Hi there, I'm a complete novice gardener and mum of a 4 year old and 1 year old who still wakes at night and returning to work part time so overall energy levels low. But got narrow flower bed in lovely garden that is bare bar weeds. Advice please on what to plant that is hardy as kids likely to chuck ball round it and low maintenance but colourful and will come back each year. Thanks fellow mummies and daddies
