This well tended local neighbourhood park garden is actually a quiet memorial to a deceased spouse.
Chatting with the lady who was working on the garden (planting tulips) I learned that she was carrying on the work of her husband, who had passed away the year before. He had worked in some area of the city agriculture/environmental works department and had shared his love and knowledge of plants and gardening over the years of marriage.
His volunteer work maintaining this patch in a local park had been his gift to the neighbourhood.
