This is the British Baneberry or Herb Christopher, having shortish black rootstocks, much-divided leaves, and erect racemes of white flowers in May, afterwards followed by black, red, or white poisonous berries. This plant sells well with nurserymen, but is not a market flower. It is easily grown in moist sandy peat and loam in shady spots, and may be increased by division.
