You can grow fruit in potted plants on your window sill? You have a much greener thumb than I have! I can barely keep my potted oregano and rosemary alive. And I have a starter kit of kitchen herbs that is now more than a year old because I keep forgetting to set it up. Luckily, the seeds for the cat grass are quite viable even though they're three years old. Oh, the expired stuff in my home! Don't look at what my "best by" date would be; i think I passed it before I turned 50 ))
