This place is incredible! It's now one of my favorite places in Mukwonago. It's always set up for different seasons and holidays, but the greenhouse is temp controlled and always open. Where you walk in, they have a lot of home decor and gift-y items as well as bird feeders and fairy garden/zen garden/terrarium products. In the greenhouse, there's a surplus of houseplants, herbs, succulents, and as I write this, plenty of gorgeous poinsettias. For someone who desperately misses the natural greenery during the Wisconsin winters, Thomas Greenhouse is like a burst of instant serotonin. I left with two houseplants and plan on looking up their next workshops - they do stuff like gnome making, create your own fairy garden, and more depending on the season.

Very knowledgeable, happy and friendly staff! The owner and employees are always so wonderful, and a joy to talk to. Plants have been pest free, healthy, happy, and gorgeous! Jennifer has went out of her way to accommodate me, and make me feel welcome. They usually have a decent selection of houseplants, succulents and even carnivorous plants, and lots of options for perennial and annual garden plants. They also offer a very nice selection of garden decor, pots, and potting materials. If you live around the area, I recommend giving this place a try! This is definitely my local "go to" garden center/greenhouse.
