits, and adaptability to specific garden conditions in the upper Midwest climate, particularly in U.S.D.A. Zone 5, and do not exhibit the desired ornamental traits such as non-overlapping, notched petals and flower fragrance.
Innovation Solution
The development of the Phlox hybrid cultivar 'Perfectly Puzzling' with flowers varying in color from near white to light to medium raspberry violet, featuring non-overlapping, notched, and narrow petals with violet striae, providing a 'starry' appearance and good adaptability to Zone 5 conditions, achieved through controlled breeding and asexual propagation by shoot tip cuttings.

Engineering Contradiction Analysis
1Shape
If traditional Phlox cultivars are used, then the plant is easy to grow and maintain, but the flower colors are lack of uniqueness and the petals do not exhibit the desired non-overlapping, notched appearance
Solution Approach 1:
The patent applies parameter changes by selectively breeding Phlox plants to achieve specific petal shape parameters (non-overlapping, notched appearance) and color parameters (raspberry violet to white gradient). The breeder modified the genetic parameters of the plant over multiple generations to produce the desired cultivar characteristics while maintaining overall plant health and ease of cultivation.
2Shape
If Phlox cultivars with unique flower colors and starry appearance are developed, then ornamental traits are improved, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The breeding program was segmented into manageable phases: selecting parent plants with desired traits, controlled pollination, seedling evaluation, and cultivar development. This segmentation allowed the breeder to focus on specific traits (petal shape, color patterns, fragrance) systematically rather than attempting to improve all characteristics simultaneously, reducing the overall complexity of the breeding process.
3Reliability
If the Phlox cultivar is adapted to upper Midwest climate conditions, then hardiness is improved, but the plant may lose some of the delicate ornamental characteristics
Solution Approach 1:
The cultivar was bred to achieve universality by incorporating traits that function in both ornamental and survival contexts. The non-overlapping petal structure provides both aesthetic appeal and improved air circulation for disease resistance. The raspberry violet to white color gradient provides visual attraction while the underlying plant architecture maintains cold hardiness for upper Midwest climates, allowing the same structural features to serve multiple purposes.

AI summary
A new cultivar of Phlox plant named, ‘Perfectly Puzzling’, that is characterized by its flowers that vary in color from near white to light to medium raspberry violet; the different color flowers can be evident on a plant at the same time, its petals that are non-overlapping, notched (bifid) and narrow resulting in a “starry” appearance that is unusual for a moss Phlox, its petals with medium to dark violet striae at the base, and its flowers that are smaller in size than most moss Phlox, however the flowers still cover the plants 100% at peak bloom.
