In my experience here in California, two years from start to bloom is the almost absolute minimum, three years is common, and four is not surprising. The challenge to growing them indoors is that indoor conditions aren't great for them. They're cool growers, expecting a lot of day to night temperature variation. In the winter, the weather here is in the high 20s to the 40s F at night, and in the 60s during the day. They are also sensitive to light. Many of the plants keep their buds closed on cloudy days, presumably to protect the flowers from rain and to wait until days when pollinators will be active. Then on a sunny day between rainstorms, like today, everything pops open at once. I'm sure other on the list can give more info on what's needed to grow them indoors. Hope that helps, Mike San Jose CA (Zone 9, min temp 20F / -7C)
