Sage Plants

Sage #1, grown at home. The oldest leaves are turning yellow, and the plant doesn't have as many leaves overall as the plant grown at my friend's house. The friend's house/my home difference isn't as pronounced with the sage as with the basil, however. I feel like I'm back in elementary school doing a science experiment with this dual location thing.

Sage #2, grown at friend's house
The leaves all seem kind of small to me. My gardening book does not recommend starting sage from seed. I think that's ridiculous. All sage has to start from a seed at some point. Why shouldn't I be the one to do it?

Sage #2, grown at friend's house

This is the sage plant that used to be at home and since taking it to FH it's really flourished. It's a little asymmetrical but it's growing.

The newest leaves on my curling leaf sage plant are very soft and furry and a softer shade of green. This is how I think of sage. The older leaves are bumpy and have always been that way even before they got sick. Does sage not produce furry leaves until later in life, or if the leaves start out that way when they are young and then get bumpy?
I read somewhere that starting your own sage from seed was a bad idea. So far, I don't think that's true--the plants are doing fine.
