Hydrangea ‘Verena’ is one of the most popular hydrangeas for cut flowers for weddings. The large blooms make it ideal for cut flowers and the blooms can be quite costly. In 2006, Jacobus Kolk of the Netherlands found a branch mutation on ‘Verena’ with deep purple-brown, almost black stems. He had this patented and it was brought to the United States through our friends at Concept Plants under the name Onyx™ Flamingo. The dark black stemming on Onyx™ Flamingo is quite attractive making it an even better cut flower than ‘Verena’. The large pink blooms create a dynamic contrast nicely with the black stems. It’s no wonder it was named after a flamingo, as Onyx™ Flamingo stands out in the garden. Onyx™ Flamingo may reach 3-4 ft in height by 2-3 ft in width in 10 years. Onyx™ Flamingo is a hydrangea will enjoy in your garden or in a vase in your home. For me, it’s one I will enjoy constantly taking photos. 

Onyx™ Flamingo may be more pink if the soil is more alkaline and more blue to purple if the soil is more acidic. Onyx™ Flamingo may be turned more blue by using acidic fertilizers. Most prefer Onyx™ Flamingo in the pink color. This can be encouraged by using garden lime.
