Paeonia ‘Smithopus8’ Triploid Hybrid With Strong Stems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peony cultivars lack strong stems, large panicles, compact habits, and attractive foliage with stable, attractive flower forms, and are often not disease-resistant, making them less suitable for landscape use.
Innovation Solution
Development of the Paeonia hybrid cultivar 'Smithopus8', which is a sterile, triploid intersectional hybrid with semi-woody stems, large, semi-double to double pale yellow flowers, and attractive dissected foliage, offering disease resistance and a compact growth habit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing peony cultivars are used, then they can be grown in landscape, but they lack strong stems and compact habits
Solution Approach 1:
The patent applies parameter changes by creating a triploid (3n) sterile hybrid peony cultivar with modified chromosomal composition. This genetic parameter change results in stronger, semi-woody stems and a more compact growth habit compared to diploid herbaceous peonies, while maintaining landscape suitability through controlled flower production and foliage characteristics.
2Quantity of substance
If existing peony cultivars are used, then they can provide flowers, but they lack large panicles and attractive foliage
Solution Approach 1:
The patent applies local quality by developing a cultivar with differentiated characteristics: the foliage is dissected and attractive for landscape use, while the flower panicles are large and prominent. The plant habit is compact and controlled, with flowers positioned above and beyond the foliage, creating localized areas of high visual impact without excessive overall plant size.
3Reliability
If existing peony cultivars are used, then they can be grown, but they are not disease resistant
Solution Approach 1:
The patent applies the intermediary principle by using a controlled cross between specific parent cultivars ('Martha W' and 'Smith's Yellow') that are known to possess disease resistance traits. The triploid sterile hybrid acts as an intermediary that combines and stabilizes these resistance characteristics while producing the desired flower traits, creating a reliable landscape plant.
4Stability of the object's composition
If sterile triploid hybrids are created, then flower form stability is improved, but fertility is lost
Solution Approach 1:
The patent applies the blessing in disguise principle by accepting and utilizing the sterility of the triploid hybrid as a beneficial characteristic. The sterile first-generation hybrid produces stable, true-to-type flower forms and foliage that remain consistent across generations, which is precisely what is needed for reliable landscape planting. The sterility prevents unwanted seed production while maintaining the desired horticultural characteristics.

AI summary
A new and distinct cultivar of intersectional hybrid (Itoh) Paeonia plant named ‘Smithopus3’ is disclosed, large pale yellow flowers flushed pink with a distinctive red basal flare of semi-double to fully double form carried on strong stems, which present the flowers above and beyond the foliage. Plants have very attractive, dissected foliage, which lasts through the fall and is also highly disease resistant. Plants have a symmetrical, compact plant habit/shape which is excellent in the landscape. The new variety is a intersectional hybrid (Itoh) Paeonia normally produced as an outdoor ornamental garden plant.
