Located North of Chicago, nestled on the Wisconsin-Illinois border, is a wholesale container nursery called Intrinsic Perennial Gardens. Started in 1992, they specialize mainly in one gallon perennials, including ferns, grasses, shrubs, vines and green roof plants.
A Family owned and operated company, Brent Horvath is the current owner of Intrinsic Perennial Gardens. But the family business stretches way back into the 1970s, when his father, Lajos, created Intrinsic Landscaping and his mother, Trudy, ran Flowers by Intrinsic. In 2002, Jörg Breuning introduced modern green roof technology to Brent and his brother, Kurt, of Intrinsic Landscaping. Working together, our companies created the green roof on the Peggy Notebaert Nature Museum in Chicago. Not only is Brent the president of Intrinsic Perennial Gardens, he has recently shared with us a list of his top picks of native plants which would specifically flourish on green roofs. Also in the line to appear on bookshelves in the fall is a book by Brent on Sedum, published by Timber Press.

Intrinsic Perennial Gardens strives to grow the best ornamental plants as naturally as possible. Their unique operation allows them to breed and introduce new plants into the trade. They offer over 900 varieties of species, 50 of which have been selected, bred and introduced into their nursery. They propagate around 80% of their own material. Approximately a third is done by seed, a third by cuttings and a third by division. Included on their 23 acre farm is a one acre field specifically for plug production.
