I always have a problem lately with the name of a very common garden shrub. It's mahonia - and it's taken me a minute or two just now to recall it. I always know it begins with M, though.
With other things - names or words - I usually find that if I stop trying to recall it, the old subconscious gets to work and it will pop up half an hour or so later.
