Glen McCombs, owner of Plant Fair Nursery in Star Valley, has more than a green thumb â he may very well have gardening genes. âIâm a fourth-generation nurseryman,â he says, âMy great grandfather, Jeremiah McCombs, started a nursery in Ontario, Canada in 1890.â Glen has worked in the nursery business all his life, except for four years in the armed services. Thanks to years of experience at Tip Top Nursery in Phoenix and people he came to know in the industry, Glen says he was able to increase significantly the plant palate offered in Payson when he opened his store in 1983.
