Shamrock Nursery Inc. began in 1981 by Delray Kumm in O'Neill, Nebraska. As of September 2021, Katie Wrede has taken over ownership and will strive to offer the same great quality of customer service. We are a family-owned greenhouse operation committed to offering the North Central Nebraska's widest variety of plants including poinsettias, annuals, vegetables, perennials, roses, shrubs and brambles. Besides our home location in O'Neill we have Spring satellite locations in Neligh and Norfolk.
