Seal them in an envelope and store somewhere dry and cool, sow in seed and cutting compost in trays early spring indoors on a windowsill, pot on as they grow, plant out when risk of frost is over, see here

In a nutshell Bamboo. You make it sound so simple.

You haven't put your county on your profile so I don't know if this is helpful or not - but here is West Wales they self seed and pop up all over the place and you could sow them outside now. If you get harder winters than we do you can't go wrong with the above advice.
