Title: Weigela plant named ‘TMWG16-02’

Description:
Genus and species:  Weigela florida.    
     Variety denomination: ‘TMWG16-02’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention relates to a new and distinct cultivar of  Weigela , grown as an ornamental plant for use in the garden and landscape. The new variety is known botanically as  Weigela florida  and will be referred to hereinafter by the cultivar name ‘TMWG16-02’. 
     Whereas cultivars of  Weigela florida  in commerce have typically been bred for low compact plant habit, ‘TMWG16-02’ was developed and selected by the inventor for its unique combination of upright plant habit and profuse flowering along the entire stem. 
     ‘TMWG16-02’ arose from an open-pollination in Summer 2014 of the inventor&#39;s proprietary seedling  Weigela florida  ‘WG13001’ (female parent, unreleased and unpatented) in Ipswich, Suffolk, United Kingdom. The identity of the  Weigela florida  male parent is unknown. ‘TMWG16-02’ was selected in 2016 in Ipswich, Suffolk, United Kingdom. ‘TMWG16-02’ was grown at a greenhouse and field nursery in Ipswich, Suffolk, United Kingdom. 
     ‘TMWG16-02’ was first asexually reproduced in Ipswich, Suffolk, United Kingdom in 2016 by softwood cuttings. Since that time, the unique characteristics of the new  Weigela  plant have been uniform, stable and reproduced true to type in successive generations of asexual reproduction via softwood cuttings. 
     SUMMARY 
     The following traits have been repeatedly observed and represent the characteristics of the new  Weigela  variety ‘TMWG16-02’. ‘TMWG16-02’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, however, without any variance in genotype.
         1. ‘TMWG16-02’ exhibits an upright narrow vase-shaped plant habit.   2. After two years of growth in a 3-gallon container, plants of ‘TMWG16-02’ achieve a height of 90 cm to 120 cm and a width (at full height) of 45 cm to 60 cm.   3. A mature plant of ‘TMWG16-02’ which is growing in-ground achieves a height of 180 cm to 200 cm and a width at full height of 90 cm to 120 cm.   4. The flower buds of ‘TMWG16-02’ are pink in color.   5. The flowers of ‘TMWG16-02’ are mid-pink in color when freshly opened.   6. The flowers of ‘TMWG16-02’ become paler pink with age, eventually very pale lilac-pink.   7. The flowers of ‘TMWG16-02’ are borne in clusters along the entire length of the stem.   8. ‘TMWG16-02’ flowers profusely and continuously in early and mid-spring and then sporadically during summer.   9. The foliage of ‘TMWG16-02’ is mid green in color.   10. ‘TMWG16-02’ grows well in moist well-drained soils in full sun to partial shade.   11. ‘TMWG16-02’ is hardy at least to USDA Zone 6.

     Photographs were taken in Oxnard, Calif. from a two-year-old plant which was grown outdoors in a 3-gallon container. No chemicals were used to treat the plant. All photographs were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography. 
     BOTANICAL DESCRIPTION OF THE PLANT 
     The following is a detailed description of the new cultivar ‘TMWG16-02’. Data was collected from two-year old plants grown in 3-gallon containers in Oxnard, Calif.

     COMPARISON WITH PARENTAL LINE 
     In comparison with the female parent, the proprietary seedling  Weigela florida  ‘WG13001’, ‘TMWG16-02’ exhibits a very upright growth and heavy flowering all along its stems. The identity and characteristics of the male parent are unknown. 
     COMPARISON WITH CLOSEST KNOWN VARIETY 
     The closest comparison variety known to the inventor is ‘TMWG16-04’ (U.S. application Ser. No. 16/501,910). Whereas both ‘TMWG16-02’ and ‘TMWG16-04’ exhibit markedly upright plant habits with flowers borne along their entire length of their stems, the flowers of ‘TMWG16-02’ are pink in color, and the flowers of ‘TMWG16-04’ are scarlet in color. In addition, ‘TMWG16-02’ is much earlier to come into flower, typically 4 weeks before the first flowering of ‘TMWG16-04’
