Hydrangea Black Steel Blue, Large 5 Litre Plants. A relatively new introduction that produces the much-loved flower clusters throughout summer and autumn, what makes Black Steel Hydrangea stand out from the crowd is the thick shiny black stems. This gives the plants a lovely contrasting look, black stems, dark green foliage and beautiful blue flowers. Colour of the flowers can vary depending on soil type, however to keep your flowers blue all you need to do is add Sulphate of Iron at soil level in Autumn, this will raise acid and lower lime. 

What to expect: Hydrangea plants can vary in size depending on the time of year purchased, however it will arrive in a 5 litre pot with a height upto 60cm excluding the pot, the current pictures were taken in August 2017, flower are not fully emerged. 

Leave the old flower heads in place through the winter. Do not be tempted to cut back until after the worst of the weather has passed. As the new shoots start to emerge in spring cut back a third to a quarter of the previous seasons flowering stems.
