Primulina fimbrisepala is a Chinese species that tolerates fairly cold temperatures in winter. Toshijiro Okuto, a Japanese professional grower, reports that it tolerates substantial cold, even snow, and that buds produced in the fall stay small and undeveloped until warmer temperatures in spring, when the plant can have a substantial crown of blooms.
The plant here was grown indoors under artificial light, and readily produced its beautiful flowers, but without the incredible crown of bloom that can be seen in some of Mr. Okuto’s photos below.
