I don't have a lot of thyme (or time) for cultivating herbs. I blocked off an herb garden that is begging to be weeded and revamped and I hope to do that this year!
I grow the easiest herbs: mint, oregano, common sage. I put them in once and don't have to babysit them.
Mint can be invasive, but my mint patch is on the west side of my house, where the house and backdoor shade 1/2 of it and it was growing weeds when I bought the house. Even so, adjacent to the house in the shadiest part, even the mint struggles without some watering. Still, I harvest it for mint sauce and fresh mint for lamb at Easter.
Oregano is just a tasty weed! It will and HAS taken over the bulk of my herb garden, and I intend to thin the oregano, if I do nothing else, and give some to my DD's. It is really easy to pull oregano out where you don't want it.
I put it several sage plants when I moved to this property. Only one survived, the common sage. I don't do anything to it, but I harvest the leaves for cooking chicken and turkey to season, even in the dead of winter where they are dried out, but still flavor very well.
I created a bed around my satellite dish next to a power pole and a sidewalk, where it was downright impossible to mow, and I plant 5-7 nasturtiums every year. They spread out and spill outside of the bed and is so much nicer than weeds. I have planted some bulbs there, too, the ones that I accidentally dug from another bed, stuck in my pocket and needed to replant. I am not sure that the peace rose in that bed survived last winter. Apparently roses are zone rated, something I discovered looking at a tag at WM for a pretty white rose that wasn't selling. It was rated zone 10. Could be THAT peace rose doesn't like living in IL.
I have Heard that Bee Balm is invasive. MINE wasn't. I planted it in a sunny part of my herb garden...and it died.
I think I need to plan it out better and I was considering blocking off each herb in it's own section with bricks. The garden is surrounded already with bricks and cement 1/2 moon bed dividers.
I am keeping a rosemary as a house plant. If it survives by on again off again care it will go outside this year as an annual.
Menard's'(hardware chain) clearanced some very nice basil last spring--75 cents/plant. I bought 5, kept three that grew to giant bushes, and gave my DD's 2, which I tucked in with their 2 tomato plants in a giant tree pot, and they grew huge, too. I harvested all of them before the freeze and dehydrated them, and they are stored in canning jars.
