Regarding Clivia specifically: It is well documented that the condition you describe is usually caused by a lack of cool temperatures during its winter dormancy period. The inflorescence will try to emerge but will be stuck down within the foliage, will try to open its blossoms, but will not fully emerge that season. Very disappointing when you've patiently waited a year for it to bloom. For reliable blooming, growing conditions for Clivia need to be as close as possible to its native habitat (South Africa/RSA), which translates to cool, (i.e. *not* warm), and dry-ish conditions during its winter dormancy. Once the inflorescence is noticed deep within the foliage in very late Winter/Early Spring, watering needs to be commenced for the peduncle and inflorescence to develop to its potential. (Temperatures can get down to the upper 30s F in my hoophouse and 40s F in the cold bedroom during winter, but it is said that mid 50s F should suffice.) True, Clivia is definitely a shade plant, and very deep shade will result in larger, broader, darker green foliage, but reduced incidence of blooming. Too much sun will cause leaf scorch and burned, unsightly blossoms. AND.....too little light just prior and during bloom will lead to washed out colors. Ultraviolet light (dappled) especially, or at least very bright light indoors or out (not direct, unfiltered, hot sun) significantly adds to more intense flower coloration. Also, Clivia are notorious for skipping a bloom season for no apparent reason. Too much water at any time will lead to roots rotting; excellent soil drainage is of paramount importance with Clivia. Also, in my experience, Clivia are heavy feeders and respond well to fertilization. I don't want to be discouraging -- they are relatively easy to grow as long as their requirements are met. Even if they don't bloom, they can be handsome, shade tolerant, indoor foliage plants (aka - 'dust catchers'). Like most things, it's a matter of balance. Good luck, Mike Onalaska, WA. old zone 7 On Sun, Mar 2, 2025 at 11:20 AM piaba via pbs < pbs@lists.pacificbulbsociety.net> wrote: > thank you for your replies but this plant is in a home, growing on a north > window with no direct light. it has bloomed normally before. > > ======== tsuh yang > > On Sunday, March 2, 2025 at 12:53:56 PM EST, Eric via pbs < > pbs@lists.pacificbulbsociety.net> wrote: > > Thanks for asking the question.
