I don't know what area your mom is in to make recommendations. I have personally been to Ritchers and it's dangerous in there for plant lovers.

Do check with US Customs about bringing live plants in dirt across the border - I'm not sure if you can do that unless you have a clearance certificate. It would be awful if you purchased plants only to have them seized at the border. Dry root plants I believe are safe because they don't transport dirt.

Please do your homework before you buy. I'd listen to your customs people before any advice from a vendor.

I hope you enjoy your visit.

I should clean my eyes - Toronto area.

Here's the link from your government website. You may want to call them in advance to discuss what is needed if you do purchase.

Enjoy your visit with your Mom!

Richters is north of Toronto and not far from my area.

I would suggest you pay a visit to Sheridan's located in Unionville. Directly across it is another plant seller.

And there's Angelo's garden in Vaughan, Tree Valley in Richmond Hill and in Stouville.
