Really good selection of trees in particular. We found a beautiful crabapple tree we're really happy with. The folks who work there are very nice, trees come with a warranty, and the prices are good. Excellent place for gardening needs!

Staff is so friendly and helpful, and the plants are beautiful and healthy. Massive thanks to the STRONG young woman who helped us load our car with 3 giant & VERY heavy bags of peat moss yesterday, all with a smile on her face. Always love coming here!

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.
