Never heard of Territorial so I'm bookmarking their site for later browsing, they look like they have a nice selection of various items and I love thinking ahead, even 2-3 years down the line.I did things a little different this year for my fall seeds. I decided what I wanted to grow and then decided on preferred varieties. Then I did an online search for those varieties to see who had them. Three names kept popping up, Baker Creek, Burpee, and Territorial.
So I went to each site and looked through their varieties and for everything I wanted I wrote down what my variety would be if I ordered from them, cost, and how many seeds per packet. Baker Creek was sold out of a lot of stuff and I was surprised that their cost comparison wasn't very good on what they had. Burpee seed packets are a lot bigger than I normally need so their costs weren't great but they were also sold out of a lot. Territorial came out the clear winner for my criteria so they got my order.
I do tend to favor Baker Creek because I enjoy having easy access to reviews (which I add to myself) and they offer free shipping. Plus the fat catalog is a nice surprise in fall/winter, I flip through it and then pass it on to my mother in law.
I also just placed an order with "Totally Tomatoes" to get the last few things I was missing for 2021 (more tomatoes, radishes) - don't know anything about the company but they had the last couple of seeds I was looking for, so figure I'd give them a shot.
