Open Pollination

2. The original plant was an Heirloom from my grandmas greenhouse. Since she gave it to me I've been growing it outside in my garden. It's OP so who knows what might have created since then.

3. I only grow plants that are OP because I don't believe in the proliferation of genetically modified rapeseed.

4. My plants may be OP but my marriage is not!
