The Sustainable Flowers Podcast:

A conversation about sustainable cut flower growing and designing between two passionate Canadian  growers trying to figure it out.

Heather and Clara grow cut flowers for market on the northern edge of the Canadian Prairies.  In this podcast they discuss the issues they face and alternatives to conventional approaches that they are putting into practice or are trialing to ensure that their small-scale flower farming operations are sustainable. Looking to the past and to new technologies to learn the whys and hows, they discuss everything from peat to floral foam, Antirrhinum to Zinnias as well as their weekly adventures on their Zones 2 and 3 flower farms.
