Ok, ok! Lol
MY vinca is surrounded on all 4 sides with 4 foot or more of concrete, so I am not as worried. And while I agree that the mint is better at deterring insects, especially ants, my mileage seems to vary when you compare invasiveness. Mint took me YEARS to eradicate and tried to choke out EVERYTHING I put in a bed it decided to "visit". My vinca I used as ground cover IN my garden beds for under bushes and such and I simply gave it a haircut now and then with scissors.
There is not a single seed that I have yet been unable to find on either rareseeds.com (Baker Creek Heirloom Seeds) or my new favorite seedman.com (use code FirstOrder to save!). I have actual tea plants sprouting, Roselle (red zinger tea hibiscus), tons of medicinal plants (including ephedra, my beloved old friend!), and even belladonna! I am totally ready for the Zombie Apocalypse! And I have a crapload of fruit bushes coming from directgardening.com. I have sand cherries, honeyberries, loganberries, red and white currents, old fashioned roses that have lots of rose hips, runner beans, arctic kiwi, rhubarb...
I'm sure there are tons I did not mention, as I have 100+ seed packets.
I am an herbal witch and really do love my gardening. Lol
