Good perennial for indoors fall-spring and later outdoors?
We live in the Denver area and have a 4' dual T8 tube light over a shelf in the living room, which I use for sprouting seeds in peat pots in the spring.
But the light is kind of minimal for growing anything on a long term basis. I don't know if it's the spectrum of the tubes in there, or whether T8 tubes just don't put out that much light. ( I've since found some better lights that I may get, which are 10,000K tubes. )
But I was wondering if there was some kind of perennial that I could sprout from seed, or get from a nursery, that would green up the room from fall to spring ( flowering not necessary indoors ), and then I could plant outside permanently? Maybe I could do a row of them under that light. But the would have to be something that could survive from September to around late May, without a whole lot of light.
Anything green and perhaps pretty, for this?
