Answer: Thirty years old?? Wow! That is an accomplishment in itself. This plant is botanically known as Rhoeo discolor 'vittata', I know it as "Moses in the Cradle". It is also known as a Boat Lily. Compare these ideal growing conditions against your conditions and make modifications as needed: needs average warmth in the winter, 50-55F minimum. It should be kept in bright light or semi shade, absolutely no direct sun in the summer. Soil should be kept moist in the months of April through August, reduce watering September through March. Leaves need to be misted frequently with a fine spray. Repot every year in the spring; bushy plants can be divided. Side shoots should be removed as well. "Moses" is extremely intolerant of drafts, hot or cold, so watch out for those. Fertilize only April through August with a general houseplant fertilizer according to package instructions. Following these cultural guidelines should help your plant to flourish and eventually bloom. Even under perfect conditions it does take "Moses" a good while to bloom and have the color variations.
