Cain Greenhouse is proud to be a family-owned and operated greenhouse and plant nursery, located in Merrill, Wisconsin. We are proud to say we grow every single open-pollinated (over half are heirloom!) plant from seed, by hand, by the owner herself. All items are grown without pesticides, sprays, chemicals, fertilizers, etc.- just sunshine, water, and care. We strive to give each plant love and attention, as if we were going to plant it in our own gardens and give the food to our children. 

We offer fruit and vegetable starts, annual and perennial bedding plants, WI native flowers and grasses, climbing flower arrangements, herb starter plants, and flower and fruit hanging baskets. 

All of our plants are rated for zone 4 by our seed suppliers, unless noted, so you can feel comfortable growing them in the harsh Wisconsin winters. 

We often have posts and videos shared both on Facebook and Google of how we collect and save our seeds, planting and gardening practices we use, and other helpful suggestions to make your garden techniques more sustainable. 

New additions this year... We are expanding our garden art selection! We will have a much larger collection of crafts-- including wind chimes, spinners, feeders, bird houses, and much more. We will offer bags of soil and mulch from the local Hsu's Growing Supply! These will be available to purchase both during our business hours and as self-serve. We are also vastly expanding our WI native flower selection. Be sure to check out our flower page to see what we will have to offer!
