I've never grown Rutgers but it's on the list.
I've had Black Krim for a few years now and it's a keeper in my MI zone 5/6 veg gardens. As well as red pear.
VERY rich flavor for a tiny tomato.
I've got Cherokee purple, & Mr Stripey and oxheart varieties to name a few which are new for this year. I really liked the green zebras very productive with really good flavor but DW wasn't a fan because they can be difficult to determine ripeness without palpating them. Which is fine for me but she's wants to know without checking them all the time.
Something else I openly admit is I have a list. On it are varieties of veggies I want to try. LOTS of them are tomato varieties, but there is plenty if other stuff. Each time I do a seed order or buy starts I get something off the list. This year I found Mr Stripey as starts so I figured this is the year I try them. This way I don't go completely bonkers and order everything but I can order an extra packet here and there as I find them or they become available. That's how I got my pink Berkley tie dye tomato seeds from Wild Boar farms. I have yet to start them but they have gotten rave reviews online. Same with my birdhouse gourd seeds from Baker creek. This way I don't forget a variety either that I want to try at some point.
For example I have Japanese Black Trifle, Anna Russian, and Costoluto Genovese on the list. When I place another seed order I'll add one of these to the list. Black beauty peppers were on the list and I have some this year.
I've gotten seeds from trades too that I have squirreled away just waiting for their moment in the sun.
I have a bunch if seeds I'm saving to start
at some point but when seems to be the elusive answer.
But I also plan my garden allowing for so many "I want go try these" plants too. Usually it's tomatoes but I have so many sq ft dedicated to them in the plan. Each year depending on what it is I'm going to try dictates where they go but the space is there. If it's a keeper then things are adjusted, if not oh well I tried it and now I know so let's try something else next season. I've had my share of duds believe me but knowing it's just a sample it's really not that big of a deal when it doesn't pan out. But that's also because I'm not counting on them as part of my harvest. Those are all extras I plant with the assumption they will fail and I won't get anything from them just in case.
This year most of that space and then some was used up by my glass gem corn. I don't ever go hog wild with a new variety if we're talking tomatoes I usually limit it to 4 per new variety to get a good sample to form an opinion. If it's something I grow from seed early to transplant outside Ill usually start a bunch of and give away the extras to other family or friends who garden. I mean who can say no to free tomato plants?
Sorry to be so long winded just giving you some insight into what works for me.
