Coleus makes me feel better about sowing seeds indoors. I tried them last year for the first time and they were the only things other than tomatoes that worked for me indoors.

Someone on the "Growing from Seed" forum gave me some really good tips on Coleus:
1. they stall out at a certain point and seem to not grow...just keep watering them and they will suddenly start growing like crazy
2. They are hungry little buggers...they LOVE water. I give them a good soaking once a week (sometimes twice) and alternate giving them a watering with weak fertilizer solution every other watering.
3. They like shade, but they really like heat.
a. I have had mine in a room with a southern exposure but away from the direct sunlight. They seem to like that a lot.
b. Last year, it didn't seem like my seedlings were doing much-- I probably started them in March. I put them outside when it got warm and they EXPLODED! If I hadn't been so anxious to protect them from white flies inside, I still would have them (I killed them with indoor plant pesticide when I brought them in in the fall.)
