Since we're limited to certain types of actions with our glitchen, wouldn't it be lovely to be able to express ourselves to others with flowers, using a similar (yet simplified) code to that which was used in Victorian times? Perhaps just a few basic ones, like different-coloured roses and such, but it would be so nice to be able to send little messages and tokens to one another. We could grow them ourselves in either herb or veggie plots, and give single flowers or bouquets.
