Q. Why doesn't my Clivia bloom?
Clivias bloom only once a year. Also they bloom after they have developed some maturity. I don’t know the age of your plant, only that you have had it 18 months. Clivias bloom best when they are pot-bound. Mine usually bloom late winter, having been wintered- over in a cool, sunny room. I have them up against a window where they get good light all winter. They then summer outside. Other Clivias of mine that are in warmer rooms with less sun, bloom when I put them outside mid to end of May. Have patience, they will bloom and give you pleasure. To learn more, check out Harold Koopowitz’s book Clivias (Timber Press, 2002) from PHS’s McLean Library. Here’s a preview.
