Abstract
A variety of ornamental cherry that combines a strongly upright branch habit, a narrow form, and deep pink flowers.
Description
Latin name of the genus and species of the plant claimed and variety denomination: Prunus sargentii ‘JFS KW21PS’.
In 1989, I began a program to select improved cultivars of Prunus sargentii as ornamental cherry trees. In May of 1989, I planted 264 open pollinated seedlings of Prunus sargentii in a nursery row in Boring, Oreg. As these seedling trees grew, I marked and selected those with the best foliage and form, and in the March 1992, I selected and numbered the best 24 trees to be transplanted to wider spacing in the same nursery and destroyed the remaining trees. Of these trees, the one that I numbered as ‘03’ proved to have an excellent characteristics of a broadly vase shaped form, bright fall color, and late foliage emergence, but its flowers were only typical of the species. I chose not to introduce ‘03’, but instead, I collected its open pollinated seed in the fall of 2002 to grow for future selection. Of the other 23 transplanted trees, I destroyed 22 and eventually introduced one as the cultivar ‘JFS-KW58,’ not patented.
In the fall of 2002, I planted the open pollinated seed of ‘03’ into a bed in a Boring, Oreg. nursery, then grew the seedlings for two seasons. In the March 2005, I transplanted the 24 small trees grown from ‘03’ seed and grew them in a Boring, Oreg. nursery for four seasons, marking and recording their characteristics. In the fall of 2008, I decided that only one tree was of high enough quality to warrant potential introduction, so I destroyed the other 23. I was first attracted to this particular tree because of its flowers which were large and brighter and deeper pink than any other Prunus sargentii seedling that I had seen. In February of 2010, I named this tree ‘JFS KW21PS’ and transplanted it to wider spacing for further evaluation.
In 2014, 2015, 2016, and 2017, I directed test propagation of a total of 35 trees by budding in a Canby, Oreg. nursery and a total of 41 trees by budding in a Boring, Oreg. nursery onto Prunus avium rootstock. I also directed test propagation of 65 trees by softwood cutting in 2015. Of these test propagated trees, 25 have been retained for stock increase in a nursery stock block in Boring Oreg. and the rest were destroyed. From all this propagation, I determined that the characteristics of my new variety were firmly fixed and all propagated plants have been identical to my new variety in every way observed.
This new cultivar possesses a unique combination of characteristics in that it combines prolific production of unusually bright, deep pink flowers with a narrow inverted cone shaped form.
The colors of an illustration of this type may vary with lighting conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.
