Gloxinia : Greenhouse Plants

W – warm, minimum of 13°C (55°F)

Family: Gesneriaceae

South America

The plants we usually call Gloxinias are modern hybrids mostly derived from Sinningia speciosa. These are either grown by seed which is very fine and should be surface sown on moist peat-based compost and kept light in a temperature of 21°C (70°F) in February or are acquired as tubers which should be potted with the top of the tuber barely covered with compost from January to March. After flowering during summer the plant will show signs of wanting to die down; gradually reduce watering and store the tuber in its pot in a dry warm place until the following February when it can be repotted and started again. Various methods of propagation are feasible including leaf or stem cuttings and division of the tuber. If you want to grow a real ‘over the top’ variety from seed try ‘Gregor Mendel’ which has huge double flowers with bright scarlet petals edged with white. Many more discreet varieties are available in various shades of pink, red and white. Keep water off the leaves as this will scorch them.
