I am having GREAT success keeping three potted Rosemary thriving in the house this winter. Two are in a south-facing window and one in an East-facing window, but under a grow light.
I learned that the secret is to keep them on a tray of water for extra humidity and to mist them every week. So far I have had none of the usual problems; leaf browning and dropping or mildew issues. They are supple, bright green and growing new leaves & branches.
I’m going to start boosting their fertilizer right now to see if I can get them to bloom for me this winter before they go out to the Greenhouse in late March, weather permitting.

Don’t want to get into shopping sites but here is an article on elderberry from NIH listing the health benefits, especially interested in respiratory benefits.

Would love a recommendation on which type for getting some plants in the spring. Thanks all.
hint: cut some branches, dive the rosemary, with garlic, add dijon mustard and olive oil, whisk till emulsified, marinate lamb chunks in that, then skewer on the branches and hit the bbq or broiler.. yow!
