A quick explanation about heirloom seeds; Heirloom seeds are from plants grown the old (Read BEST) way, No genetic modifications, hybridization, or splicing. Heirloom seeds tend to be expensive up front but less expensive because you can save the seeds and they will continue producing, UNLIKE many other commercially available seeds which will produce sterile seeds in the plants and vegetables that grow. Heirloom = one time up front cost. Standard GMO seeds = Continuos cost every year.
I bought mine from Survivalistseeds A google search will take you to Big Johns website. https://www.instructables.com/id/Growing-Heirloom-Vegetables/
The last photo is of my Black Krim tomatoes! They will turn a dark purple color sometimes with green stripes and they are DELICIOUS!!!
They're all I have up as of may 8 because I saved seeds last year.
