Some species have white and blue. Beginning normally in the winter and spring the flowers will come out in succession over a period of time. In colder climates greenhouse grown plants can bloom intermittently all year round. According to Graf by keeping the plant cool and dry in the spring flowering can be delayed until summer. If started from seed it takes five to seven years for blossoming to begin.
Some text suggest three years from seed.
Even as cut flowers the succession of bloom will continue to occur and last for weeks if the water is changed regularly. The flowers have no scent. However flowering will be diminished at 2000 ft-candles. This may require some daily misting during the dry winter months. In areas of the world where there is no danger of frost it can be planted outdoors.
