Michael J. Kartuz joined ABS in the early 1950’s. He had just started a mail order nursery that would become Kartuz Greenhouses. As Kartuz Greenhouses, Mike combined his own skills as a hybridizer with those of other hybridizers for the next 70 years. For those 70 years Kartuz Greenhouse was a constant supporter of ABS, a source of amazing plants, and a center for hybrid begonias in profusion. Mike passed away in 2022 and the Sacramento Branch of ABS put together this tribute to the man.
