I know nothing at all about plants but have managed to keep my garden going by trial and error! I have a lovely little olive tree outside my front door which never gets any sun and I often forget to water it but it has been very forgiving and lasted 10 years so far!
I'd like to get another small tree or shrub to plant in a pot on the other side of the front door. It's north facing so no direct sun but is inside an open porch so is sheltered from rain and the worst of the winds. An evergreen would be best, something that doesn't need too much TLC and is hard to kill! Any ideas? I did wonder about Holly or a Bay tree?
