I have a raised flower bed built into the ground of my paver patio which is 9 inches wide and 11 inches deep. This flower bed is on the north side of house and gets little sun. Last year I planted the feathery type of coleus in this bed and that got very tall but leggy I guess due to lack of sun. Do you think the mini hostas would work in this area. I saw them last year at nursery but had not considered this idea at that time. Also I would like to companion them in this bed with coleus but not the feathery type but the type with the nicely colored leaves. What do you think?
