The Sinningia aff. calcaria offered here is and rarely available species belonging to the family of Gesneriaceae, almost all of which are tropical. What few people suspect is that this species can be grown outdoors in the garden from late May to late September in a moderately sunny spot. That said, the plant can also be grown very well indoors, in a bright window location. As is the case with all Gesneria-like plants, they grow best in an airy and humic soil mixture consisting of equal parts leaf and needle forest soil, with occasional top-ups. After the growing season, the aboveground part of the plant dies off and then goes through a dormant period, during which the tuber can be kept on the dry side in a frost-free place. The specimen offered here is about 40 years old and has therefore formed a particularly large and massive tuber, which can therefore produce many flowers.
