To the genus sinningia belong dozens of species of flowering plants of tropical origin, widespread in nature in Central and South America, Sinningia speciosa is the botanical species from which they have obtained the large-flowered hybrids grown throughout the world, is native to Brazil.
It is a medium sized tuberose, with deciduous leaves, also called Glossinia; each single tuber produces a small dense and roundish shrub, formed by big velvety leaves, wrinkled, slightly fleshy, of pale green colour, with showy veins in relief; the lower page of the foliage is of reddish or pink colour. During the spring months, and often also in autumn, thin stems rise between the leaves of the Glossinia, carrying small trumpet-shaped flowers, blue or purple in colour.
There are many hybrids, characterized by very large flowers, white in the outer part of the cup, but very showy in color in the inner part, in shades of red, purple and lilac, the petals are spent and velvety. During the cold or very dry months, the gloxinias go into vegetative rest, losing all the aerial part.
These plants in Europe are particularly suitable for indoor growing, as they fear frost; they are grown in a bright place, but not exposed to direct sunlight. The plants of Sinningia speciosa can be taken outside during the warm months, in a shady and well ventilated place. Glossinia fears excessive summer heat, which can cause an early period of vegetative rest.

In early spring, when from the tuber of the sinningia speciosa the first shoots appear, we begin to water regularly, keeping the soil fairly cool and moist, but avoiding watering too much, not to encourage the development of rottenness. Let’s intensify the watering during the summer months, and let’s thin out them with the arrival of autumn, until they stop when the plant turns yellow and goes into a vegetative rest.
There are many hybrids of glossinia, some do not have a vegetative period, so they need regular watering throughout the year, others instead behave as annual and, once the period of vegetative rest has begun, it is difficult for them to be able to grow. sinningia speciosa produce new shoots.
From March to October, dissolve a small dose of fertilizer for flowering plants in the water of the watering; it is advisable to always add the fertilizer to the water of the glossinia, every time it is watered, but in a very small dose. Or you can spread on the ground some granular slow release fertilizer, which will dissolve every time we water.
These tuberous plants prefer fresh, moist, very soft and rich soils; usually we use universal soil, mixed with a small quantity of sand and pieces of crushed bark: in this way we will obtain a substratum which hardly causes stagnant water, but at the same time keeps fresh.
It usually happens by division of the rhizomes or by leaf cutting; it is also possible to try to sow the sinninxes, but it is good to get the seeds from specialized dealers, as often the seeds of sinning are sterile, or it is likely that the plants will not be identical to the mother plant.
Glossinia, Sinningia – Sinningia speciosa: Parasites and diseases
The key word for the best treatment of gloxinias is watering: an excess of water easily causes rottenness of the tubers, a shortage of water brings the plant into vegetative rest very quickly. Sometimes they are attacked by mites or rust.
