All week we've been looking at party manifestos and politicians' pledges on food and farming. We've head from the Conservatives, Labour and the Liberal Democrats - today we round up what the other parties are offering the countryside.

We meet a family of flower growers in Cornwall who've been farming in the Tamar Valley for half a century. Barry Richards built his first glasshouses in the 1970s before the flower market became dominated by imports which pushed many British flower growers out of business. However the Richards have diversified to become importers and distributors. They've massively increased the number of varieties they produce and now grow all year round.

This year's wet weather means farmers are seeing hemlock in places they wouldn't usually see the plant. It's extremely poisonous for animals and people. Agronomists say it's highly unlikely it will get into the food chain, but say farmers need to be vigilant.
