Peafowl

Hello everyone here is my challenge for you today as many know I have moved to a wonderful stately home as the head gardener at the home we have 4 Peafowl which get the run of the beautiful garden.

Well we have a back courtyard which has some dry stone wall running through it not high about 3 foot well the boss wants me to plant some plants into the nooks and cracks.

They must obviously be rockery type possible herb for the cook to use and most importantly nasty tasting for those beautiful but some what naughty birds any thoughts or previous experience greatly welcome as always Lester
