I've had two of these inside with very little light and they are doing excellent. I deadhead them regularly, and prune to encourage lateral growth. I keep the soil evenly moist. I'd like to put them outside for the summer, and I just did a test of putting one in full sun for a few hours and it began to wilt. I'll put them out in a shady spot soon and hopefully they'll continue doing well.

Actually, it is normal not to be able to keep this plant for a long time as it is a biennial. This means that when it has set some seeds, it will die like true annuals. You could keep it for a longer time by deadheading but I do not know for how long.
I'm in West Central Minnesota (Zone 3/4) and just recently bought this little guy at Home Depot. I'm glad to see the notes...because I already have the same fear as "Done Everything to Keep it Alive, but Fail In Spite of My Best Efforts" (or a title to that effect!!) As the flowering that was on it when I purchased it begins to fade, I'm wondering how it will go. I want it as house plant only, so I am really hoping it will survive my best efforts! It really is a pretty little plant. I like the bushiness of it and also find the continual flowering aspect a real +. I indicated "neutral" because I just don't know how it's going to go from here on out. I've had it about 2 weeks.

Lovely little plant, but one that I have found is near impossible to keep alive and flourishing for long. This pretty little thing has made my short list of Plants That Die in Spite of My Best Efforts & Study. Ah well.....you can't always win. I will continue to linger over the exacum when I see it, and plot in my head as to how I'll keep "THIS one" alive?!
This is a cute little plant. Small pretty blue blooms are on it constantly. I had this plant in a pot out on the patio and when the summer started heating up, it begin to look a little sad. I brought it in and it is doing well. I make sure I keep it watered regularly. This plant has remained rather small but blooms constantly. Its very pretty.

I've had good luck keeping this one alive. I almost lost it when I kept it next to the heater in the greenhouse. Apparently it doesn't like heat, especially dry heat. I trimmed off the dead lookingparts, kept it well watered and in the shade and it's started blooming again. I hope it keeps it up!
One vendor has this plant for sale.
