Breeding Hemerocallis had become an addiction for Liselotte, and finding out that very few Hemerocallis were available to Swiss gardeners in 1990, she was determined to change that.Because of the short season, cool summers and winters with 5 - 6 months of snow cover, growing and breeding Hemerocallis is quite difficult. However, her goal is to create vigorous, garden worthy plants that will perform well in a continental climate and at high altitudes.

From working with Hemerocallis , this obsession with pollen spread to Iris and Paeonia. Not having enough time, and the short season with occasional very late frosts in spring and again early frosts in the fall, prevented Liselotte from working with Hosta. Nevertheless, seeds from other sources are started every spring.

New Plants are imported every year and the Hosta collection has grown to over 300. Plants are tested for several years. Some are difficult to grow while others perform beautifully after a somewhat slow start. Because with a few exceptions, all Hosta come from tissue culture, exciting sports appear from time to time.
