I'm looking for suggestions for a (very) small tree or mid size shrub (max height just under 2m max) to plant in my small front garden. The aspect is NE and the soil is heavy clay, so not an easy location. Ideally, I would like something with seasonal interest - architectural, blossom, berries, colour but not too high maintenance - so everything! I realise I can't really have it all, not least as It would be planted close to the house. I don't want to block the view from my kitchen window or obviously to cause issues with the foundations.
Currently the area is laid to lawn with a border of ferns/shade loving plants and bulbs which do well, but the grass does not as becomes mossy and weedy every year. After chatting to a landscaper, I've decided to remove the lawn and have gravel and planting instead, possibly with underplanting.
Thanks
