The Lab

Micropropagation (Wholesale) Lab 

Founding: Knight Hollow Nursery Inc., was founded in 1981 by Deborah McCown.  KHN is considered a spin-off technology company from the work that Professor Brent McCown did in the 1970's at University of Wisconsin-Madison when he invented plant reproduction (cloning) method with Woody Plant Medium (WPM) in sterile test-tube culture, called micropropagation. After successful demonstration projects conducted by UW/industry cooperators, KHN was established to meet the demand for such services. 

The Product: Isolation into sterile culture, scale-up cloning, and marketing to whole sale growers of unique, high value plant specimens, specializing in contracts as exclusive propagator of patented woody ornamental plants and previously difficult-to-multiply specimens.

The Company Today: Knight Hollow Nursery, Inc, is an industry leader in woody plant tissue culture founded by Deborah McCown in 1981.  We are a family owed small business located in Middleton, Wisconsin.  The laboratory is lead by Deborah McCown, President, her daughter and Vice President, Elizabeth (Liz) Dunham, our Head Technician, Debra Davis, as well as some part time and temporary, seasonal workers. Brent McCown, now professor emeritus from University of Wisconsin- Madison, helps us on special research projects and consults on new technologies.  We are a contract based wholesale propagator but do have an extensive inventory of cultured plants.  Please contact us for an up to date plant list or for contract based orders.

Outside the Lab: We maintain a large plant rooting room with a capacity of 100,000 rooted microcuttings under LED lighting. This allows us to root and acclimate our own cultured cuttings making tissue cultured plants more accessible to a wide range of clients.  We also have two 100 ft greenhouses where we grow liner sized plants from our rooted tissue cultured cuttings. We ship year round, from all three of our sizes of plants, tissue cultured cuttings directly from culture, rooted acclimated cultured cuttings, and greenhouse liners. We have developed efficient and cost effective shipping methods to get our plants to our clients quickly and safely.
