There are hundreds of candidates to provide colourful blooms, some even scented, for house and apartment.

'Bright light' means several hours direct sun a day, while filtered light means at the back of such exposed room or perhaps near a window in an east or north room. Always use room-temperature water--cold water is almost certain to cause flower and bud drop.
