Absolutely disappointed with how we were treated when we entered this green house. A man was painting on the other side of the door that's says entrance and come on in we're open.
He got rude and told me "I closed that door for a reason." And that " you're lucky that something didn't fall on your head".
Which is absolutely appalling because first of all it's the main entrance. Second of all there was no warning or caution sign.
So if something did hurt me I'm able to sue you. So your lucky I didn't get harmed. I'm just appalled that this was my first experience. I was really excited to check

Friendly staff who are readily available to assist you with suggestions & recommendations for your gardening needs. Good selection of pots, annuals & perennials with detailed labels providing information on sun/shade requirements, pictures of the item in bloom, etc. Prices are reasonable given the very good quality of their products.

Have been coming here for many years when we lived in the Orangeville area..now that we have moved to Owen Sound, we make a special trip to pick up hundreds of $$$ worth of plants every spring for our gardens there. By far the best greenhouse products we have found anywhere!!!! Worth the drive!!!!!

Thanks so much for your help on Sat. May 8th. My girlfriend had been looking for certain impatiens, one of the young ladies found 2 flats of the perfect pink! We dropped them off yesterday, my girlfriend gave me a virtual hug & I'm passing onto all who work at the nursery. You, on Saturday were her Lifesaver.

The flowers are lush and plentiful here! So many healthy plants to choose from to add to your garden. Can be pricey compared with other gardens centers but you will not be disappointed in the quality and the blooms will outlast your neighbours !

I love this place! I am a repeat customer and enjoy my experience every time I come here. It has a unique environment and nice landscapes in the spring summer seasons. Staff is very helpful and have answered all my questions and given great gardening advice. I have bought many things here and my two prized Japanese maples were bought here. They both were rare species and this place had them and they were in great condition and still strive very well today. Most perennials i have bought here are strong and surviving today. Great selection and healthy plants overall. Highly recommend
