AI Technical Summary
There is a need for a new and distinct cultivar of Meadow Rue (Thalictrum) that exhibits unique foliage and flower characteristics, such as tripinnately compound medium green leaves and wispy lavender flowers, while also being winter-hardy and resistant to common pests and diseases, which existing cultivars like 'Nimbus Pink', 'Black Stockings', and 'Ghent Ebony' do not provide.
The cultivar 'Cotton Candy' is a hybrid of Thalictrum aquilegiifolium 'Nimbus White' and T. polygamum 'A', developed through asexual propagation by sterile plant tissue culture, exhibiting distinctive traits including medium green foliage, lavender flowers, and dark stems, with resistance to browsing by Odocoileus virginianus and Sylvilagus.
The cultivar 'Cotton Candy' maintains stability and identity through multiple generations, offering a unique combination of foliage and flower characteristics, winter hardiness, and pest resistance, distinguishing it from existing cultivars.
