Title: Dicentra plant named ‘Spring Magic’

Description:
Botanical designation:  Dicentra formosa.    
   Cutlivar denomination: ‘SPRING MAGIC’. 
   BACKGROUND OF THE INVENTION 
   The present invention relates to a new and distinct cultivar of  Dicentra,  botanically known as  Dicentra formosa  and hereinafter referred to by the name ‘Spring Magic’. 
   The new  Dicentra  originated from an open-pollination in Bressingham, Diss, Norfolk, United Kingdom, of an unnamed selection of  Dicentra formosa,  not patented, as the female, or seed, parent with an unknown selection of  Dicentra formosa  as the male, or pollen, parent. The new  Dicentra  was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled outdoor nursery environment in Bressingham, Diss, Norfolk, United Kingdom in April/May, 1998. 
   Asexual reproduction of the new  Dicentra  by cuttings in a controlled greenhouse environment in Bressingham, Diss, Norfolk, United Kingdom since June, 1998, has shown that the unique features of this new  Dicentra  are stable and reproduced true to type in successive generations. 
   SUMMARY OF THE INVENTION 
   Plants of the new  Dicentra  have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype. 
   The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Spring Magic’. These characteristics in combination distinguish ‘Spring Magic’ as a new and distinct cultivar of  Dicentra:  
         1. Upright and rounded plant habit.   2. Freely flowering habit.   3. Light pink-colored flowers.   4. Good garden performance.       

   Plants of the new  Dicentra  differ from plants of the female parent selection in the following characteristics:
         1. Plants of the new  Dicentra  have darker-colored leaves than plants of the female parent selection.   2. Plants of the new  Dicentra  and the female parent selection differ in flower color as plants of the female parent selection have darker pink-colored flowers.       

   Plants of the new  Dicentra  can also be compared to plants of  Dicentra formosa  ‘Bacchanal’, not patented. Plants of the new  Dicentra  and ‘Bacchanal’ differ in the following characteristics:
         1. Plants of the new  Dicentra  have darker-colored leaves than plants of ‘Bacchanal’.   2. Plants of the new  Dicentra  and ‘Bacchanal’ differ in flower color as plants of ‘Bacchanal’ have darker pink-colored flowers.       

   
     BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
     The accompanying colored photographs illustrate the overall appearance of the new Dicentra, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new  Dicentra.    
     The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Spring Magic’ grown in a container. 
     The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Spring Magic’. 
   

   DETAILED BOTANICAL DESCRIPTION 
   The aforementioned photographs and following observations, measurements and values describe plants grown in Lancaster, Pa. under commercial practice during the winter and early spring in a polyethylene-covered greenhouse with day temperatures ranging from 2° C. to 10° C. and night temperatures ranging from 2° C. to 7° C. Plants were two months from planting when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
