Craig snowdrops have evolved over the last 40 or so years. Round the house and policies, a large variety has been planted with a varied flowering season stretching from the start of January until April and peaking mid-February. Large drifts of Leucojum vernum (winter snowflake) have started to naturalise here, and along the riverbank a variety of snowdrops swept down by the river have naturalised in the adjacent woodland, known as the Snowdrop Walk.
