I went through a phase where I was obsessed with bamboo and all things Japanese gardening, so I planted three in my smallish garden. Big mistake. One was a fairly compact variety, but the other two weren't and they rampaged out of control very quickly. I would spend ages in amongst them, cutting them back (at any moment expecting to meet an ancient Japanese soldier who hadn't realised the war was over!). DH would dig out large chunks to reduce their size and eventually we did get rid of one, but it was such a task he refused to tackle the others. We sold the house instead
. The house sold again recently and I noticed from the estate agent's online photo of the garden that they had got rid of them - in fact, they had got rid of everything and what was my lovely garden was just a sanitised expanse of grass. Each. To his own I suppose.
