A collection of orchids are on display in the hot house at Kew Gardens. They are delicate, small dashes of intense saturated colour. They live in a warm environment and steam is released into the air. You have to take off your winter hat, scarf and gloves, necessary for the freezing cold day. With a lily-pad ponds and green tropical plants, its like visual of a paradise. Outside, the rest of the park is muted, wintery, grey green, mud brown and cold.
