Answer: Acidanthera take such a long season to bloom that you probably will need to start them off in a pot indoors but I would wait until April or so because they need lots of light and prefer heat; they need a warm soil and full sun and actually do fairly well grown in a pot all season. I would place a good number of them in the pot about two inches apart so that it looks full when they finally bloom.(They are very narrow upright plants.) It is rather difficult to get these to rebloom in areas where they are not hardy, so I would expect to treat them as an annual when grown so far north.
