David Horák (Czech Republic)
Czech breeding of Saxifraga sect. Porphyrion ser. Kabschia (formely Porophyllum)
The lecture is dedicated to Karel Lang

Botanist by education, now actively involved in running one of the Czech oldest plant nurseries. His main gardening and, extensively, also scientific interest is devoted to the genus Saxifraga. But he likes „playing“ with the cultivation of many other alpine plants and conifers and their combinations in planting in rock gardens. He also likes to catch the possibilities for travelling to different mountains and has been honoured to join Vojtech Holubec and Josef Jurasek on their travels.
