Leave it to a gardener to complicate the concept of "tea party." Store-bought leaves? Please. You call yourself an obsessed gardener? The tea party isn't real unless the leaves are harvested in your backyard. I know this how? Because yes, I did thank-you-very-much. Easy.
First things. Since Camellia sinensis, the tea plant, dreads the cold (USDA zones under 7 may endure Camellia tantrums that end in death), two words of advice: Go herbal.
Two more words: Lemon verbena.
Why? It’s my favorite. Why? Romantic memory that begins in Paris (where else). Wandering Places des Victoires many years ago, I pushed open the door of a 19th century herbalist shop and left laden with tea bags labeled verveine.

6. Store them. Once dry, put the leaves in plastic bags or a container. Make sure they are completely dry, otherwise they will grow mold. They keep in the cupboard indefinitely.

9. Be a good mum. Before the first frost, bring your plant in and pot it up. Keep it in a dry place where it won’t freeze over the winter. Do not water it while it is dormant. Bring it out after the last frost and you'll soon get the 6 foot bushes that I have. Then start thinking about the herbal tea business you'll start ...
