I have a liking for cacti. There are a good number around the house and outside. I like their variety of size, shape, colour and flowers. One of my favourites, the Astrophytum, has a flower that when it comes out lasts but a day, but the perfume fills the house. Banknotes too have a variety of shapes, colours and size. Each note in out collections holds a special place and the rarer ones are always good to look at and keep safe. What great interests – Cacti and British Banknotes share a lot in common.
