Hydrangea macrophylla Horwack PP25,577

 
 
 
 
 

Hydrangea macrophylla ‘Horwack’ is a compact shrub with unusual flower colouring – a great combination of rich chartreuse and pale green. The unique flowers are globular corymbs, blooming from July to August. Very suitable as a pot plant. This plant is another victim of the confusing international trademarking and patenting regulations.

Inflorescence: Mophead, 130mm across. The flowers are green and chartreuse with a pink or blue eye. The less numerous fertile flowers can be found beneath the ray florets and have 8 stamens, 3 club-shaped pistils.
