Piet has many genera in continual development so that he can get the plants he wants for his garden designs.

In addition to creating new colours and strong plants, Piet feels that the 'drooping' petal habit of Echinacea can give it a bit of a sad look, and one of his aims is to produce flowers with non-drooping petals. 

Echinacea 'Jade' is the result of years of seedling selection to achieve this.
