Our Breeders

Must Have Perennials has a long history of teaming up with plant breeders from every background. Perennial varieties come to us from people around the world! This includes professional plant breeders and breeding companies to eagle-eyed growers, and retailers. Similarly, we also receive varieties from amateur gardeners with a passion for plants.

Geranium Rozanne is a shining example, discovered in the private garden of Rozanne and Donald Waterer. Its performance in a wide range of climates around the world, has earned recognition as a PPA Perennial Plant of the Year and also the Royal Horticultural Society’s Plant of the Centenary.  It has also become the single most popular flower on Facebook with over 100,000 followers.

Our Trial Gardens

Must Have Perennials varieties are trialed for years in gardens and pot trials. We conduct trials at secure trial sites, leading perennial growers, universities and botanical gardens worldwide. The trials are comprehensive, establish reliability and provide valuable information on regional performance. These trials are conducted under varying light levels, soil types and overall climatic conditions.
