Conrad RichterA Half Century of Herbs, Conrad Richter      

When the founders of Richters, Otto and Waltraut Richter, started growing herbs for personal use in the 1960s, they never expected anyone to take an interest in the odd-looking plants growing in a corner of a greenhouse filled with flowering geraniums, petunias and marigolds for sale. But people did notice those strange plants and started to ask about them. Not knowing the English names, Waltraut would try to explain how to use the herbs just as her mother used them back home in Germany. And so a seed sprouted and grew into what Richters Herbs is today.

For our 10th annual Barker Lecture, second generation owner, Conrad Richter, will recount the stories of the many herbs first introduced to Canadian gardeners through the Richters catalogue. A few lucky attendees of tonight's gathering will have the opportunity to go home with some of the herbs featured in this presentation.

Conrad Richter, President of Richters Herbs ( is a Botanist and leader in herbal research and development. Through his efforts, many herbal discoveries and plants of international origin are now available to North American gardeners.
