Quality Bay Tree Laurus Nobilis plaited stem 5ft 6in inc pot height 55cm 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.
