Nice gift idea grandfatherd,
Left to their own devices, they can become a large shrub or small tree, similar in proportions to a holly, but in the confines of a pot, growth will be less vigorous and they can grow quite happily like this for many years.
being a Mediterranean plant it is best suited to a sunny south facing position, although it will also tolerate some shade.
There is nothing like the smell of the freshly crushed leaves on a warm summers day, so much more aromatic than those dried ones sold in shops!
There is a large bush in the sensory garden at a care home that I visit and my dear ol' Mum always recognizes the smell when I crush a leaf under her nose and that smell stays on my hand for the rest of the day.
