I have a rowan, a mimosa, and an autumn flowering cherry all in a line (short wide garden and I'm using these for screening).
I have a gap to fill and can't decide what to put in it. Pear? Crabapple? Plum? Something else? I don't have the patience to buy a pine/yew/spruce and wait for it to grow. And I don't want a cypress type conifer.
I think it's probably too windy for a magnolia, otherwise open to ideas!
