Kathrine,
For seven years there is a sale from plants in the Botanic Garden. Here there are most different plants. Rock garden plants like Primula, Saxifraga, etc. no Eritrichium! , Hosta, rarer vegetable and herb sorts, Tomatoes, balcony plants, old fruit tree sorts, roses etc. It is a nice show from different nurseries of Austria and Germany. The plants are not cheap. I bought only once one plant.
A Ranunculus without ID.
