Thanks for the tips on the Rosemary tips! My Mom's huge shrub has plenty of material to try again. I will when it's a little warmer out there.
Free food DOES rock! Ever plant carrot tops and/or celery stumps? Potato eyes? My son loves these experiments. I think if we did it at the right time, whenever that is, we'd get some food from it. Lots of cool foliage so far though, which has given itself back to the soil. I'm still kinda clueless growing veggies down here (I'm from OH until a few years ago.)
Yes, you should be able to get a plant from a borrowed section of the office plant. When you remove it, twist it until it lets go. Laying on the surface like this, it's cool to watch the roots come out and go down into the soil.
