I love nicotiana for the wonderful fragrance they waft into warm summer nights, after sunset. This year I bought rustica seeds (instead of sylvestris). As rainbowgardener indicates, they are super tiny seeds and prone to building up static electricity in their seed packet, so it is indeed difficult to plant only a few. They germinate readily, are easy to grow and like lots of water. The leaves are large and sticky, like petunias. My seeds came packed in a little plastic zip lock bag inside the paper packet. I didn't know the bag took up most of the paper packet and when I cut it open, I inadvertently sliced off the bottom of the bag. Nicotiana seed fell all over the floor of the greenhouse. Swept it up and dropped it into shallow trays of moist soil. Now I have a ridiculous excess crop of nicotiana that I'll no doubt, be planting all over the yard and giving away in a month or so. Since it is raining today, I'll snap some pictures later and load them up here. The only tedious part is getting the seedlings separated. They don't mind being crowded, as long as they get enough moisture, so wait for the leaves to be pea-sized or larger. Wet the soil prior to trying to separate the seedlings. You can use tweezers (gently) to pull the plants apart by the leaves. Even a little of each plant's root is enough to plant. You might keep a little cup of water handy to dip the root clumps in to help pull apart the plants. My plants never seem to suffer any transplant shock, and perk up within a day or so. Nicotiana grows well in sun or shade, and I've noticed that they wilt or droop when its really hot (July and August), but perk back up when given water. I've never fertilized mine, but I might try some bloom booster this year. Cut away spent blooms, and they will bloom again. Next year, look for seedlings to pop up in the area you grew them this year, but they tend to come late (in zone 5) when the soil has warmed up (June).
