The Chicago Botanic Garden, The Morton Arboretum, and the nursery consortium Ornamental Growers’ Association of Northern Illinois (OGA) are the corporate members of the Chicagoland Grows®, Inc., plant introduction program.
Founded in 1986, the introduction program is dedicated to the development, testing, and introduction of landscape plants to the industry, gardens of the Midwest, and comparable climates in the USA, Canada, and Europe.
In support of Chicagoland Grows, Chicago Botanic Garden initiated a perennial plant breeding program in 1995, which has developed to date the PrairiebluesTM false lupins, the MeadowbriteTM coneflowers, and other selections.
Plant propagation at Chicago Botanic Garden supports the breeding program in two general ways.
The breeding program produces seed from controlled crosses, which are then germinated in-house and grown on for further breeding.
Once individual plants are selected for testing as potential introductions, then vegetative propagation protocols are applied to ensure the genetic integrity of the propagated plants.
The remainder of this paper will present the seed and vegetative propagation protocols we have utilized for selected genera in the breeding program.
The Chicago Botanic Garden is in northern Illinois in U.S.D.A. Zone 5a, for comparison of propagation dates in other regions.
