Bay Tree Laurus Nobilis Ball on Stem 5ft 7 inches high including pot height 50-55cm wide head
Ideal for formal topiary garden, or either side of front door in nice pots.
If you are going on holiday get a neighbour to water them as they can be thirsty.
Other than that, they are much more tolerant of cold than you would think- if lower than -6 degrees C (rare!) then cover with horticultural fleece or stand in the garage over night.
