The flowering dwarfed rhododendron is an alternative to box and was developed by the lime-tolerant rhododendron interest group (INKARHO) of 14 tree nurseries.
Since being introduced to the market in 2015, the dwarf rhododendron, which is a cross of the two wild rhododendron varieties hirsutum and micranthum, has high resistance to box fungus and moths.
The Bloombux balls are sold with a diameter of 30 centimetres in a 5-litre container complete with a stick label. There are also smaller versions of Bloombux, such as 2-litre container or the Nugget by Bloombux for bed framing.
INKARHO managing director Ralf Lüttmann said: "Young garden owners in particular look for plants that offer a combination of visual and ecological benefits. The Bloombux gives young customers looking to add new flair to the gardens what they want."
