Does anyone know anything about gardening?

Amazing! Thanks.

Only thing worth adding is that it spreads fairly freely. Due to the size of the leaves and density it will dominate other plants, so at some point you'll probably want to reign it in. But it's more of a gradual and continuous encroachment so not hard to do.

Also the RHS' description of semi-evergreen is a bit odd. Unless that means that it dies back to a brown patch with a load of root coloured tuber things under decaying leaves.
