Aquilegia chrysantha 'Yellow Queen', early June. "Attractive grey-green, broadly divided leaves and long graceful stems supporting forward-facing pale lemon flowers. The species in its native southwestern United States is pollinated by long-tongued hawk moths, able to reach into the backswept spurs containing the nectar. 'Yellow Queen' flowers for longer than most columbines...Reliably perennial but tires with age." [Fergus Garrett, Great Dixter, Gardens Illustrated magazine, May 2013]
