and here's another that is a week older.
The reason I happened to have a jam jar of water on the windowsill was because I was trying out a system for taking basil cuttings and rooting them in water. While slower than mint the basil went on to develop dramatic roots too:
I will now be potting these up. The basil I have sown at the same time is minuscule so I think this method for generating successional cropping will be very useful for basil.
For mint it just proves how vigorous mint is! If you plant roots it will grow leaves and if you soak leaves/stem it will develop roots!
