Boophane
Here in central Indiana, I've had poor luck with Boophane as well as with most Brunsvigia. Bulbs coming in from the Southern Hemisphere have had a very hard time adapting, unlike Haemanthus and Scadoxus, for instance. They will need very bright light, if they are winter-growing. As Tim pointed out, it matters a great deal where your Boophane disticha come from -- some grow in winter-rainfall areas, others in summer-rainfall areas. These tend to be distinct ecotypes -- adapted to different ecological conditions -- even if they look identical.
Good luck, and be nice to your wife! I've kept mine for 46 years, but it's been dicey at times. Greenhouses can help preserve domestic tranquility.
