I've been asked to put up 11 window boxes for my old neighbor, she doesn't want to keep buying bedding plants etc year after year so I'm after some advice on bulbs/perennials etc that don't grow too tall or spread too much and at the same time will be easy for her to maintain etc.. Any tips/advice and best places to shop for them greatly appreciated.. Bearing in mind I've got 11 to fill.. ?
Thanks.
