O’Toole’s supports the Colorado economy with a commitment to always buy from local growers first.

Many of our annuals come from Apple Valley Greenhouse, in Penrose Colorado. Apple Valley has been a preferred grower for O’Toole’s since the 1980’s. Over our 3 decades working together, we’ve built a family friendship.
