Lilium is the most spectacular flowering bulb, with large scented flowers in a wide variety of colours. Many Lilium species grow well in pots as houseplants or in the garden.
Compost must be moist at all times during growing season. Copious water needed while in bloom, daily if necessary.
Feed with houseplant liquid fertilizer as flowers are dying to build up bulbs for next season.
Propagate by division of mature clumps in Autumn. They can be grown from bulbs planted in Winter and can also be raised from seeds in Autumn.
Most gardeners plant bulbs outdoors in the garden where it will flower every Summer. You might get another Lilium flowering, if you leave the houseplant in pot and move it outdoors, protect it from frost and bring it indoors in late Autumn. Force it to flower in high light and warmth.
Remove dead flowerheads to encourage stronger blooms.
Liliums need full light at all times, but shade flowers from hot sun.
If weather is very hot, spray around flowers in evening.
Loam-based #2 or soil-less.
Watering is necessary when transplanting, but be careful not to over water.
