The first flowers to appear on Gillies Hill after the cold of winter are the snowdrops which surround the ruined Fir Park Cottage. In May the forest floor along Old Drove Road is carpeted with English bluebells. These bluebells, Hyacinthoides non-scripta, are commonly confused with the Scottish bluebell or harebell, Campanula rotundifolia, which blooms throughout the summer, is lighter blue in color and is usually found in the higher reaches of Gillies Hill.
