Donald and Rozanne Waterer
Donald Waterer was educated at Wellington College and was an adept linguist, but it was horticulture that claimed his primary interest from an early age. He was enthused by his family’s heritage of breeding first class hardy hybrid azaleas and rhododendrons, eventually becoming General Manager and Director of the family’s Knaphill Nursery. There he selected and introduced many azalea cultivars.
Rozanne Waterer, a keen gardener like her husband, noticed that one of the hardy geraniums growing in their private garden (in Somerset, England), exhibited stronger growth, larger leaves and flowers similar to ‘Buxton’s Variety’, but twice as large. It flowered non-stop from June until the first hard frosts in November! Being plants people, Donald and Rozanne sought the advice of geranium experts, including Graham Stuart Thomas, who recommended they contact Must Have Perennials™.
The plant was introduced as Geranium Rozanne® (‘Gerwat’), one of the most shining examples of how keen-eyed gardeners can discover the most successful varieties.
Geranium Rozanne® was launched at the Chelsea Flower Show in 2000. Its popularity has grown in Europe and North America, as it has shown versatility to a wide range of soil and climatic conditions, including tolerance to heat. In 2006 it received the RHS Award of Garden Merit. In 2008, the Perennial Plant Association selected Rozanne® as the Perennial Plant of the Year. In 2013, Rozanne® was voted 'Plant of the Centenary' in a competition celebrating 100 years of the RHS Chelsea Flower Show.
Geranium Azure Rush® is a hybrid of Rozanne® discovered at the zu Jeddeloh Pflanzen Nursery in Germany. It features the same traits as its famous parent G. Rozanne®, with 6 cm light blue flowers that bloom from May until frost, but with a more compact, mounding habit.
Geranium Lilac Ice® is yet another hybrid of Rozanne® showing off pale lilac blooms with dark veins.
