Let's colour the horizon

Product range

The fundamental basis for good hydrangea varieties is a sum of several factors.

Experience is one such factor, but there is more. These include:

  • An extensive gene database full of plants with every conceivable characteristic.
  • Thorough knowledge of the material and accurate records.
  • Regular feedback from vendors, so knowledge of market needs.
  • Continuous testing of clones and conducting field trials.
  • Back-up of any future varieties to be introduced.
  • Strict selection criteria: no brake dust on seedlings, no branch support, good branching, leaf size and colour, flowering characteristics (shape, colour and fullness), shelf life and susceptibility to powdery mildew. 

This results in the assortment below.
