I have parsley seedlings after waiting, and waiting. I know parsley is slow to germinate, but good heavens, define "slow"!
The basil just didn't come up, and basil is one of the easiest herbs to grow. The few that came up were, gasp!, sage! Bad seed from a previously unused supplier. Darn!
I have six rose cuttings rooted and in quart pots, and I'm hovering over them like a mother hen. With our colder than usual winter the roots developed more slowly than usual, but they did root and are seemingly happy in their pots.
Propagation ain't for the faint of heart.
